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 solid 9ct, 14ct and 18ct gold (never plated) — yellow, white and rose. 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. As the manufacturer, we make every finished piece in our own workshops, and qualifying finished pieces are 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 IGI grading, so your customer receives clear documentation of the stone they are buying.
What is a lab-grown diamond?
A diamond created in controlled laboratory conditions. It has the same physical, chemical and optical properties as a mined diamond, at a lower price point.
Are the diamonds graded?
Qualifying stones are supplied with independent IGI grading — the specific report is confirmed at the point of quote.
Can I order loose stones as well as finished pieces?
Yes. We supply both loose lab-grown diamonds and made-to-order finished jewellery.
Can I order a single piece?
Yes. After your opening order there are no minimums — order one piece or stone at a time.
Are finished pieces hallmarked?
Qualifying finished pieces carry a full UK Assay Office hallmark before dispatch. Items below the legal weight threshold are not required to be hallmarked.
