QBD® is a jewellery manufacturer working at the final stage of the production chain. We handle both full manufacture — from a sketch, a CAD file or a physical sample — and final-stage processing on semi-finished pieces supplied by our clients.
What leaves our bench is a finished piece: set, polished, plated, inspected and packed. No further work needed on your side.
Our stones are lab-created, synthetic or simulated, and are labelled as such on every product page. We do not sell natural ruby, sapphire or diamond. Under FTC and EU guidance, lab-created material must be identified as lab-created — we would rather lose a sale than misrepresent a stone.
Untouched photographs from our production floor — no studio, no renders. This is what an ordinary working day looks like at QBD®.
