Nuriel Diamond is a wholesale supplier of certified lab-grown diamonds, supplying jewellery manufacturers, retail stores, and independent designers across New Zealand and the Pacific Islands. Every stone is IGI or GCAL certified, laser-inscribed, and ethically produced.
We deal exclusively in lab-grown diamonds — never mined, never mixed. Every stone is independently graded by IGI or GCAL, laser-inscribed, and dispatched from our Auckland trade desk.
Every stone ships with an independent IGI or GCAL grading report. Laser-inscribed report number on the girdle, photo-matched, verifiable online.
We supply a single category — chemically, optically, physically identical to mined. 60–80% below mined price at the same grade.
Pricing fixed in New Zealand dollars; inventory held in Auckland; no currency surprises between quote and despatch.
Insured courier across NZ and the Pacific. Most orders confirmed by 4 pm despatch the next working day.

Same carbon, same lattice, same hardness. The only difference is where the crystallisation happened.
Nuriel Diamond is run by jewellers, for jewellers. We started the desk in 2026 because we couldn't get a straight answer or a fair NZD price out of the international wholesale market — too many middlemen, too much foreign-exchange risk, too many stones that arrived nothing like the report.
Today we hold inventory in Auckland, work directly with three growers in India and one in the United States, and supply trade buyers across New Zealand and the Pacific. Pricing in NZD. Stones inspected on arrival. Insured despatch on every parcel.
Quietly, but seriously.
Every stone is held in vaulted storage, fully insured, and dispatched on a chain of custody we can show you.
Held in a Class V trade vault on Queen Street. CCTV, dual-key access, biometric entry. Independently audited every quarter.
Underwritten by a Lloyd's of London syndicate. Every parcel is insured door-to-door at full retail replacement value.
Photo on receipt, photo on packing, photo on courier handover. Tracked, signed, end-to-end. Paper trail you can give your auditor.
