LOOSE DIAMONDS
Natural and lab-grown diamonds from 0.05 ct, calibrated to exact length, width and depth, in D–I colour and IF–VS2 clarity. Stones of 1 ct and above come with IGI reports (lab-grown, to 10 ct) or GIA/HRD reports (natural, to 5 ct).
WAX JEWELLERY MOULDS
Precise wax models for lost-wax casting, made to the exact dimensions of each design. They give jewellers and workshops a faithful master before the metal is cast, so the finished piece holds its stones exactly as intended.
Wax moulds, loose diamonds and custom jewellery under one roof: we take care of the whole journey, from first enquiry to finished piece.

OUR STORY
Twenty-two years in diamonds, built on one principle: help every client make the right choice.
RKD Diamonds was founded by Rupak Kumar Agrawal, who has spent 22 years in diamond sales. Before starting RKD, he was one of the top salesmen at his previous company and represented it at trade exhibitions across Southeast Asia.
That experience shapes everything we do. Rupak knows stones, markets and buyers in depth, and he always guides each client towards the decision that is truly best for them, never just the easiest sale. It is why every piece that leaves RKD is of the finest quality.
