The lab-grown diamond version of our Celtic trinity knot bridal set — a 6×8mm pear-cut IGI-certified lab-grown diamond at the center (D color, VVS clarity, top-tier specifications, ~1.2 carats), framed by Celtic trinity knot (triquetra) accents at each shoulder with real lab-grown diamond side stones along the edges. Paired with a matching chevron contour wedding band featuring a trinity knot at the V-apex point. Built entirely in solid 14K white gold (no plating, no rhodium-over-sterling). All white stones throughout the set are real lab-grown diamond — center, shoulder accents, and chevron band accents — with the center stone IGI-certified and shipping with its formal independent grading report.

Celtic Trinity Knot Accents
IGI Certification Included
Every ring at this listing ships with the original IGI (International Gemological Institute) certification report for the center stone, documenting the diamond's specific 4Cs grading (color, clarity, cut, carat weight) and confirming lab-grown origin. The certification is your independent third-party verification that the stone matches the specifications described — and is the standard documentation required by jewelry insurance providers to schedule the ring on a policy. The certification number is laser-inscribed on the diamond's girdle (microscopic, visible under magnification) to tie the physical stone to the document.
The Engagement Ring
Pear-cut IGI-certified lab-grown diamond center (6×8mm, D color, VVS clarity, ~1.2ct) in a 4-prong claw setting with milgrain bezel detail. Celtic trinity knot metalwork at each shoulder, accented by small round lab-grown diamond at the outer edges of each knot.
The Chevron Contour Band
V-shape chevron silhouette with a Celtic trinity knot at the apex point (pointing down) and graduated lab-grown diamond accents fanning up each side. Designed to nest below the engagement ring.
Top-Tier Diamond Specifications
D Color — the most desirable color grade for white diamond. Completely colorless, with no perceptible yellow or brown tint. Top of the GIA/IGI color scale.
VVS Clarity — Very, Very Slightly Included. Inclusions extremely difficult to detect even under 10x magnification by a trained gemologist. Eye-clean by an enormous margin and considered very high clarity in the diamond grading hierarchy (only Internally Flawless and Flawless are higher).
D color + VVS clarity is at the top tier of diamond specification — significantly above the "good enough" tier most lab-grown diamond engagement rings use.
Solid 14K white gold — the heirloom tier
"Solid gold" means the entire ring is gold alloy throughout — no plating, no gold-filled construction, no sterling silver core, no rhodium finish layer. 14K white gold is gold alloyed with palladium and other white metals to produce the cool bright white tone, hard enough for daily wear, and built to last indefinitely.
A solid 14K white gold ring is built to last a lifetime. It doesn't need replating, doesn't wear through, and holds resale and inheritance value in a way that lighter constructions don't. The cool white-metal palette pairs naturally with the colorless lab-grown diamond center: bright white gold lets the diamond's brilliance dominate the visual without warm-metal contamination. For a heirloom-tier engagement ring intended to last generations, solid 14K white gold + IGI-certified D VVS lab-grown diamond + lab-grown diamond accents throughout is the complete fine-jewelry configuration.
About the IGI-certified lab-grown diamond center
The center stone is a real diamond — same chemistry (pure carbon arranged in the diamond crystal structure), same hardness (10 on the Mohs scale, the hardest gemstone), same optical properties as a natural mined diamond. The only difference is controlled laboratory origin rather than mining. Lab-grown diamond is produced in advanced laboratories using either chemical vapor deposition (CVD) or high pressure high temperature (HPHT) growth techniques — the resulting crystal is chemically and structurally identical to a natural mined diamond.
This diamond is specified at the top tier of the 4Cs:
-
Color: D — the most desirable color grade for white diamond. Colorless, with no perceptible yellow or brown tint. D is the top of the GIA/IGI color scale.
-
Clarity: VVS — Very, Very Slightly Included. Inclusions are extremely difficult to detect even under 10x magnification by a trained gemologist. Eye-clean by an enormous margin and considered very high clarity in the diamond grading hierarchy (only Internally Flawless and Flawless are higher).
-
Cut: Pear brilliant — 6×8mm, classical pear (teardrop) facet pattern. Approximately 1.2 carats.
-
Hardness: 10 on the Mohs scale — the hardest gemstone available, ideal for daily wear engagement rings.
-
Certification: IGI — International Gemological Institute, one of the major independent gemological labs. The certification report ships with the ring.
D color + VVS clarity is the top tier of diamond specification. The choice matters: at this grade combination, the stone reads as crystalline pure white with no perceptible color cast, inclusions are invisible to the unaided eye, and the diamond holds its highest possible value among lab-grown stones.
Why IGI certification matters
IGI (International Gemological Institute) is one of the major independent gemological laboratories, alongside GIA (Gemological Institute of America) and AGS (American Gem Society). IGI specifically has become the dominant certifier of lab-grown diamonds because their lab-grown grading program has been the most extensively developed in the lab-grown space.
The certification provides three concrete benefits:
-
Third-party verification: the stone's specifications (D color, VVS clarity, carat weight, cut) are independently confirmed by gemologists who have no commercial interest in the ring. You're not just trusting our claim; you have a separate institution backing it up.
-
Insurance scheduling: most jewelry insurance providers require a written gemological certification to schedule a ring on a jewelry policy. The IGI report meets that requirement.
-
Resale documentation: if the ring is ever resold, the IGI certification provides the documentation needed to validate the stone's grading independently — significantly more valuable in the secondary market than an uncertified stone.
The certification report ships with the ring in a sealed protective sleeve. The certification number is laser-inscribed on the diamond's girdle (microscopic, visible under magnification) to tie the physical stone to the certification document, preventing certificate-and-stone swaps.
Lab-grown diamond vs natural mined diamond
Both are real diamond — same chemistry, same hardness, same optical properties. The differences are origin and price:
-
Lab-grown diamond is created in months under controlled laboratory conditions. Production scales mean lab-grown diamonds at any given 4Cs grade are significantly more accessible than natural mined diamonds at the same grade — often 30–60% of the equivalent natural stone's price at this carat size.
-
Natural mined diamond forms over billions of years underground, then is mined and brought to market. The price premium reflects mining scarcity, cultural significance, and the resale market for natural mined stones (which is more established than the lab-grown resale market).
For buyers who want a real diamond engagement ring at the top tier of 4Cs specifications without the natural-mined price tag, lab-grown is the practical choice. The visual experience, durability, and daily-wear behavior are identical to a natural mined diamond at the same grade. If you specifically want natural mined diamond at this design, we can quote it as a custom order — significant price premium, but the option is available.
Honest disclosure on resale value: the lab-grown diamond resale market is younger and less developed than the natural mined diamond resale market, so lab-grown stones typically don't hold resale value as strongly as natural mined diamonds of equivalent grade. The resale market for lab-grown is growing rapidly as the broader market matures, and IGI-certified lab-grown stones command higher resale values than uncertified ones. The certification documentation accompanying this ring meaningfully supports any future resale or insurance purposes.
About the lab-grown diamond accent stones (matched throughout)
The small accent stones at the outer edges of the Celtic knot accents on the engagement ring + the graduated accents along the chevron contour band are also real lab-grown diamond — the same material as the center stone, just at smaller carat sizes for the accent role. The accent diamonds are matched to the center stone's color grade (D color) and graded at SI clarity or better — typical for accent diamond setting at this size where individual stone certifications would be impractical but quality consistency across the matched set is maintained.
This creates a unified all-diamond composition throughout the set, with three concrete advantages over mixed-stone configurations:
-
Consistent optical character: all white stones in the set show the same brilliance and sparkle pattern of real diamond. Mixed configurations (diamond center + moissanite accents, or diamond center + CZ accents) show different sparkle patterns between center and accents, which can read as visually inconsistent.
-
Consistent durability: all stones at Mohs 10, the hardest gemstone material. Mixed configurations have hardness mismatches that create care-protocol differences.
-
Defensible value proposition: "all diamond throughout" is the strongest possible value statement for a diamond engagement ring at this tier.
About the Celtic trinity knot (triquetra) accents
The interlaced metalwork elements at each shoulder of the engagement ring — and at the apex point of the chevron contour band — are Celtic trinity knots, also called triquetras. The triquetra is one of the oldest Celtic symbols, dating back over 1,000 years and appearing in pre-Christian Celtic religious art, the Book of Kells (~800 AD), and later Christian Celtic tradition where it became associated with the Holy Trinity (Father, Son, Holy Spirit).
The symbolic meaning has multiple traditional interpretations:
-
Christian Celtic tradition: the Holy Trinity (Father, Son, Holy Spirit) — three persons of one divine unity
-
Earlier Celtic tradition: threefold aspects of nature or the divine, with various interpretations across the broader Celtic cultural region
-
Modern interpretation in bridal jewelry: three forces becoming one (the union of two individuals into a partnership that's larger than the sum of its parts), past/present/future, or mind/body/soul
The interlaced line in a triquetra has no beginning and no end — like all Celtic knotwork, it represents endless continuity, eternity, and unbroken connection. For Irish, Scottish, Welsh, Manx, or Breton heritage buyers, the triquetra carries personal cultural significance beyond the general design appeal.
In solid 14K white gold with all-diamond stone composition, the open Celtic knotwork reads with the substantial weight and presence of full fine-jewelry construction — the metal's density gives the interlaced lines a fuller, heirloom feel on the finger, and the diamond throughout creates consistent fire and brilliance across the entire ring face.
About the chevron contour band
The matching wedding band uses a V-shape chevron silhouette with a trinity knot at the apex point and graduated lab-grown diamond accents fanning up each side. The chevron silhouette is one of the classical contour band shapes for pairing with pointed center stones (pear, marquise, kite) — the V-apex points downward, nesting below the engagement ring's center stone rather than rising above it.
Worn together, the two rings read as a vertically symmetrical composition: the pear lab-grown diamond at the upper center, the chevron's trinity knot at the lower apex, and the engagement ring's two shoulder triquetras completing the Celtic-symbolic framework. The three trinity knots across the two rings create a layered symbolic composition with all-diamond sparkle throughout the set.

Sizing & care
Standard sizes 3–10 (US) available in the dropdown. Larger and smaller sizes are available on request — message us before ordering. Half and quarter sizes available. Sizing can vary slightly between jewelers and mandrels — up to half a size — so if you've been sized recently elsewhere, check our sizing guide before ordering or message us for a complimentary ring sizer.
Lab-grown diamond is one of the most durable engagement-ring stones available — Mohs 10, the hardest gemstone, suitable for daily wear including ultrasonic cleaning. The pear cut's pointed tip is the most vulnerable part of the center stone, though diamond is hard enough that this is a minor concern. All accent stones throughout are also lab-grown diamond at Mohs 10 — no soft-stone weak link in the ring's care profile.
Solid 14K white gold doesn't need replating and holds its tone indefinitely with normal wear. A soft jewelry cloth keeps the white gold bright. Clean the ring with warm water and a soft brush; ultrasonic cleaning is fine for the diamond stones (the metal prefers gentler care). Avoid harsh chemicals (chlorine, bleach, ammonia) as general best practice. Store both rings separately when not worn so prongs and accent stones don't catch on each other. Keep the IGI certification document with your insurance paperwork; if it's lost, replacement certification can be obtained but requires sending the ring back to IGI.
Frequently asked questions
Is this a real diamond?
Yes — real lab-grown diamond. Lab-grown diamond is genuine diamond (pure carbon arranged in the diamond crystal structure), with the same chemistry, same hardness (Mohs 10, the hardest gemstone), and same optical properties as a natural mined diamond. The only difference is controlled laboratory origin rather than mining. It is not moissanite (a different material), not cubic zirconia (a different material), and not a simulated diamond. It's real diamond, just lab-grown.
What does IGI certified mean?
IGI (International Gemological Institute) is one of the major independent gemological laboratories. IGI certification means the diamond's specifications (color, clarity, cut, carat weight) have been independently graded by IGI gemologists who have no commercial interest in the ring. The certification ships with the ring as a sealed document, and the certification number is laser-inscribed on the diamond's girdle (microscopic, visible under magnification) to tie the physical stone to the document. IGI is the dominant certifier of lab-grown diamonds, alongside GIA and AGS.
What does D color VVS mean?
Top-tier diamond specifications. D color is the most desirable color grade for white diamond — completely colorless with no yellow or brown tint. D is the top of the GIA/IGI color scale. VVS clarity means Very, Very Slightly Included — inclusions are extremely difficult to detect even under 10x magnification by a trained gemologist. Eye-clean by an enormous margin. Only Internally Flawless (IF) and Flawless (FL) are higher clarity grades.
How does lab-grown diamond compare to natural mined diamond visually?
Visually indistinguishable to the unaided eye. Same chemistry, same hardness, same optical properties (brilliance, fire, scintillation). Even trained gemologists need specialized equipment (typically advanced spectroscopy) to reliably distinguish lab-grown from natural mined at high grades. The visual experience, durability, and daily-wear behavior are identical to a natural mined diamond at the same grade.
What's the price difference vs natural mined diamond?
Significant. Lab-grown diamonds at any given 4Cs grade typically cost 30–60% of the equivalent natural mined stone's price at this carat size. The savings reflect production scale (lab growth has improved dramatically in the last decade), no mining costs, and the lab-grown market's faster supply expansion. For buyers who want top-tier specifications (D color, VVS clarity, certified) at an accessible price, lab-grown is the practical choice.
Will lab-grown diamond hold its value?
Honest answer: lab-grown diamond resale market is younger and less developed than the natural mined diamond resale market, so lab-grown stones typically don't hold resale value as strongly as natural mined diamonds of equivalent grade. That said, the resale market for lab-grown is growing rapidly as the broader market matures, and IGI-certified lab-grown stones command higher resale values than uncertified ones. The certification documentation accompanying this ring meaningfully supports any future resale or insurance purposes.
What's the difference between this and the moissanite version?
Different stone material entirely. Moissanite is silicon carbide — its own distinct gemstone, not diamond. Lab-grown diamond is real diamond — same material as natural mined diamond, just lab-grown. Both are durable for daily wear (moissanite Mohs 9.25, diamond Mohs 10), but they have different optical signatures (moissanite has more "fire" / rainbow flash; diamond has more brilliance / white light return). Lab-grown diamond is significantly more expensive than moissanite at comparable specifications. Cultural significance, established resale market, and traditional bridal preference favor lab-grown diamond; greater accessibility and more visual fire favor moissanite. Both are legitimate choices for buyers with different priorities.
Can I upgrade to natural mined diamond instead?
Yes, at significant additional cost. Lab-grown is the default at this tier because it pairs top-grade diamond specifications (D VVS) with accessible heirloom-tier pricing. Natural mined diamond at the same specifications would significantly increase the ring's total price (typically 2-3x for equivalent 4Cs grade at this carat size). If you specifically want natural mined diamond — for cultural significance, traditional resale value, or the preference for natural origin — we can quote it as a custom upgrade with GIA certification.
Are the side stones also real lab-grown diamond?
Yes — the round accent stones in the Celtic knot accents and the chevron contour band are also real lab-grown diamond, the same material as the center stone. Color-matched to the center (D color) and SI clarity or better. This means the white stones throughout the ring (center + accents) are all real diamond — meaningful upgrade over the moissanite version (real moissanite accents) or the sterling silver version (CZ accents), creating a unified all-diamond fine-jewelry composition.
What does the Celtic trinity knot symbolize?
The triquetra (Celtic trinity knot) is one of the oldest Celtic symbols, dating back over 1,000 years. Multiple traditional interpretations: in Christian Celtic tradition, the Holy Trinity; in pre-Christian Celtic tradition, threefold aspects of nature or the divine; in modern bridal interpretation, three forces becoming one (the union of two individuals into a partnership larger than its parts), past/present/future, or mind/body/soul. The common thread: "three forces unified into one" with the unbroken interlaced line representing endless continuity. For Celtic heritage couples, carries personal cultural significance.
Is this ring appropriate for Celtic heritage couples?
Yes — for Irish, Scottish, Welsh, Manx, Breton heritage couples, the triquetra carries personal cultural significance beyond the general design appeal. The symbol has been part of Celtic cultural tradition for over a millennium. The heirloom-tier all-diamond solid gold construction makes this appropriate for the most significant heritage bridal contexts — traditional Catholic weddings with Celtic heritage, handfasting ceremonies, or any wedding tradition where the cultural symbolism resonates at fine-jewelry tier.
How big is the center stone?
6.0 × 8.0 mm pear cut, approximately 1.2 carats. The pear cut's elongated vertical orientation visually elongates the finger and gives the stone substantial presence — it reads larger than a 1.2ct round would. Larger center sizes (1.5ct, 2ct+) available on request for a custom quote.
How durable is the ring for daily wear?
Exceptional. All stones throughout (center + accents) are lab-grown diamond at Mohs 10 — the hardest gemstone material available. Handles daily wear excellently, isn't prone to chipping. Suitable for active lifestyles and indefinite daily wear. Ultrasonic cleaning is safe for the diamond portions of the ring.
How does engraving work?
Complimentary engraving up to 16 characters is included. You can specify the text at checkout or message us with the engraving details before ordering. Engraving is interior (inside the band), the standard placement for engagement ring engravings.
Can I get this in 14K yellow or rose gold instead?
Yes — both are available on request at the same construction. White gold (this listing default) preserves the cool classical-bridal palette and lets the diamond brilliance dominate without metal-tone interference. Yellow gold against the colorless diamond reads as warm vintage-classical (valid alternative aesthetic); rose gold softens the design into romantic register. 18K upgrades (white, yellow, or rose) are also available at additional cost.
Will this ring stack with additional plain bands?
Yes. The two-ring set works as a complete bridal stack on its own, but both rings layer cleanly with plain bands, eternity bands, or other shaped rings if you want to build the stack out further over time.
How long until my ring ships?
Made to order, 2–6 week production timeline. Modifications (different metal, custom engraving, larger diamond, natural mined diamond center upgrade, custom sizing) may extend the timeline. The IGI certification process for the center stone is included in the production timeline. We'll confirm production timing when your order is placed.
Do I need a separate appraisal?
The included IGI certification documents the diamond's 4Cs specifications and confirms lab-grown origin, which is typically sufficient for jewelry insurance underwriting. If you specifically want a separate independent monetary valuation appraisal (which estimates the ring's retail replacement value, distinct from the IGI gemological grading), that's available as an additional service at checkout. Most buyers don't need both; the IGI certification alone satisfies most insurance requirements.
Are the stones ethically sourced?
Yes. Lab-grown diamond has no mining footprint and is fully traceable from controlled-lab origin. Natural mined diamond upgrade options sourced from ethical conflict-free origins with verified fair-labor practices.
What's included in the box?
Both rings, the original IGI certification report (in a sealed protective sleeve) for the center stone, a free luxury velvet jewelry box, and a care card. Free USA shipping.
