Request the Lab-Grown Trade PackMeet the demand without the outlay
More and more customers ask for lab-grown diamonds — they offer a larger stone at a lower price point than mined equivalents. But carrying a lab-grown range means capital tied up in stock and stones you may never sell. Our made-to-order model lets you offer the full category from a sample or a design render, with each piece built only once your customer has committed.
Loose stones and finished jewellery
Lab-grown diamond engagement styles, eternity and half-eternity bands, stud and drop earrings, pendants and tennis bracelets — in 9ct, 14ct and 18ct yellow, white and rose gold, plus platinum. Loose lab-grown stones supplied across a full range of carat weights, colours and clarities. Lab-grown diamonds have the same physical and optical properties as mined diamonds, and every qualifying finished piece is UK hallmarked before dispatch.
From spec to finished piece
The margin logic
A lower stone cost means an accessible retail price and a healthy margin at the same time. We supply suggested RRPs alongside trade prices so you can quote with confidence.
Graded & traceable
Qualifying lab-grown diamonds are supplied with independent laboratory grading, so your customer receives clear documentation of the stone they are buying.
