When the Right Stone Doesn't Exist Yet
Some requests are best answered by cutting rather than searching. Where rough or a recut candidate offers a better route to your specification, we can bring it into our own workshop — see Cutting Services.
"Sourcing is patience and network. The stone a client describes usually exists somewhere — the work is knowing who has it, and being trusted enough to be shown it first."— Brian Gavin, Fifth-Generation Diamantaire
