If you’re looking for a lab grown diamond jewelry supplier China, the smartest move is to head to the wholesale market stalls in Guangzhou or Shenzhen. Here, you can inspect diamond clarity, cut, and metal finish in person, and grab spot goods ready for shipment. Avoid middlemen; go straight to the source.
Why China Dominates Lab Grown Diamond Jewelry Supply
China produces over 50% of the world’s lab grown diamonds. Manufacturers in Panyu, Guangdong, have mastered HPHT and CVD processes. The result? High-quality stones at 60-80% lower cost than natural diamonds. Plus, Chinese jewelers are fast in customizing designs and producing consistent quality in bulk.
Wholesale Market Stalls: Your Best Bet for Spot Goods
Stalls in markets like Soudangkou (a major gem trade hub) offer immediate inspection of finished pieces. You can check facet sharpness under a loupe, test metal weight by hand, and ensure prong settings are secure. Never rely on photos alone. When you visit, ask for stock list – they always have ready inventory for export.
3 Tips to Evaluate Quality at the Stall
- Diamond color & clarity: Ask for IGI/HRD certificate on site. Look for D-F color, VS clarity minimum.
- Metal finish: Run your finger over the edges – smooth means good polishing. Check stamps (e.g., 925, 750) for gold purity.
- Setting sturdiness: Gently shake the pendant – no movement means tight claws. For rings, check shank thickness for daily wear.
