The Cosmos begins with the stone. Each pendant in this series is built around its own individual Australian diamond — the 18K gold setting shaped to the exact dimensions of that single gem, so no two are precisely alike.

This one carries a sparkling white diamond, untreated and unheated, sourced from iconic Australian Argyle mine.

The setting is handcrafted in our Sydney workshop, open petals, wavy-edged and light-catching, built by our master jewellers to hold this stone and no other.
