Graham Tom – Diamond Experts

Welcome to my site. I am a fourth generation diamond expert, gemmologist, registered valuer, expert witness and bespoke jeweller based in London with over 30 years professional experience and commitment to excellence of service.

If you are looking to purchase a diamond or gemstone for either bridal, anniversary, lifestyle jewellery or as a collector of significant gemstones, I will broker, advise and help you make the right choice and offer you peace of mind with ethically sourced diamonds accompanied with GIA reports. I will also ensure the brilliance and impact of your choice of gemstone is complimented by our customised lifestyle service delivering innovative design and bespoke jewellery created by talented goldsmiths in the UK.

Other value added consultancy services include valuations of jewellery for differing purposes, expert witness court reports, teaching diamond and gemstone short courses, masterclasses to the trade and enthusiast and route to market selling pre-owned jewellery.

We look forward to meeting you.
