Galaxy Sandstone (Starry Night) Engagement Ring Set in 14K Solid Rose Gold
This galaxy sandstone ring set centers a coffin-cut galaxy stone — deep blue scattered with tiny points of light like the night sky — accented with moissanite and matched to a coordinating band, in warm solid rose gold. Now available in your choice of karat. A bold, cosmic two-piece set for a love story written in the stars.
Choose your karat
This set is made in solid rose gold — the metal itself, not plating or vermeil over a base metal. Use the drop-down to choose the karat that suits you:
10K Rose Gold
The most affordable and the hardest-wearing of the three karats — a great everyday choice, with a soft blush tone.
14K Rose Gold
Our most popular pick: the classic balance of durability, rich rosy color, and value.
18K Rose Gold
The highest gold content we offer — the warmest, most saturated blush and a true heirloom feel.
Why rose gold suits it
The warm blush metal glows against the midnight-blue, star-flecked center. White or yellow gold are available on request.
Higher karat means more pure gold and a warmer tone; lower karat is harder and more budget-friendly. Not sure which is right? Our 10K vs 14K vs 18K gold comparison guide walks through durability, color, and price so you can choose with confidence.
About the galaxy center stone
Honesty first: the sparkling blue coffin 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 6–7 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. Our non-traditional engagement ring guide and blue gemstones guide are great reads.

Sizing & care
The galaxy center is a glass-based material and softer than natural gemstones, so treat it gently: avoid hard knocks, 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).
