1, the density of jade is generally between 95 and 36 degrees, because different kinds of jade have different densities.

2. The density of jadeite: 30-36, generally 33 grams per cubic centimeter. Jade, also known as jadeite, jadeite and Burmese jade, is a kind of jade. The correct definition of jadeite is fibrous aggregate composed of pyroxene minerals, mainly jadeite minerals. But jade is not equal to jade.

3, different from the glass luster of agate, it looks brighter and appears shiny and rigid; Nephrite (also called Hetian jade) has a density of 95g/cm3 and a refractive index of 606-.632. Nephrite is generally translucent, showing greasy luster and so on.

Iron ore futures account status

What is the density of jadeite?

1, jadeite density 30-36. The correct definition of jadeite is fibrous aggregate composed of pyroxene minerals mainly composed of jadeite minerals, with a density of 30-36.

2. Relative density of jadeite: 30-36, generally 33 grams per cubic centimeter. Natural jadeite has a hard and dense structure, no bubbles, high density, and clear sound when knocking; Fake products have loose structure or bubbles, low density and hoarse knocking sound. Most jadeites that have been bleached and filled have slightly lower density and refractive index.

3. The density of jadeite is 33-34g/cm3. Jade, also known as jadeite, jadeite, jadeite and Burmese jade, is a kind of jade.

4. Generally speaking, the density of jadeite is 30 ~ 36, and the general appraisal certificate indicates 33, which is a large proportion and the refractive index is about 66. Hold the jade of the same size in your hand. If it is natural, it will obviously feel the pressure, if it is false, it will feel very light.

Statistically speaking, the density of jadeite is about 33 grams/cubic centimeter, so the general appraisal certificate will write 33. Because the composition of jadeite is not fixed, it is a collection of nano-pyroxene minerals mainly jadeite. Therefore, different types of jadeite usually have different densities.

6. Statistically speaking, the density of jadeite is about 33 grams/cubic centimeter, so the general appraisal certificate will write 33. Because the composition of jadeite is not fixed, it is a collection of nano-pyroxene minerals mainly jadeite. Therefore, different types of jadeite usually have different densities. Nephrite is also called hetian jade.

What is the density of Burmese jadeite?

Qinghai nephrite (Qinghai nephrite)-generally less than 0.5, Qinghai nephrite is nephrite produced in Kunlun Mountain, Qinghai. Nowadays, Qinghai nephrite with high quality has been recognized by many people in the market, and its gemological identification index is completely consistent with Hetian jade, so there is no obstacle in variety identification and classification.

Statistically speaking, the density of jadeite is about 33 grams/cubic centimeter, so the general appraisal certificate will write 33. Because the composition of jadeite is not fixed, it is a collection of nano-pyroxene minerals mainly jadeite. Therefore, different types of jadeite usually have different densities.

Burmese jadeite belongs to jadeite, its hardness reaches Mohs 7, and its density is 33 ~ 34 g/cm3. It is a grain fiber interwoven structure and has glass luster after polishing.

The density of jadeite: 30-36, generally 33 grams per cubic centimeter. Jade, also known as jadeite, jadeite and Burmese jade, is a kind of jade. The correct definition of jadeite is fibrous aggregate composed of pyroxene minerals, mainly jadeite minerals. Hetian jade (origin Xinjiang) Density: 95- 17.
