From mine to market

As a ‘First Hand of Trade’ diamond merchant we purchase our stones directly from South Africa’s diamond mines, before each diamond is cut and graded by hand.


Dealing direct from mine to market, First Diamonds are able to offer our clients exclusive access to a remarkable range of unique diamonds, each certified by the respected Gemological Institute of America. Alongside a range of dazzling investment stones, our selection of loose diamonds spans a variety of grades, cuts and sizes suitable for your choice of custom-made jewellery design.

Each of our diamonds and Tanzanite stones are graded and certified by internationally recognised gemmology laboratories to ensure authenticity and absolute peace of mind.
