Starry Night Coffin Kite Engagement Ring Set in 14K Solid Rose Gold

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

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.

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).
