Artificial crystals are non-natural ways but are formed by artificial growth of silicon dioxide single crystals. The artificial crystal growth method has a hydrothermal method. It can grow more purely than natural crystals, and it is less flawless. Artificial crystals have exactly the same physicochemical properties as natural crystals.
At first glance, the selection of materials: crystal materials with excellent materials should not see star-shaped, cloud-like and flocculent gas-liquid inclusions. The texture is pure, smooth, and crystal-clear. If you find cracks and spots with different shades, it is a defective product.
Second, look at the work: the processing of crystal products is divided into two types, namely the grinder and the engraver. Such as crystal necklaces, bracelets, earrings, etc. are abrasive products; Guanyin image, inner painting snuff bottle, etc. are engravings. A well-made crystal product should be refined, not only can fully reveal the external beauty (styling, style, symmetry, etc.) of the crystal product, but also can maximize its inner beauty (smooth, clever color).
Three look polishing: the quality of polishing directly affects the value of crystal products. The crystal must be honed by diamond sand during the processing, and the rough production will cause traces of friction on the crystal surface. Good crystal products have better natural transparency and luster, and they are said to be "fire heads".
Four look at the hole: For the wearing of crystal products (such as necklaces, bracelets, beads), it depends on whether the hole is straight, the thickness of the hole is symmetrical, with or without small cracks. The wall of the hole must be clear and transparent, without "white marks".
Five colors: Even in the same kind of crystal, the texture and color of different parts of it are different. It belongs to a single color, and the chromaticity is uniform. If there is a shade on the same crystal, the color tone is required to be beautiful.
Six look at coordination: When buying crystal jewelry, you should try to wear it to see its size, tightness and length. If it is inlaid with ornaments, see if it is firm, Zhou Zheng and coordination. Also pay attention to whether the style and color of crystal jewelry are coordinated with your body, skin color, face and clothing.
