I bought a sapphire in lac, and there is no diamond in the ring arm. The quality is really good. To tell the truth, people who don't know how to do it really don't know what a gem is like, but the result of my own appraisal is the same as their appraisal certificate. I feel that the effect of wearing it is much better than that of photos. Upstairs, it's a bit unkind to say that the gem is flaky, and the proportion of the table I cut is still normal.
