THE COLLECTOR PRACTICE
One of a Kind
One stone. One jewel.
Every piece in One of a Kind begins with a single natural gemstone, chosen for its colour, its light and the small irregularities that make it unrepeatable: a Paraiba tourmaline with neon depth, a Colombian emerald with its own garden inside, a bicolor sapphire that shifts from one shade to the next, an alexandrite that changes with the light. The setting is then drawn for that stone alone.
Many of these rings are made to be worn as engagement rings. Each is made to order in 14K or 18K gold, typically in 3–5 weeks. When a jewel finds its owner, it moves to the Archive.
Looking for a permanent design instead? Explore Heirloom & Engagement Rings or read our bicolor sapphire engagement ring guide.
