Fashion collectors like to collect the natural crystal, but often see Zou Leyan in the market, face a large number of synthetic crystal. How to distinguish between natural crystals and synthetic crystals? The following are three different difference between the two:
First, the amethyst of the chromophore and color film. Synthetic Amethyst, often directed better dark purple film, it is tempting to associate the characteristics of natural amethyst irregular flakes chromophores. The biggest difference is the synthetic amethyst in deep purple chromophore was almost parallel to the sheet arrangement, size and shape is not very different, and the obvious boundaries; chromophores of natural amethyst irregular shape, hue, depth of change, and boundary gradient. If synthetic amethyst purple piece compared to a floating "purple cloth is natural amethyst purple group can be regarded as a floating" Zi Yan group.
Two hexagonal ribbon parallel ribbon. Other natural amethyst is characterized by: the same as sapphire hexagonal ribbon. Synthesis in the green crystal ribbon often was parallel to the ribbon along the crystal parallel to the nuclear wall layer by layer development. The emergence of a synthetic green crystal necklace, yellow and green and white, much like the natural crystal ribbon, coupled with internal brown translucent solid impurities can easily be mistaken for is a natural green crystal, but the synthetic crystal formation of the ribbon is nuclear wall parallel distribution along the crystal necklace made from a whole string of crystal ribbon change, every one of the ribbon width mere mention of the same, giving a too much "in step" and not natural feeling.
Inclusions and the difference between cotton. Often the inclusions in the natural crystal and cotton, synthetic crystal crystal clear, individual bubbles or solid impurities. Recently some synthetic crystals are often some of the triangle of long tubular pores, these pores in the green or red powder. The characteristics of this long tube is arranged in parallel in one direction, the cross section for the triangle, which are often uneven, green or red powder along the wall distribution, the middle is often empty, long tube ends are sharp change of trend. The real natural crystal is a crystal containing actinolite, rutile and other minerals, these minerals have their own crystal. They are wrapped in the crystal, non-directional random arrangement, thickness and length vary and is often accompanied by a natural crystal inclusions, and cotton.
