Visit our eBay boutique London Diamond Exchange
We are a London-based jeweller, curated by hand and sold through our five-star eBay boutique — every piece tested, checked and packed with care before it travels to you.
Every LDX piece is made with a laboratory-grown stone, and we tell you plainly which kind you are buying — on the listing, in the paperwork and here.
Grown in a laboratory rather than mined from the earth, laboratory-grown diamonds are chemically, physically and optically identical to natural diamonds. Every fine diamond we sell is graded and certified by the International Gemological Institute (IGI), with its independent report to prove it.
Our SiC verified stones are described on our eBay listings as “Lab-grown (SiC Verified): Diamond Selector Approved”. Each one passes the Diamond Selector test and is accompanied by our LDX Card of Authenticity.
Whether it is an IGI certificate or our LDX Card of Authenticity, every order arrives with the proof of what your stone is — no ambiguity, no guesswork. Fine pieces are hallmarked, and every purchase is described accurately.
Can’t find the piece you are imagining? We fabricate fully custom jewellery — rings, necklaces, bracelets and earrings — in silver, gold and platinum.
The proof is in the pieces
