If you count the airfare and other expenses, it will not be cheaper than domestic ones. If you happen to know diamonds when passing through South Korea and compare the prices in China, you can visit South Korea.

The above information is relatively large. It doesn't matter where you bought it for your wedding. If you invest in collection, you can compare it more. Foreign countries are not necessarily cheaper than domestic ones!

When comparing diamonds, it is necessary to compare them at the same level, such as domestic GIA bare diamond D color, IF clarity, 3ex cut, 1ct, and non-fluorescent first-hand diamonds compared with foreign counterparts, which is more objective.

I hope it helps you!
