A deep, dramatic blue sapphire couples ring set in warm rose gold. Her ring centers a coffin-cut lab-grown midnight-blue sapphire; his is a tungsten band inlaid with crushed blue sapphire. The elongated coffin cut gives a classic gemstone a striking, gothic-modern edge — a his-and-hers pair with real presence.

A coffin-cut sapphire couples set
This is the coffin-cut, rose gold sapphire pairing — sharper and more dramatic than a round or oval, joined by his crushed-sapphire band. Ideal for gothic-glam or non-traditional weddings, alternative engagements, promise rings, or a September-birthstone anniversary gift.
Her Rings
Solid 925 sterling silver with 14K rose gold vermeil, centered on a coffin-cut lab-grown blue sapphire with simulated diamond accents. Slim 1.7 mm each.
His Ring
An 8 mm tungsten carbide band inlaid with crushed blue sapphire, sealed with a protective coating.
Midnight blue sapphire
Her center is a lab-grown blue sapphire in a deep midnight blue — real sapphire, created in a lab and chemically identical to a mined stone. Sapphire is a 9 on the Mohs scale, so it wears beautifully every day, and it's the September birthstone, a classic symbol of loyalty and wisdom.
What is a coffin cut?
A coffin cut is an elongated hexagonal shape with angled ends — the same geometry as a kite cut, styled for a bolder, gothic look. It gives the sapphire a long, architectural silhouette.
Lab-grown vs simulated — clearly
Her center is a lab-grown sapphire; the accents are simulated diamonds (cubic zirconia), and his band uses crushed blue sapphire. We keep lab-grown and simulated clearly distinct so you always know what's in your ring.
Metals
Her rings are 14K rose gold vermeil over solid 925 sterling silver; his is tungsten carbide, hard and scratch-resistant. Both hypoallergenic and nickel-free. Her ring is available as a solid gold custom upgrade.
