The advantage of buying direct
Most jewellers buy from wholesalers who buy from dealers who buy from cutters — every hand takes a cut. We source diamonds first-hand from mines in and around South Africa, so you pay for the stone, not the supply chain.
Unbeatable Value
Direct sourcing means no middlemen, no markups. You get a superior stone at a price that would be impossible on the high street.
See It Before It's Made
We create a detailed CAD design for your approval before production begins. No surprises — just exactly what you envisioned.
Expert Selection
We hand-select 2–4 diamond options based on your brief. Every stone is chosen for cut quality and brilliance — not just carat weight.
Made In-House, A to Z
From raw stone to finished piece — everything is handled by our team. No outsourcing, no compromise on quality.
From consultation to creation
No diamond experience needed. We guide you through every decision — in person at Hatton Garden or online.
Share what you're looking for, your preferred style, and your budget. We'll take it from there — no pressure, just honest advice.
We present 2–4 hand-selected diamond options tailored to your brief. Every stone is certified and chosen for exceptional cut and brilliance.
Our designers create a CAD rendering of your piece. You approve every detail before we begin production — typically 2–3 weeks.
We send you a video of the finished piece. Pay the balance and collect from Hatton Garden — or we ship securely to your door.
