Sapphire and Diamond Ring Styles

For an engagement ring, a single blue sapphire in a halo or vintage art deco setting gives a classic, regal look, with oval, cushion, princess and emerald cuts to choose from. For a wedding or anniversary band, rainbow eternity bands set rows of colored sapphires in round, princess, baguette, emerald or marquise shapes, often bordered with pave diamonds. Bridal sets and promise rings round out the range. Explore more color in the full rainbow collection, or compare all-diamond styles in our lab diamond eternity rings.

How to Choose a Sapphire and Diamond Ring

Start with the color. Blue is the classic choice, while rainbow bands suit anyone who loves bold, playful jewelry. Then choose a metal: white gold keeps blues crisp, while yellow and rose gold warm the look. Sapphire rates 9 on the Mohs scale, so it is a practical stone for regular wear.
