We are generally available by appointment - Monday to Friday.

Loose Stones



T.O’D deals in a wide range of loose diamonds in a variety of diamond shapes, colours and sizes. Whether you are looking for a rare large diamond or a commercial pair of stones we have a large selection available from stock.


For decades we have been travelling the world in order to seek out the best international sources. Our extensive research and network enables us to purchase diamonds direct from source at a competitive price. We then pass our savings on to our customers, supplying diamonds at an excellent price.


As with our jewellery we stock only the finest quality diamonds, many of which are independently certificated by GIA or HRD. 


We also deal in antique and secondhand jewellery and hold inventory available on the margin scheme. Our old cut diamond stock is highly sought after and constantly changing. 


Coloured Stones


We also source and stock fine natural gemstones in a variety of shapes and sizes, including sapphires, rubies and emeralds – both heated or unheated – often certificated by Gubelin, SSEF and GIA.
