Ink is black jade
wrong!
Ink is a black or dark gray-green jade. Some people say that jadeite is the main component of jadeite, and other related minerals only account for a small proportion. In the high-quality ink green, omphacite has become the main component, so the ink can not be called "Jade". In fact, the content of mineral components is relative, and many scholars of jade research have extended the jade from the original narrow definition to the broad definition.
The omphacite jade is the ink
Correct! But not all right!
The most high-quality ink green and omphacite is the main component, and the texture is even and delicate. Many strict merchants believe that only omphacite accounts for more than 90%, which can be called ink green.
However, in fact, when the content of sodium chromite is high, the emerald appearance of the dark green appearance is also called ink green, but most of them are not good in texture, so they are also called "black jade". In addition, jadeite with jadeite as the main component tends to be very coarse in size, uneven in color, and the transmitted light is grayish black.
The reason why the ink is black is because there is a magazine.
Not all right!
The fine and even texture of the ink, due to the excess of chromium and iron, formed a black. The rough texture, which is rough and uneven under natural light, is caused by the inclusion of other mineral impurities such as hornblende.
