![]() Uncut Onyx As the name implies, natural minerals are not treated in any way to alter color, hardness, etc. Natural gemstones are usually cut and polished to best display their natural beauty. Imitation refers to materials that are not gemstones at all. Materials such as plastic and glass are colored to mimic a real stone. Synthetic materials are man-made minerals created to mimic natural gemstones. Some are nearly identical to the gemstone to be duplicated, some are not. Treated gemstones are natural minerals that are altered to enhance the color, hardness or other quality of the final product. Naturally occuring gem quality black onyx is very rare. All material purchased should be considered to be color treated. Carbon is infused into clear onyx to make it black. This treatment is permanent. Since the stone is chemically exactly like natural black onyx, no test can determine that it has been color treated. |
