Diamond Buy-back & Exchange Policy - Thảo Linh Jewelry
Thảo Linh's buy-back and exchange policy is transparent and public: every figure is based on the original invoice price, only a fixed percentage is deducted, and it is printed clearly on the receipt — no case-by-case haggling, no pushing the price down when you need to sell.
Faulty or wrong items (online orders)
Items with a manufacturing fault, or that are not the item you ordered, are exchanged for the correct item if you tell us within 48 hours of receiving the parcel, with a video recorded while unboxing. Thảo Linh pays the shipping; faults are inspected and confirmed by Thảo Linh.
Items without a fault cannot be returned or exchanged, and Thảo Linh does not give refunds in any case. A wrong ring size provided by the customer is not a fault; we can adjust the size through our resizing service. If you want to sell a piece back or change to another piece, the buy-back and exchange policy below applies.

“Trade-up” means exchanging for a piece of higher value. Conditions: you still have the invoice and grading report, and the item is in its original condition.
Example: a natural round diamond ring invoiced at 100 million VND → sold back for 85 million VND; if traded up to a higher-value piece, the stone is credited at 90 million VND.
