IGI Shanghai Certified, Fully Traceable
IGI's Shanghai lab is known for the strictest origin compliance auditing in the industry. Every stone ships with a certificate from Shanghai, and we select only diamonds with "No indication of post-growth treatment" on record. You get full traceability — no gray-market stones, no treatment hiding, no surprises.
3-Step Pre-Ship QC
Before anything leaves Henan, China, we run three checks: unedited video (white light fire + laser inscription on girdle + UV fluorescence), backed by an IGI Shanghai certificate — one of the strictest labs for origin compliance and post-growth treatment auditing.

How People Use This
Real scenarios from buyers who started with a single stone.
The Small Jeweler
"I run a small custom jewelry shop in Sydney. I was tired of chasing unreliable suppliers and inconsistent quality. Finding a trusted partner in Zhengzhou changed that. I ordered one 1ct stone to test the water — the QC video alone gave me more confidence than any listing I've seen online. Reordered 3 stones the next month. Now they're my go-to source."
The Couple
"We wanted a lab-grown diamond for the engagement ring but were nervous about buying online without seeing it first. We asked for a 1ct stone with full video — white light, UV, the whole thing. The stone arrived within a week, exactly as shown. No stress, no guesswork. Just a beautiful diamond."
