The crystal we are talking about is mostly this colorless and transparent crystal, but its English name is not Colorless Quartz but RockCrystal. The word Crystal comes from the Greek word krustallos, which means ice, because the ancient Greeks thought it was an eternal ice crystal given by the gods, so it was named after it; in gemology, natural crystals are added with Rock to match artificial Lead crystal glass is distinguished, because synthetic lead glass also has crystal in the English name. In order to avoid name confusion, the natural colorless transparent crystal is called Rock Crystal.
There are too many magical powers endowed by crystals. It is said that the ancient Egyptians placed the dead in front of a mirror and placed crystals on their foreheads to purify the soul. People with superpowers said that crystals have the power to absorb bad human emotions. Covering the forehead with crystals can absorb negative emotions such as fear and uneasiness in the human mind, and make people feel more cheerful.
The name Citrine is derived from its lemon yellow hue, derived from the English root (citrus) of lemon and citrus. The color of citrine is the result of the increase in temperature when the crystal is formed. Natural citrine is rare and usually lemon yellow. Most of the thick orange citrine on the market is heated, which is widely used in the jewelry industry. The accepted treatment, but the pleochroism of heat-treated citrine will be worse, so the pleochroism of different tones cannot be seen from different directions of the gem.
À présent, most of the citrines sold on the market are the result of amethyst or smoky quartz heat treatment. Amethyst will gradually turn yellow when heated to 470℃, and will turn into thick yellow to deep orange when the temperature rises to 550℃ to 560℃ Yellow; while the smoky quartz has a lower discoloration temperature, and the smoky quartz will turn into yellow crystal at 300°C to 400°C.
