Thorough cleaning method: after the salt is dissolved, use a small bowl or teacup to hold warm water, and soak it for 24 hours every time 10g. Finally, dry it with a soft cotton-free flannel.

Cold water soaking method: use a small bowl or teacup, put salt into the bowl, soak the diamond in water for about 30 minutes, then gently brush the diamond in front, back, left and right with a small brush, then wave it in the water for a while, and then dry it with a paper towel after taking it out.

Quick cleaning method: buy a little salt, bury the diamond ring, purify and wash it. It takes 24 hours to bury each time, so there is a disadvantage that if the gemstone salt is treated manually, there will be artificially treated parts. Therefore, if it is an artificial gem, you can't use salt.
