This coffin engagement ring set puts an unusual, elongated coffin-cut center front and center: a deep midnight-blue galaxy sandstone that glitters with tiny points of copper light like a starfield, matched to a coordinating band with kite-cut accents — a two-piece set in warm solid 14K rose gold. The bold coffin silhouette makes it a striking, alternative-bridal choice for lovers of the night sky.
The coffin cut
The coffin (or elongated hexagon) cut is one of the boldest alternative shapes in bridal jewelry — angular, geometric, and unmistakably modern-gothic. Paired with the cosmic blue sandstone, it reads like a shard of night sky. If you're drawn to unconventional bridal styles, our non-traditional engagement ring guide is a great starting point, with more in our nature-inspired engagement rings and sapphire engagement rings.
The starry-night stone — honest disclosure
The center is blue galaxy sandstone, also called blue goldstone — a man-made art glass with tiny copper crystals suspended in deep cobalt glass to mimic a starfield. We're upfront that it's man-made, not a natural mined gem; it was created centuries ago specifically to capture the look of the night sky, and nothing natural quite reproduces that glittering effect. Because sandstone is softer (about 7 Mohs), we offer a free upgrade to a natural blue sapphire center at no additional cost for maximum durability — just leave a note at checkout.
A two-piece set
Engagement Ring
Coffin-cut galaxy sandstone center (7×11mm, ~1.6ct) in solid 14K rose gold.
Matching Band
Coordinating band with kite-cut sandstone and moissanite accents, designed to nest against the engagement ring. Matching solid 14K rose gold.
Sold as a two-piece set; each ring can also be worn on its own.
Choose your metal
This set is solid gold — the metal itself, not plating or vermeil over a base metal. Choose your karat from the drop-down; each is real solid gold, and the warm rose tone glows against the deep cosmic blue. The color is permanent: it won't wear off and won't turn your skin green.
- 10K rose gold — the most affordable and hardest-wearing option, great for everyday durability.
- 14K rose gold — our most popular choice, balancing durability, purity, and value.
- 18K rose gold — a higher gold content for a richer, warmer tone and more luxurious feel.
Not sure which to pick? Our 10K vs 14K vs 18K gold guide breaks down the trade-offs. White or yellow gold available on request.

Sizing & care
Galaxy sandstone is softer (~7 Mohs) and prefers gentle care — avoid hard knocks, harsh chemicals, and ultrasonic or steam cleaners; clean with a soft, barely-damp cloth. (The optional natural sapphire center is far harder at 9 Mohs.) Both rings should be ordered in the same size; please reference our sizing guide before ordering. An optional written appraisal can be added from the drop-down menu (non-refundable once completed).
Coffin engagement ring FAQs
What is a coffin cut?
An elongated, angular hexagon shape — one of the boldest alternative bridal cuts, with a modern-gothic edge. Here it frames the cosmic blue sandstone like a shard of night sky.
Is the galaxy sandstone a natural stone?
No — it's man-made blue goldstone (art glass) with copper crystals suspended to mimic a starfield. We disclose this openly. A free natural blue sapphire swap is available for more durability.
Can I make the center more durable?
Yes — we offer a free upgrade to a natural blue sapphire center (9 Mohs) at no additional cost. Just leave a note at checkout.
Is this real solid rose gold?
Yes. The set is solid rose gold throughout in your chosen karat (10K, 14K, or 18K) — the metal itself, not plating or vermeil. The color is permanent, won't wear off, and won't turn skin green.
How long does it take to make?
Made to order — please allow about 2–3 weeks. Requested modifications may adjust the timeline, and we'll confirm everything before production begins.
Which metal should I choose?
All karats are real solid gold. 10K is the most affordable and hardest-wearing, 14K is our most popular all-round choice, and 18K has a higher gold content for a richer, warmer tone. See our 10K vs 14K vs 18K guide for details.

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 Find my ring size link beside the Add to Cart 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.
