Green ghost crystal (green crystal), a kind of amethyst. The key organic chemical component is silicon dioxide. The chemical equation is silicon dioxide. Because it contains magnesium and iron chemicals, it is emerald green, and its output is scarce, which means the capital accumulated due to hard work.
The red ghost is called emerald phantom amethyst, and the emerald mineral in the red ghost crystal is emerald volcanic mud, which often appears in pure natural conditions such as fog and aquatic plants. At present, it is common to synthesize green crystals on the market. In amethyst, there are chlorite, five-element wood and ladder array in summer for purification.
First of all, a good green ghost crystal has high transparency, and the lower the defects such as cracked cotton, the better. This is not only applicable to the selection of green ghost crystal, but also should be paid attention to when selecting other types of amethyst.
Secondly, to find out how to choose the green ghost crystal, we must identify the ghost quality of the green ghost crystal. According to the appearance, the ghost body of green ghost crystal can be divided into three types: Egyptian pyramid (Thousand-layer Mountain), Jubao plate, mixed type and dispersed type, among which the green ghost crystal with Egyptian pyramid shape has the greatest use value, followed by Jubao plate, and the scattered type of all over the sky is the worst.
Among the ghost bodies with a thousand layers of mountains, the shape of the ghost is very textured layer by layer, which is even more precious if it can become an Egyptian pyramid or a mountain. The inclusions in the cornucopia green ghost crystal are loose, such as slag or paste, and the total amount is preferably about half of amethyst. Too much or too little is harmful to artistic beauty; For mixed and dispersed amethyst, the more inclusions in crystal, the better.
Finally, it depends on the ghost hue of the green ghost crystal. To put it bluntly, green ghost crystal is green and environmentally friendly, among which emerald green and dark green are the best. Other types of ghost crystals in amethyst are milky white, bright red, dark gray and silvery white. Some green ghost crystals contain not only red ghosts, but also ghosts of other colors, such as red ghosts and Honky, which are of low use value. These Red Ghosts and Honky are crystal residues for Green Ghosts, which will make the price of Red Ghosts plummet.
