For jewelry retailers and designers entering the lab-grown market, the B2B landscape can be confusing. From "As-Grown" vs. "Post-Growth" to navigating customs from China, we've compiled the most critical questions our 500+ wholesale clients ask.
1. Sourcing & Quality Questions
Q: What is the difference between "As-Grown" and "Post-Growth Treated"?
A: This is crucial for high-end B2B buying. "As-Grown" (typically HPHT) means the diamond came out of the press with perfect color. "Post-Growth" (often CVD) implies the stone was originally brown or gray and was treated (HPHT annealed) to improve color. Kunlun Growth prioritizes As-Grown HPHT for D-E color goods to prevent any risk of color reversion or milkiness.
Kunlun Growth Quality Promise
Certificates don't tell the whole story. We reject ~35% of diamonds that pass standard IGI inspections but fail our internal checks.
- No Brown/Green Tint: Every stone is compared against our Master Set.
- No BGM (Milkiness): We filter out hazy crystal structures.
- Eye-Clean Guarantee: Real-world visual inspection, not just 10x loupe.
Q: Do your wholesale diamonds pass standard diamond testers?
A: Yes. All lab-grown diamonds are chemically identical to mined diamonds and will test as diamond on thermal testers. However, they may be identified as "Synthetic" on advanced UV/SW testers, which is industry standard and necessary for transparency.
2. Business & Logistics (B2B)
Q: Is there a Minimum Order Quantity (MOQ)?
A: Unlike traditional factories requiring $50k+ opening orders, Kunlun Growth has NO MOQ. We support independent designers who may need just one specific 2.5ct Oval for a custom engagement ring client.
Q: How do you handle shipping from China to the US/Europe?
A: We provide door-to-door service using FedEx International Priority or Malca-Amit.
- Time: 3-5 business days.
- Customs: We handle the commercial invoice and HS Codes correctly to ensure smooth clearance.
3. Pricing & Market
Q: Why import directly instead of buying from US wholesalers?
A: US wholesalers typically markup Chinese goods by 30-50%. By sourcing directly through our supply chain partner model, you access factory-gate pricing. For a 3ct CVD stone, this can mean saving $800-$1,200 per stone, which goes directly to your bottom line.
