Natural crystal is formed under natural conditions. It grows deep in the crust and usually experiences violent crustal movements such as volcanic and earthquakes. Natural crystals are mineral resources, very rare and precious, and are one of the gems.

Synthetic crystal:
Synthetic crystal is also called regenerative crystal is a single crystal, also known as synthetic crystal and voltage crystal. Regenerative crystal uses the water thermal crystallization method to "imitate the growth process of natural crystals", and place natural silicon ore and some chemicals in high-pressure kettles. After 1-3 months (for different crystals), it is gradually cultivated. It is exactly the same as natural crystal in terms of chemical composition, molecular structure, optical properties, mechanical, and electrical properties, while dual refraction and polarization, and the recycled crystals are purer and better than natural crystals and better color. After processing (cutting, grinding, throwing), the granules of various shapes are clear, dazzling, and wear -resistant, corrosion -resistant.
Melving crystal:
Many people in the market also call the melting crystal as the synthetic crystal. It is inaccurate. Generally, the crystal waste is melted out of the high temperature and high pressure, not the crystal, and the crystal characteristics of the crystal are not available. Mix the melting crystal with the synthetic crystal; but the melting crystal with high -quality silicon dioxide melting crystals can be made into practical products such as crystal cups, baking trays, tea sets, etc. The high -quality crystal of the East China Sea is made of melting.
K9 glass imitation crystal:
Some people also call the K9 glass as a synthetic crystal, which is even more wrong. Although the K9 glass is melted with silicon dioxide as the main raw material, it adds 24%of the lead during the melting process. In fact, the lead glass is actually the lead glass ; Why add lead? Generally, glass or green or green, it looks like crystal, but the whiteness of the glass after adding lead is very high, and it looks very like crystal, especially the 24%K9 glass is the most like crystal. appropriate.
