Shipping $50,000 worth of diamonds from China to New York. What could go wrong?
Everything. Unless you follow this guide.
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 Three Shipping Options

Cost: 1.5-2.5% of declared value
Insurance: Included up to $10M

Best For: Shipments over $100k
Option 2: FedEx Priority / DHL Express
Cost: $150-300 flat rate + 0.5-1% insurance
Insurance: Up to $50k (requires separate policy for higher values)
Transit Time: 2-4 days
Best For: Shipments $10k-100k
Option 3: Hand Carry

Insurance Red Flags
Read the fine print. Most policies exclude:
- Mysterious disappearance (no forced entry)
- Undeclared value (you must declare full value)
- War, terrorism, or civil unrest
- Improper packaging
Tout shipments over $20k use Brink's or Malca-Amit with full insurance. We never use regular couriers for high-value goods.
Customs Declaration Strategy
Declare the FULL value. Undervaluing to save on duties is illegal and voids your insurance.
