Last month, a client in Dubai nearly lost $45,000. He was buying a 5ct D VVS1 HPHT stone from a "trusted" supplier in Guangzhou. The IGI certificate looked perfect. The price was "too good to pass up."
The certificate was fake.
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.
The Problem Is Growing
As lab-grown diamond prices drop, the incentive to commit fraud increases. Fake certificates are now sophisticated enough to fool even experienced buyers.
Here's how to protect yourself:
Red Flag #1: The Report Number Doesn't Verify Online
IGI has an online verification system at igi.org/verify-your-report. Enter the report number. If it doesn't pull up, it's fake.
But here's the trick: Some scammers use REAL report numbers from different stones. So even if the number verifies, you need to check that the 4Cs match exactly.
Red Flag #2: The Laser Inscription Is Missing or Wrong
सभी IGI-certified lab-grown diamonds should have the report number laser-inscribed on the girdle. If the stone has no inscription, or the inscription doesn't match the certificate, walk away.
Red Flag #3: The Price Is "Too Good"
If a 3ct D VVS1 is being offered at 20% below market, ask yourself: Why?
Legitimate suppliers operate on thin margins. Deep discounts are a red flag.
Red Flag #4: The Seller Rushes You
"This stone is reserved for another client, but I can hold it for you if you wire 50% deposit today."
Pressure tactics are a classic scam indicator. Legitimate suppliers will give you time to verify.
Red Flag #5: No Physical Verification सभीowed
If the seller refuses to let you inspect the stone in person (or via a trusted third party), that's a major red flag.
Every stone we ship includes:
1. Original IGI certificate (we verify before purchase)
2. Laser inscription matching report number
3. Video under different lighting conditions
4. Option for third-party inspection in Shenzhen before shipping
What to Do If You Suspect Fraud
If you've already paid and suspect the certificate is fake:
- संपर्क करें IGI directly with the report number
- File a police report (yes, even for international transactions)
- संपर्क करें your bank to attempt a wire recall (time-sensitive)
- Report the supplier to industry groups (e.g., JVC, CIBJO)
Prevention is better than recovery. Work with suppliers who have verifiable track records and transparent processes.
