Any piece of diamond jewellery you can describe, made on our bench.

ProJewel is the bespoke side of the operation. Engagement rings, eternity bands, tennis bracelets, tennis necklaces, pendants, perfect-pair stud earrings, drop earrings, halos, three-stones, signet rings, anniversary pieces, anything fine and set with diamonds. We can source the centre stones, the calibrated sides, the metal, and the design to spec. Designed with the buyer, manufactured in Bedfordview, set with stones polished at Procut DCW. One roof, one hand from rough to ring. If you can sketch it, we can make it.

Concierge house, not a catalog

Recent commissions. Most pieces are made to brief.

Most ProJewel pieces start as a brief, not a catalog click. A stone you saw, an heirloom you want reset, an engagement ring built around a centre we cut for you. Designed and made on the Bedfordview bench by the same hand from rough to ring. The pieces below are recent work, not the limit of what we make.
