The heart at the centre isn't one stone, but three individual sapphires, custom-cut to fit together. This creates a different kind of reflection than a single gem. It’s a small detail you notice when you look closely, framed by a complete halo of diamonds.

A delicate, 16-inch platinum chain holds a small heart pendant. The heart itself is formed from three deep blue sapphires. A continuous halo of sixteen small, round diamonds frames the sapphires, creating a bright contrast against the blue. The whole pendant is quite small, measuring 7mm by 8mm, and hangs from a simple, polished bail.

We made this from PT900 platinum, which is 90% pure platinum. It’s naturally hypoallergenic and has a satisfying weight that you don't get with other white metals. Its bright white colour won't fade or tarnish over time. The three central sapphires are natural, totalling 0.190 carats. They're encircled by sixteen natural diamonds, which add up to 0.070 carats.

This isn't a large pendant. At just 8mm tall, it's designed to sit right at the collarbone on its 16-inch chain. It’s a classic heart halo, but the smaller scale gives it a quieter feel. The way the three sapphires are pieced together in the centre is an unusual construction.
