HCA fire color testing diamond is an American patent technology. Through this technology, we can find the top diamond category with a score of 1. Of course, this does not refer to a single diamond, but a kind of masonry. In the classification with a score of 1, we can find more high-quality diamonds. According to the international standard of target, 0.5- 1.5 is the standard value of fire color test and is also synonymous with quality. There are many methods for diamond identification, some of which also need professional instruments and equipment, but not all of them need such trouble.
