Sarı, brown, and orange can be turned into pink or red by heating. This color is stable and will not change; yellow and orange can deepen the color or remove impurities by radiation treatment.

Blue topaz is sky blue, often with a little gray or green hue, with obvious pleochroism, blue or colorless. Contains more. Blue topaz is more popular in the international market, looks like aquamarine, but the price is lower.

Colorless topaz is abundant in nature and has large crystals. Because of its high refractive index, it is polished into a faceted gemstone, and it is not so attractive. Öyleyse, it is often subjected to radiation treatment to turn colorless topaz into blue topaz. The small particles of colorless topaz are very close to diamonds, and can be used as a group setting or matching stone instead of broken diamonds. It can be described as cheap and good. High-quality topaz requires not only beautiful color, but also clean interior, regular cut, and bright glass luster.

Gemstones similar to topaz include quartz, turmalin, akuamarin, phosphorite, and glass products, which can be distinguished by density and refractive index. Örneğin, tourmaline has obvious edge and ghost, and its dichroism is much stronger than that of topaz; the relative density of aquamarine is low, yani, for gems of the same size, aquamarine is relatively lighter.

Brazil is rich in topaz. The world’s high-quality Yinchi stone gemstones come from Brazil, mainly orange and orange-brown gem-grade topaz. Other places of origin include Sri Lanka, Russia, the United States, Mexico, Myanmar, and some countries in Africa.
