Thousands of pure gold and pure gold are very soft and not suitable for setting gems. The setting is unstable and easy to fall off. Therefore, it is generally not necessary to use pure gold and pure gold to set gems.

Gemstones are mainly 18K gold, that is, gold with a purity of 75%, and platinum with a purity of 95% and PT900%. Platinum with a purity of 99% is also soft and not suitable for inlaying.

If the landlord bought it in a regular store and gave it to you as thousands of gold, it should be thousands of gold and can be trusted; It's hard to say if it's a store without credibility:)

If they invoice, it means pure gold, thousands of gold, and the landlord can go to the appraisal agency for appraisal. If it is fake, pure gold and thousands of gold are exchanged for K gold, and the landlord can claim compensation.
