Fundamental Knowledge and Standard of Crystal

Some natural crystal beads will contain a number of cracks more or less, thus, what is the main reason? Some will blame this on the quality of crystal. They think it is very common for cracks appear after wearing for a long time. In general, all these issues are not entirely wrong but not absolutely right as well. In fact, all natural crystals will involve a certain amount of impurity or cracks, and there is no exception of the very pure ones. If you can come across one with pure crystalloid, large size, no crack and impurity, so congratulations, you will be a real wealthy then! But it may come by something with luck, but not by searching for it!

Furthermore, about how to distinguish and identify different grade crystals, it is not differing distinctly in grades like Mohs hardness, the standard for judging the quality is only jointly agreed by the early operators of the market. Thus, for picking out fine ones from?wholesale beads and charms suppliers,you can simply refer to the following rules that are common used:

1. AA Grade (generally called the 3A grade in market): pure crystalloid with nearly no impurity, in addition, no scar on the surface causing by Later Processing.

2. A Grade (generally called the 2A grade in market): not perfect as same as the 3A ones, it may include a few flaw like some unavoidable natural inclusions or some tiny scar by mankind that may difficult to uncover.

3. A Grade. The crystals may contain some visible flaws or human impact scars on surface.

4. AB Grade. The flaws may appear larger in size than the A Grade ones.

5. B Grade. The impurities and inclusions may occupy nearly half of the crystals, and the ice crack can sometimes feel by fingers.

6. C Grade. This grade is the lowest quality one. The amount of flaws scars on surface may be more obvious.
