There are some stones whose composition is also Si02, but they are not crystals, but cryptocrystalline crystals.
To figure out the concept of “cryptocrystalline” is not a simple matter. It requires some knowledge of mineralogy and crystallography. This book will not explain it in detail. But you need to be clear that, although the chemical composition of cryptocrystalline crystal is also Si02, its structure is very different from that of crystal, so it is not crystal but jade in the strict sense.
Cryptocrystalline crystal is called “quartz jade” in the professional field, including tiger’s eye, eagle’s eye, agate, chalcedony, yellow dragon jade, osv. The dzi we know well is actually a kind of agate, belonging to the category of quartz jade.
The price of most quartz jade is relatively low, but the newly discovered huanglong jade in recent years can be described as the upstart of a large family of quartz jade, and the market price of high-grade huanglong jade is close to high-grade jade. Imidlertid, due to the many controversies surrounding Huanglongyu in the industry, the future market prospects are still unpredictable.
Friends who have taken photos in the studio group may have the “crystal photo frame” presented by the studio, right? Do you really believe that it is a crystal? Although I am not sure of the exact materials of those frames, I can tell you responsibly that they are all imitation crystals.
Imitation crystal, as the reputation is not real crystal, it is the collective name of crystal imitation. Any transparent thing imaginable that can be used to imitate crystal can be used to imitate crystal, which includes various other transparent artificial materials. It can be imitated, but as to whether imitate looks like or not, that is another matter. Imidlertid, we will always naturally associate “fake” with counterfeit and inferior products, and no one will be so stupid as to sell diamonds as crystals. Derfor, an important fact is that the price of imitation crystal material must be cheaper than natural crystal. Så, the most ideal crystal-like material is undoubtedly glass.
If the merchant tells you that he sells “imitation crystal”, it is equivalent to telling you two facts clearly: first, it is not crystal; second, it is most likely glass or plexiglass.
