Wear & styling

The heart sapphire is the centerpiece, while the diamond stations carry balanced sparkle around the neckline. Made for gala evenings, milestone celebrations and heirloom gifting; pair it with sapphire earrings or a diamond bracelet.

Why an unheated sapphire matters

Unheated sapphires are untreated, so their color is entirely natural, which makes them rarer and more sought after by collectors.

Care

Clean gently with warm water, mild soap and a soft brush. Avoid ultrasonic cleaners and harsh chemicals, and store flat in a soft-lined box. Explore more in our Diamond Heart Jewelry collection.
