Both Mo Cui and Mo Yu are very dark, and some even say that "Mu Yu is Mo Cui." Learn with the Cui factory, which black jade can't be called ink jade or ink jade:
Black hetian jade
Dark green nephrite, also known as jade, soft jade texture is lighter, luster is grease luster, natural light surface is dark green, not pure black.
Black rock
The black rock looks more like glass and is a black or dark brown acid vitreous volcanic rock with almost the same composition as granite. Except for a small amount of phenocrysts and crystallites, it is almost entirely composed of vitreous.
Black agate
Black agate is dyed and has the same composition as red or striped agate, which is silica. The polished agate is much darker than the ink.
Black jade
Also known as serpentine jade, light weight, fine texture, can not see the grainy feeling, dark green to black green, relatively transparent, fine texture, and similar to the ink, is the emergence of more imitation ink on the market. The handcuffs are lighter, the hardness is lower than that of the ink, and the surface is lustrous and not as good as the ink. Fine-point, clump-like black magnetite metal mineral inclusions often appear inside, and plaques that reflect metallic luster can be seen on the reflective surface.
Yong Chu
"Guatemala, Yong Chu material" you must be careful!
There is a kind of chrome from Guatemala. The main ingredient is omphacite, but the secondary ingredients are different from those of Burma. Since the test certificate only issues an identification certificate according to the composition, the certificate that has not been optimized will be marked with: A cargo jade, omphacite as the main component. And this kind of ink is far from the price of Myanmar's ink. However, experienced merchants and jade collectors generally do not recognize the origin of the ink. When you buy, you have to think carefully!
