Is it true that the opaque jade sheet can't be seen from the picture?

Not necessarily, some jadeites are transparent but not good, and opacity does not mean bad.

Emerald is polycrystalline, mostly translucent or even opaque. It is impossible to be as transparent as a single crystal gem such as jade, so that light can pass freely and appear crystal clear. Jade is translucent, but it is not good to be too transparent or opaque.

Common varieties include Laokeng jadeite, ice jadeite and water jadeite.

1. Emerald in ink painting: Black ice is gray-black to dark-black jadeite, and more than 98% is jadeite, which belongs to single mineral rock with compact and delicate structure. Black is formed when jadeite is formed under the surface, which is often formed by the infiltration of organic carbon. Black ice schist is mainly produced in Pagan Mine, Myanmar, and black ice raw materials can also be seen in auctions in Naypyidaw and Yangon, Myanmar. In the industry, because of its black texture, it looks like an ink landscape painting, and the old experts also call it "the ink painting of jadeite".

2. Cui Mo: At first glance, it is shiny black, which can easily be mistaken for jet in dushan jade or other black gems. It is dark and oily under natural light, translucent under transmitted light, and green in black, especially the thin Cui Mo, which has a gratifying color under transmitted light. Burmese people use the "lover's shadow" to describe the black jade, and China people named it "Cui Mo".

3. Purple jade: This is a kind of purple jade, the color is like violet flowers. The jewelry industry also calls violet "spring" or "spring". Emeralds in "spring" are divided into high, medium and low grades. Not only violets must be valuable, they must be top grade. Must be combined with quality indicators such as texture, transparency, and technology for comprehensive evaluation. The purple on jadeite is generally not deep. According to the different shades of purple, the jadeite industry divides the purple in jadeite into pink purple, eggplant purple and blue purple. Pink purple is usually fine in texture and good in transparency, followed by eggplant purple and blue purple again.

4. Maya Jade: Although fine in texture, it is opaque and has a porcelain-like luster on the surface.

5, green jade on a white background: the characteristics of green on a white background are as white as snow, and green on a white background is very bright. This variety of jadeite is easy to identify: there are green spots on the white background, and the transparency is poor, opaque or slightly transparent; Jade pieces have fiber and fine grain mosaic structure, but the fine grain structure is the main structure; Observed under a microscope (it must be magnified 30 ~ 40 times), its surface is often perforated or uneven.

Most of this variety is mid-range jadeite, and a few are blue and white, with bright and bright color, which is in harmony with the background and can reach middle and high grade.
