Type of jade

White, yellow, green, transparent, translucent, opaque, thousands of emeralds on the market. There are also thousands of agate species in the industry. What kinds of jadeite are there? Old species, new species What is it? In this issue, let’s explore the “species” of jadeite.

The "species" mentioned in the jade industry actually contains two aspects. One refers to the size of the mineral crystal particles inside the jadeite, and the other refers to the density, hardness and the degree of crystallinity of the mineral crystals. According to the size of mineral crystal particles, jadeite can be divided into glass species, ice species, alfalfa species, hibiscus species, horse teeth species and bean varieties. According to the latter, it is divided into old (pit) species, new (pit) species and new and old species.

The transparency of the glass species is good and the hardness is also the highest. The old pit glass species can be said to be synonymous with the most high-grade jade. The value of the colorful Yunnan town store treasure "outstanding style" is nearly 300 million, which is composed of 9 old pit glass species jadeite. of. Ice is second only to glass, three points are warm, seven points are cold, and it is also a high-grade jade. Next is the species, hibiscus species. When talking about jadeite species, people often hear "water heads". The water head refers to the transparency of jadeite, the head is long and the transparency is good. Pay attention to the intensity of light and the influence of jade thickness on the water head.

Although Jade's "species" and "water" are two different concepts, there is a certain relationship between the two. In general, the jadeite is fine, the jade meat is fine, and the water head is generally good. If the jadeite is not good, the water head will be worse due to the coarse internal mineral crystal particles. However, although some jadeites are not well grown, the crystal grains are coarse, but the crystals are very tightly bonded to the crystals, and the water heads are also very good. Therefore, it is necessary to dialectically treat the relationship between the two. Trainee reporter Li Yuan
