Gems
I have a selection of loose gems and jewels for sale.
See my shop for some of my current offers. I have other gems available, not shown on this website.
Please contact me if you have any ‘wants’.
Diamonds
I have been handling, identifying and grading diamonds in Hatton Garden since the late 1970s. On my website I offer a small number of diamonds for sale. I have had these diamonds for many years. If you are thinking of commissioning a designer to make you a bespoke jewel, I have a stock of loose diamonds for you to browse. I can help with the design and the making of your dream jewel.
All loose diamonds I offer are natural (I do not trade synthetic diamonds, so called laboratory grown diamonds), not treated in any way, and have grading reports from the GIA. I also have a small number of hand made diamond rings in platinum and gold, again accompanied by GIA reports, and also less expensive diamond rings.
