Every remarkable stone deserves a paper trail. This sapphire and diamond engagement ring in yellow gold carries one: an IGI-certified, lab-grown pear-cut diamond — D color, VVS clarity — documented down to its own serial number, set between genuine lab-grown blue sapphires on a band traced with the fine, woodland detail the Feyra design is loved for.
Certified, down to the serial number
The center diamond arrives graded by IGI, one of the world’s leading gem laboratories, and every ring includes a certificate of authenticity plus a unique serial number tying your exact stone to its paperwork. That documentation matters — it is the difference between being told a diamond is D color and VVS clarity and being able to prove it. If you want to understand what the grading bodies actually measure, our IGI vs GIA certification guide is the place to start.
A real diamond, grown instead of mined
Lab-grown diamonds are chemically, optically, and physically identical to mined diamonds — carbon crystallized to a 10 on the Mohs scale, the hardest gemstone there is. The Feyra’s pear-cut stone measures approximately 7.0 x 10.0 mm and weighs roughly 1.7–2.2 carats (each stone is matched to the setting, so the exact weight varies slightly within that range). The skeptic’s question is answered plainly in are lab-grown diamonds real diamonds, and the deeper science lives in our complete lab-grown diamond guide. More certified designs wait among our lab-grown diamond engagement rings.
Blue sapphire, in good company
On either shoulder of the diamond sit lab-grown blue sapphires — genuine corundum, 9 on the Mohs scale, in the deep celestial blue long associated with wisdom, loyalty, and enduring love. Diamond and sapphire is one of jewelry’s oldest partnerships, and the yellow gold setting warms both stones beautifully. If blue speaks to you, our sapphire engagement rings collection carries the theme further.
Three karats of solid yellow gold
The band is solid yellow gold in the karat you choose from the drop-down menu: 10K for maximum hardness at the friendliest price, 14K for the classic balance of warmth and everyday strength, or 18K for the richest gold content and deepest color. Our 10K vs 14K vs 18K karat guide compares all three, and the wider world of yellow gold jewelry shows how well this metal keeps company. Different gemstone options are available on request — contact us for a custom quote.

Sizing & care
Pick your size from the drop-down menu — half and quarter sizes are listed, and larger or smaller sizes are available on request. Jewelers’ sizing tools can disagree by up to half a size, so a quick pass through our ring size guide before ordering is time well spent.
Diamond and sapphire are the two hardest gemstones in common use, so this ring asks very little: warm water, mild soap, and a soft brush now and then, plus separate storage so it cannot scratch softer pieces. It ships in a free luxury ring box with its certificate, and an optional appraisal can be added from the drop-down menu.
Frequently asked questions
Is a lab-grown diamond a real diamond?
Yes — completely. Lab-grown diamonds are pure crystallized carbon with the same chemical, optical, and physical properties as mined diamonds, including a perfect 10 on the Mohs hardness scale.
What does the IGI certification cover?
The International Gemological Institute independently grades the center diamond’s quality characteristics. Your ring also includes a certificate of authenticity and a unique serial number linking your exact stone to its documentation.
Why is the carat weight given as a range?
Each pear-cut diamond is matched to the ring’s 7.0 x 10.0 mm setting, so the exact weight varies slightly from stone to stone — roughly 1.7 to 2.2 carats. The face-up size on the finger stays consistent.
What do D color and VVS clarity mean?
D is the top of the diamond color scale — fully colorless. VVS means inclusions so minute they are very, very slight even under 10x magnification. In plain terms: an icy, exceptionally clean diamond.
Are the blue sapphire accents genuine sapphires?
Yes. They are lab-grown blue sapphires — real corundum, chemically identical to mined sapphire, rated 9 on the Mohs scale and well suited to daily wear.
Will a lab-grown diamond test as a diamond?
Yes. Because a lab-grown diamond is a diamond, it reads as one on diamond testers — and unlike a simulant, it carries grading paperwork to match.
Which karat of yellow gold should I pick?
10K is the hardest and most affordable, 14K is the most popular balance of color and durability, and 18K carries the richest hue and highest gold content. All three are solid gold throughout.
Can I choose different gemstones for this design?
Yes — different gemstone options are available. Contact us with what you have in mind and we will prepare a custom quote.
Is there a matching wedding band?
Yes — the Feyra is also sold as a complete two-piece set that includes the matching band, listed separately in our shop.
How long does crafting take?
Each ring is made to order by hand; please allow 3–5 weeks. Requested modifications can extend the timeline and adjust the price.
Can the band be engraved?
Yes — complimentary engraving of up to 16 characters is included with every ring.
How do I get the sizing right?
Measure with our ring size guide before ordering. Sizers and mandrels vary between jewelers, so a measured size can differ by up to half a size from shop to shop.
How should I care for this ring?
Clean it with warm water, a drop of mild soap, and a soft brush, then pat dry. Store it apart from other jewelry. Diamond (Mohs 10) and sapphire (Mohs 9) make this one of the most wear-resistant rings you can own.
Can I add a formal appraisal?
Yes — select the optional appraisal from the drop-down menu. Note that the appraisal cost is non-refundable once the work has been performed.
✨ Production time
Every ring on this page is cast, set and finished for your order. Nothing is taken from stock.

Please note: upgraded shipping speeds up transit only — it does not shorten the 3–6 week production time. Transit estimates begin the day your ring ships, not the day you order, and can vary with carrier delays. Shipping fees are non-refundable.
🌍 International
We ship worldwide with DHL. Live rates for your address are calculated at checkout — usually DHL Express Worldwide, with DHL eCommerce Parcel Standard also offered to some destinations as a slower, lower-cost option.
For many countries, duties and taxes can be prepaid at checkout for a smoother delivery — if prepaid, no additional fees are due on arrival. Customs fees are set by your country and are non-refundable once the order has shipped.
Every order ships fully insured and requires a signature. Full details on our Shipping & Delivery page.
Engraving is cut into the inside of the band, so it stays between the two of you.
AVAILABILITY
Engraving is offered on most — though not all — designs. If it is available for this ring, an engraving field appears with the options above.
CHARACTER LIMITS
Limits depend on the width and design of the band. Spaces count toward the total.
• Women’s rings: up to 16 characters
• Men’s rings: up to 25 characters
FONT AND SYMBOLS
Standard engraving is complimentary and set in Arial, chosen because it stays legible at very small sizes. These symbols are included at no extra cost:
♥ ♡ ☾ ✩ ★ ✿ ♬ ♯ • ■
Custom fonts, or symbols outside this selection, are available for $25. For a logo or bespoke design, email us an SVG file before you order so our team can confirm it will engrave cleanly. Very fine or highly detailed artwork may not suit narrow or delicate bands — we will tell you before we proceed rather than after.
HOW TO ORDER
• Choose your ring, metal and size
• Enter your text in the engraving field
• For a custom font or symbol, contact us before ordering
• Check your wording carefully before checkout — we engrave exactly what is entered

Frequently Asked Questions
Every ring on this page is made in solid gold or platinum — never plated, never gold-filled. Solid gold comes in 10K, 14K and 18K across yellow, white and rose; our platinum is 95% pure, naturally hypoallergenic, and white the whole way through. Available metals vary by design and are listed in the selector above. Our Precious Metal Guide explains how each one wears.
Side by side and brand new, the two look almost identical. The difference shows up over years of wear.
White gold is a gold alloy finished with rhodium for brightness. It sits lighter on the hand and costs less, and the rhodium finish is refreshed every few years to keep it crisp.
Platinum is white all the way through, so there is no finish to renew. It is around 40% denser — noticeably weightier — and over time develops a soft matte patina that many people prefer. It can be polished back to a high shine whenever you like.
Our Platinum vs Gold guide compares durability, cost and upkeep in full.
Solid gold is gold throughout — alloyed for strength, but the same metal at the surface as at the core. Gold vermeil is sterling silver with a layer of gold applied over it, which thins with wear and needs replating to stay bright. Rings on this page are solid gold or platinum only. Our Precious Metal Guide sets out where each makes sense.
Neither tarnishes. Gold and platinum are two of the most stable metals used in fine jewelry, and both hold their color indefinitely. Platinum does develop a satin patina as it is worn — that is surface texture rather than damage, and it polishes out at any time. Warm water, mild soap and a soft brush is all either metal asks for; see our Jewelry Care Guide.
Nothing on this page is pulled from a shelf. Each solid gold and platinum ring is cast, set and finished for your order, which takes 3 to 6 weeks depending on the design — pavé settings, custom sizing and engraving sit at the longer end. Shipping is added once your ring is finished, and paying for faster shipping speeds up transit only — it does not shorten production. Full timings are on our Shipping & Delivery page.
Use the Size Chart linked beside the Add to Bag button, or our full Ring Size Chart. Because these rings are made to order, we cut your size from the start rather than resizing a stock band — so measure carefully. Your first resizing is free if it is still not right. Most designs can be adjusted, though eternity bands and rings with stones set the whole way around usually cannot.
On most designs, yes — if engraving is available for this ring, a text field appears with the options above. Standard engraving is complimentary: up to 16 characters on women’s rings and 25 on men’s, set in Arial, with a small selection of symbols included. Custom fonts and symbols are $25 and are arranged before you order. See the Engraving page for what is possible. Engraved rings are final sale.
Returns and exchanges are accepted within 14 days of delivery on unworn rings in original condition. Because solid gold and platinum rings are made to order, they are subject to a restocking fee, and engraved pieces are final sale. Full terms are on our Returns & Refunds page. Every ring is also covered by our lifetime warranty against manufacturing defects.
