The solid 14K white gold version of our coffin-cut alexandrite ring — a substantial 7×10mm color-change alexandrite at the center, cut in the elongated coffin silhouette that defines gothic and dark-romance bridal, flanked by paired moissanite clusters and a glowing marquise rainbow moonstone at each shoulder. Built entirely in solid 14K white gold (no plating, no sterling core), with every stone in the ring real: lab-created alexandrite, natural rainbow moonstone, and real moissanite. The alexandrite shifts color with the light — teal-blue in daylight, violet-purple under warm evening light — while the moonstones flash their lunar glow at the edges. Gothic structure, celestial shimmer, heirloom construction: built to be worn for a lifetime and passed down.

The Color-Change Effect
Alexandrite is famous for one thing above all: it changes color with the light. In daylight or cool fluorescent light, the stone reads teal to blue-green; under incandescent bulbs, candlelight, or warm evening light, it shifts toward violet, purple, and reddish-plum. The shift is real and dramatic — the same ring reads as two different stones depending on where you are. Our guide on how alexandrite shifts color explains the science behind the effect if you want to go deeper.
This is lab-created alexandrite: real color-change alexandrite material (chrysoberyl with the same chromium-driven color shift as natural alexandrite, Mohs 8.5) grown in controlled lab conditions — which is what makes a stone of this size and shift quality possible at all. Natural alexandrite above 2 carats is one of the rarest and most expensive gems on earth.
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 doesn't need replating, doesn't wear through, and holds resale and inheritance value in a way that lighter constructions don't.
This is the meaningful difference between this version and the sterling silver version of the same design — and on this version, the cluster accents are upgraded from CZ to real moissanite, so every stone in the ring is real. The cool bright white gold suits the ring's palette perfectly: teal-violet alexandrite, blue-flash moonstone, white-fire moissanite. Choose 10K, 14K, or 18K white gold, or platinum, from the drop-down; 14K yellow or rose gold on request. Each option is genuinely solid white metal — 10K is the hardest and most affordable, 14K the most popular all-rounder, and 18K carries the richest gold content, while platinum is naturally white, the densest of the group, and hypoallergenic. If you're weighing the karats, our 10K vs 14K vs 18K karat guide breaks down the trade-offs.
About the coffin cut
The center stone is cut in a coffin shape — an elongated hexagonal silhouette with angled shoulders tapering toward the base, echoing the outline of a classic casket. The coffin cut has become the signature shape of gothic, dark-romance, and alternative bridal jewelry: structured and geometric like a kite or hexagon cut, but with an unmistakable dark-symbolic identity that no other shape carries.
Beyond the symbolism, the coffin cut is a genuinely flattering shape — the elongated proportions (7×10mm here) stretch the stone vertically on the finger, the step-cut facets show off the alexandrite's color depth across long clean planes, and the angular geometry catches the color shift in distinct flashes as the hand moves. Symbolically, the coffin in gothic romance tradition reads as "'til death do us part" made literal — eternal commitment, love beyond death, and the beauty found in darkness. In solid white gold, the gothic statement gains heirloom permanence: a ring meant to outlast its wearer, which is rather the point.
About the lab-created alexandrite center
The center stone is lab-created alexandrite — real color-change alexandrite material (chrysoberyl), grown in controlled laboratory conditions, with the same chemistry, the same Mohs 8.5 hardness, and the same chromium-driven color-change behavior as natural mined alexandrite. The only difference is origin — and at this size, origin is everything: natural alexandrite above 1 carat is among the rarest gems in the world, with fine 2-carat natural stones commanding five-figure-plus prices. Lab creation makes the full-size, full-shift alexandrite experience accessible, and pairs it here with construction worthy of it. It's one of the boldest pieces in our collection of alexandrite engagement rings.
At Mohs 8.5, alexandrite is one of the most durable colored center stones available — harder than aquamarine, morganite, moonstone, or opal — well suited to daily wear for a lifetime.
About the rainbow moonstone accents
The marquise accent stones at the outer shoulders are natural rainbow moonstone — real moonstone displaying adularescence, the floating blue-white glow that moves across the surface of the stone as it catches light. "Rainbow" moonstone is the trade name for the variety with strong blue-to-multicolor flash on a semi-translucent body. Each moonstone's glow pattern is natural and slightly unique, so your ring's lunar shimmer is one of a kind.
The moonstones do real aesthetic work in this design: their soft glow balances the sharp gothic geometry of the coffin cut, pulling the ring toward celestial and witchy territory — the coffin's dark structure framed by moonlight. Note that moonstone is softer than the alexandrite center (Mohs 6–6.5), so the accents appreciate gentle treatment.
About the moissanite cluster accents
The paired round stones clustered beside the center are real moissanite — silicon carbide, a distinct gemstone in its own right (not a diamond, not a simulant), with more fire (rainbow flash) than diamond and exceptional durability at Mohs 9.25. On the sterling silver version of this design these accents are CZ; at the solid gold tier they're upgraded to moissanite, so every stone in the ring is real — center, shoulders, and clusters. The moissanite's white fire bridges the alexandrite's color shift and the moonstones' blue glow.
Both June birthstones in one ring
A detail that makes this ring uniquely meaningful as a gift: alexandrite and moonstone are both June birthstones (June is one of the few months with multiple birthstones — alexandrite, moonstone, and pearl). This ring carries two of the three June stones in a single design — for June birthdays, June anniversaries, or June-born partners, the symbolism is doubled, now in heirloom solid gold.

Sizing & care
Available in sizes 3–10 (US). Larger and smaller sizes are available on request — priced upon request. 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.
The alexandrite center (Mohs 8.5) and moissanite clusters (Mohs 9.25) are highly durable and handle daily wear well. The rainbow moonstone accents are softer (Mohs 6–6.5) and appreciate gentler treatment — avoid impact on hard surfaces, harsh chemicals, ultrasonic and steam cleaners, and sudden temperature changes across the whole ring. Clean with warm water and a soft cloth or soft brush. Solid 14K white gold doesn't need replating and holds its tone indefinitely; a soft jewelry cloth keeps it bright. Remove the ring before swimming, gardening, or heavy work, and store it separately so the prongs and moonstone accents don't catch on other pieces.
Frequently asked questions
Does the alexandrite really change color?
Yes — the color change is the stone's defining feature. In daylight or cool fluorescent light, the alexandrite reads teal to blue-green; under incandescent bulbs, candlelight, or warm evening light, it shifts toward violet, purple, and reddish-plum. The shift is caused by chromium in the crystal absorbing different wavelengths depending on the light source. The same ring genuinely reads as two different stones depending on the lighting.
Is the alexandrite natural or lab-created?
Lab-created — real color-change alexandrite material (chrysoberyl) with the same chemistry, the same Mohs 8.5 hardness, and the same chromium-driven color shift as natural mined alexandrite, grown in controlled lab conditions. We're upfront about this because at this size, origin matters enormously: natural alexandrite above 1 carat is among the rarest gems in the world, and a fine natural 2-carat stone would cost well into five figures. Lab creation is what makes the full-size, full-shift alexandrite experience accessible.
summary>What's the difference between this and the sterling silver version?
Two meaningful upgrades. Metal: this version is solid 14K white gold throughout — built to last a lifetime, never needs replating, holds resale and inheritance value — versus the rhodium-finished sterling silver version. Accent stones: the paired cluster accents are upgraded from CZ to real moissanite, so every stone in this ring is real (lab-created alexandrite, natural rainbow moonstone, real moissanite). Plus this version is made to order with full customization: engraving, metal and karat choice (10K, 14K, or 18K white gold, or platinum), and optional appraisal. The silver version is the accessible entry point; this is the heirloom tier.
What is a coffin cut?
An elongated hexagonal cut with angled shoulders tapering toward the base, echoing the outline of a classic casket. It's become the signature shape of gothic, dark-romance, and alternative bridal jewelry — structured like a kite or hexagon cut, but with a dark-symbolic identity no other shape carries. The elongated proportions flatter the finger and the broad step facets show off the alexandrite's color shift especially well.
Are the moonstones real?
Yes — the marquise accents at the shoulders are natural rainbow moonstone, displaying genuine adularescence (the floating blue-white glow that moves across the stone as it catches light). Each moonstone's flash pattern is natural and slightly unique.
Are the small white stones diamonds?
They're real moissanite — silicon carbide, a distinct gemstone in its own right, not a diamond and not a simulant. Moissanite has more fire (rainbow flash) than diamond and exceptional durability at Mohs 9.25. If you'd prefer lab-grown or natural diamond cluster accents, message us before ordering for a custom quote.
Why is this called a June birthstone ring?
June is one of the few months with multiple birthstones — alexandrite, moonstone, and pearl. This ring carries two of the three: the alexandrite center and the rainbow moonstone accents. For June birthdays, June anniversaries, or June-born partners, the birthstone symbolism is doubled in a single ring.
Is this ring solid gold or gold plated?
Solid 14K white gold throughout — no plating, no gold-filled construction, no sterling silver core, no rhodium finish layer. The entire ring is white gold alloy. Built to last a lifetime, never needs replating, holds resale and inheritance value.
How big is the center stone?
7.0 × 10.0 mm coffin cut, approximately 2.1 carats. The elongated silhouette wears large on the finger — at a full centimeter long, this is a genuine statement-presence center stone.
How durable is the ring for daily wear?
The alexandrite center (Mohs 8.5) and moissanite clusters (Mohs 9.25) are among the more durable stones available and handle daily wear well. The rainbow moonstone accents are softer (Mohs 6–6.5) and appreciate gentler treatment: avoid hard knocks, harsh chemicals, and ultrasonic cleaners. With sensible care the ring wears well daily, but it needs slightly more attention than an all-hard-stone ring because of the moonstone accents.
Can I get this in yellow or rose gold, or 18K?
Yes — choose 10K, 14K, or 18K white gold, or platinum, right from the drop-down; 14K yellow or rose gold on request. 10K is the hardest and most affordable, 14K the most popular all-rounder, 18K the richest in gold content, and platinum is naturally white, densest, and hypoallergenic. White gold preserves the cool moonlit palette; yellow or rose gold gives a warmer contrast against the teal-violet alexandrite. Message us before ordering.
How does engraving work?
Complimentary engraving up to 16 characters is included. Specify the text at checkout or message us before ordering. Engraving is interior (inside the band), the standard placement for engagement ring engravings.
How long until my ring ships?
Made to order — please allow 2–6 weeks for it to be handmade for you. Requested modifications (different metal or karat, engraving, custom sizing, accent upgrades) are subject to revised production timelines and pricing. We'll confirm timing when your order is placed.
Should I add the appraisal?
The optional appraisal is recommended if you plan to insure the ring or want an independent valuation document. Most insurance providers require a written appraisal to schedule a ring on a jewelry policy. The appraisal cost is non-refundable once the work has been performed, so add it at checkout only if you know you'll use it.
Are the stones ethically sourced?
Yes. Lab-created alexandrite and moissanite have no mining footprint and are fully traceable from controlled-lab origin. Natural rainbow moonstone is ethically sourced.
What's included in the box?
The ring, a free luxury velvet jewelry box, and a care card. Free USA shipping.
