THE HOUSE
A DUBAI DIAMOND HOUSE WITH AN ANTWERP HEART.
Founded in 2016 as Rockstar Diam DMCC, we serve the world's leading diamond manufacturers, traders and private clients, procuring rough and polished diamonds through a long-standing network across the mining sector.
Rough. We source Kimberley Process certified rough directly from miners worldwide and hold tenders at our facilities in Johannesburg and Dubai: a committed buyer for producers, a consistent supply for manufacturers.
Polished. From our office in the Antwerp Diamond Exchange we polish and trade certified (GIA, HRD, IGI) and non-certified diamonds, graded honestly and offered with full documentation.
Jewellery. For more than a decade we have made fine jewellery for leading retailers under their own names. Today we also design our own pieces and take private commissions, from first sketch to finished jewel.
Discretion, accurate grading and relationships that last. Miners, manufacturers and private clients deal directly with the people who choose the stones.
OUR DIVISIONS
ROUGH DIAMONDS
We connect miners with the right buyers, and buyers with the right goods.
For miners: a committed, long-term buyer, and tenders at top-dollar premiums at our facilities in Johannesburg and Dubai.
For buyers: a consistent supply of natural, Kimberley Process certified rough from miners worldwide, and representation in all dealings with miners.
POLISHED DIAMONDS
Rough of 5 carats and above, hand-selected from our preferred sources and cut at our Antwerp facility. Every stone is GIA certified and conflict-free, and sold through Rockstar's own polished trading arm.
BESPOKE JEWELLERY
BESPOKE JEWELLERY
For over a decade we have created fine jewellery for leading retailers worldwide, sold under their names. Now we bring our own collection to discerning buyers: hand-picked rough, polished in Antwerp and set into the finished piece. Private commissions welcome.
EXCEPTIONAL STONES
CHOSEN IN THE ROUGH. REVEALED IN ANTWERP.
Rare coloured and white rough, selected stone by stone from the world's leading sources. Each is planned, cut and polished in Antwerp to reveal its finest possible light, then offered to the trade or set into a one-of-a-kind piece.
EVERY STONE BEGINS IN THE EARTH.
We buy directly at source and through the major tenders, with full chain-of-custody records. Every rough and polished diamond we trade is Kimberley Process certified and conflict-free, and each stone is checked under the loupe before it ever leaves our office.
EVERY STONE, UNDER THE LOUPE.
Colour, clarity and cut are assessed by our own graders in Antwerp before any stone is offered. Polished goods of 5 carats and above are GIA certified, and every parcel comes with honest, detailed notes from the people who chose it.
