Crescent Moon Starry Night Engagement Ring Set in 14K White Gold

This crescent moon starry night ring set pairs a sparkling starry-night galaxy center — deep blue scattered with tiny points of light like a night sky — with a delicate crescent moon detail, matched to a coordinating band, all in cool white gold. A celestial, fantasy-inspired two-piece set for anyone whose love story is written across the stars.

About the starry-night center stone

Honesty first: the sparkling blue starry-night center is a blue goldstone (often called blue sandstone or galaxy stone). It's a man-made material — a richly colored glass filled with tiny sparkling mineral flecks that catch the light like a field of stars (about 7–7.5 Mohs). It's not a natural gemstone, so it deserves gentle care. Because we'd rather set the right expectation than oversell, we offer a no-cost upgrade: if you'd prefer a natural, harder, more durable center, we can substitute a blue sapphire instead — just leave a note at checkout. If you love unconventional bridal styles, our non-traditional engagement ring guide and blue gemstones guide are great reads.

Choose your metal & karat

Select your metal and karat from the drop-down. Every option is solid gold (or solid platinum) throughout — the metal itself, never plating or vermeil over a base metal, so the color is permanent, won't wear off, and won't turn your skin green. Karat sets the gold's purity and price: 10K is the most durable and affordable, 14K is our most popular balance of rich color and everyday strength, and 18K is the purest, warmest gold. Platinum is a naturally white, hypoallergenic, and exceptionally durable premium metal. Our 10K vs 14K vs 18K gold karat comparison guide walks through how they differ.

Why solid gold & platinum

Whichever option you choose, this set is solid metal throughout — not plating or vermeil over a base metal. The cool white heightens the midnight-blue, star-flecked center, and the color is permanent: it won't wear off and won't turn your skin green.

Sizing & care

The starry-night galaxy center is a glass-based material and softer than natural gemstones, so treat it gently: avoid hard knocks, remove the ring for rough hands-on work, keep it away from harsh chemicals, and clean only with a soft, dry or barely damp cloth — no ultrasonic or steam cleaners. If you want a tougher, natural center, choose the blue sapphire substitution at checkout. 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).
