1. Ice jadeite is divided into four grades, as follows: A jadeite, natural jadeite, is a natural jadeite with natural color and fruit without chemical treatment. B-grade jadeite, bleached and glued jadeite, is a kind of jadeite that is glued by washing with strong acid. Soaking and cleaning with strong acid is helpful to improve the transparency and color of jadeite.

2. The second-grade ice jadeite belongs to jewelry grade, with bright colors and long planting water. Although it is not as good as the first-class product, its texture is relatively pure. Suitable for jewelry, jewelry stores are more common and easy to buy.

3. High-ice species: superior to general ice species jadeite, second only to ice species jadeite. Ice species: The transparency and water head of ice species are slightly lower than that of glass species. As the name implies, it is as transparent as ice and belongs to high-grade jadeite. Frozen glutinous rice: The texture is between transparent and opaque, just like cooked glutinous rice.

4. Three-grade ice jadeite is common, and it is also common in the market. This kind of jadeite is not as big as a gem, with rough texture, impure color, many surface cracks and uneven internal particle thickness, which is generally suitable for carving or jewelry.

5. Ice jadeite also looks pure and transparent. Unlike glass, it is only three minutes warm, but seven minutes cold. Although ice jadeite is not as precious as glass jadeite, in real life, real ice jadeite is hard to find except for commercial reasons.
