Coffin Cut Alexandrite & Moonstone Engagement Ring in 14K White Gold

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. Available in solid 14K white gold (this listing default), 14K yellow gold, or 14K rose gold on request; 18K upgrades available at additional cost.

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.

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.

How to wear it

• Engagement ring — for gothic, alternative, witchy, or dark-academia couples who want a ring with genuine symbolic identity in heirloom solid gold construction
• Gothic / dark-romance heirloom — the coffin cut is the signature gothic bridal shape; "'til death do us part" rendered in stone and solid gold
• June birthstone gift — both alexandrite and moonstone are June birthstones; two of June's three stones in one heirloom ring
• Promise or anniversary ring — the substantial ~2.1ct center and solid gold construction suit major milestone occasions
• Halloween / autumn season piece — the coffin symbolism makes it a popular Halloween-season proposal choice
• Color-change conversation piece — the daylight-to-evening shift makes this a ring people notice twice

For an engagement pairing, the elongated coffin center suits a chevron or V-contour wedding band that follows the tapered base, or a plain band that lets the silhouette stand alone. Match in 14K white gold for a unified stack.

Specifications

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.
