The in-house advantage

Cut to the mount

Stones are cut and calibrated to fit the setting, not sorted to fit it — tighter tolerances and less waste.

Colour to a master

Colour is matched to a master stone retained for your account, so repeat orders stay consistent.

Treatment disclosed

Every stone is genuine, with any treatment stated plainly beside it — no surprises for your buyer.

Gemstone cutting service

Because the stone department is ours, we also cut and calibrate to order — useful when a design needs a size or shape that is not stocked. Send the specification with your enquiry and we will quote the cutting alongside the piece.
