The density of jade depends on the kind of jade. Different kinds of jade have different densities, so do different kinds of jade. The density of common jade species is as follows: the density of jade is 3.30 to 3.36, generally 3.33 grams per cubic centimeter. The density of Hetian jade (produced in Xinjiang) is 2.95 ~ 3. 17. Turquoise density: 2.6 to 2.73. Qinghai Cui: 3.6 1+0. 12 to 3.61+0.04; Emerald: 2.57+0.23 to 2.57+0.13; Dongling jade: 2.64 to 2.71; Dushan jade: 2.7 to 3.09.

According to the statistics of jade detection in Longcheng, the jade density of Hetian jade including Xinjiang Hetian jade, Russian jade and Qinghai jade is between 2.9-3. 1. The density of common counterfeits such as afghanistan jade, hard water stone, Gobi stone, marble, xiuyan jade and chemical zirconium is between 2.6 and 2.8, and the counterfeits pressed by jade powder are even lower than 2.5. The density of Hetian jade is between 2.66 and 2.976. Different hetian jade has different differences: hetian jade is 2.922; Blue and white jade is 2.976; Moyu 2.66. Generally speaking, white jade is lighter than sapphire or sapphire, and jet is lighter because it contains lighter graphite scales. Specific gravity is of great significance in jade identification. It is worth noting that the higher the proportion, the better its market value. For example, Hetian jade has a slightly lower proportion than serpentine nephrite. In addition, the ratio of Manas jasper in Xinjiang is 3.006; The ratio of nephrite in Canada is between 2.5-3.0 1, with an average of 2.99; Nephrite in New Zealand ranges from 2.95 to 3.02, usually 2.9.

Jade is a multi-product aggregate of stone that reaches the jade level under geological action. It is mainly composed of jadeite or jadeite, sodium (sodalite) and sodalite (omphacite), and may contain amphibole, feldspar, chromite and limonite. Usually jade refers to nephrite, which is one of the most common jewels. China is the first country in the world to exploit and utilize jade. In a wide range of countries, the most famous jade is Hetian jade in Xinjiang, as well as dushan jade in Henan, xiuyan jade in Liaoning and lantian jade in Shaanxi. Together, they are called the four famous jade in China. Emerald is rich in trace elements such as zinc, iron, copper, manganese, magnesium, cobalt, selenium, chromium, titanium, lithium, calcium and potassium. The embellishment of jade can eliminate impetuous heart, and the color of jade can steal boring heart, so a gentleman loves jade and hopes to find natural aura on jade.
