Crystal, a rare mineral, and a kind of precious stone, timely crystal belongs to the timely family in mineralogy. Its main chemical composition is silicon dioxide, and its chemical formula is SiO2. When pure, colorless and transparent crystals are formed. When it contains trace elements such as aluminum and iron, it appears purple, * *, brown and so on. After irradiation, trace elements form different types of color centers and produce different colors, such as purple, * *, brown, pink and so on. Inclusion crystals contain associated inclusion minerals, such as hair crystal, green ghost, red rabbit hair, etc. Inclusions include rutile, tourmaline, actinolite, mica and chlorite.

Evaluation criteria:

The evaluation standard of crystal is different from that of high-end gemstones. Most high-end gemstones put color first when evaluating. For crystals, color and clarity (called crystals in the crystal industry) are almost equally important factors:

Color: For any gem, color is very important, and crystal is no exception. If the crystal is colored, such as pink crystal, topaz, amethyst, etc. The highest standard of color evaluation is bright and moving, and there are no other shades such as gray, black and brown. Such as pink crystal, the color is better with pink; Amethyst, bright purple in color, pure but not black; Topaz, the required color does not contain green and lemon tones, and golden orange is preferred. For hair crystal, the color of crystal is also very important. Golden hair crystal hair, crystal completely colorless (white crystal) slightly brown, the visual experience of the naked eye is also different, so the price of the former will be higher than the latter.

Clarity: the clarity requirements of crystals and high-grade gemstones are very different. High-grade gems are scarce, so people generally don't ask too much for the purity of high-grade gems. However, the output of crystal is really amazing, so people usually require the higher the purity of crystal, the better, and try to avoid crystals with obvious inclusions.

Impurities: If there are legendary figures in the impurities in the crystal, such as Buddha, constellation, zodiac, etc., its value may be higher than that of the crystal with the same color and clarity.

The state has not provided a specific grading standard for crystals. There are many kinds of crystals, and each variety has its own different standards.
