Lab-grown CVD Type IIa diamonds — IGI-certified, 1 to 16 carat, best qualities only — at $250–500 a carat, up to 90% under mined. And the backlit onyx feature walls of five-star lobbies, from $600/sqm installed. Direct. Wholesale. One address: 0@black.industries.
Both are real diamonds. One is grown by brilliant minds; the other is dug up to keep you paying. Be smart — choose the better product.




Representative high-jewellery imagery — every stone supplied is lab-grown CVD, Type IIa, and IGI-certified to its stated carat, cut, colour and clarity.
I prefer perfect diamonds. The microscopic imperfections in mined stones put me off — and only the finest laboratories on earth can grow a diamond without them. Nature can't. A CVD Type IIa stone is the purest form of carbon there is.
I also can't stand the artificial rarity. Mined diamonds run on manufactured scarcity — by industry estimates the great majority never even sell, sitting in warehouses to prop the price up. And the money funds the private jets of people who wouldn't think twice about you.
Lab diamonds look prettier, carry fewer imperfections, are inherently conflict-free — and they reward hardworking people and brilliant minds. That's the better product.
We certify with IGI only. In our experience GIA adds roughly 70% to the cost for paperwork that tells you what IGI already does — so we skip it and pass the saving to you.

Natural onyx, cut thin and lit from behind, turns translucent — the veins catch fire from within. I found the single cheapest direct supplier of it on earth. And no — it isn't where you'd think.




Imagery shows natural onyx and translucent stone lit to the brand palette — exact vein pattern and translucency vary specimen to specimen and are confirmed against physical slabs before fabrication.
