Her Ring
Solid 925 sterling silver finished in luxurious 14k yellow gold vermeil, cradling a 7 x 10 mm (approx. 1.7 ct) coffin-cut lab-grown blue sapphire framed by natural black onyx. Slim 1.7 mm band.
His Ring
An 8 mm brushed-and-hammered black tungsten carbide band inlaid with crushed sapphire and yellow gold leaf, with a comfort-fit interior — rugged, refined, and quietly spectacular.
The sapphire at its heart
Sapphire has long stood for wisdom, loyalty, and truth, which is why it has crowned romantic jewelry for centuries; you can read the full story in our sapphire meaning guide. Her center is a lab-grown blue sapphire — a real sapphire, grown for vivid, consistent color — cut in a dramatic coffin shape. As the September birthstone, it makes this set a meaningful choice for September couples and anniversaries.
The black onyx & blackened band
Her sapphire is framed by natural black onyx, a classic deep-black stone prized for the sense of strength and protection it carries — explored in our black onyx meaning guide. His band answers it with a rich blackened finish and a glowing inlay of crushed sapphire and gold leaf, tying the two rings together in one moody, romantic palette.
Metals & everyday wear
Her ring is solid 925 sterling silver finished with 14k yellow gold vermeil for a warm gold glow; his is durable black tungsten carbide with a comfort-fit interior. Both are hypoallergenic and nickel-free and built for everyday wear, and you will find companion pieces among our gold couples rings. Her ring can be upgraded to solid gold on request.
