Grape stone is a kind of gemstone. The color of the stone is green. It is similar to the color of the grape. Its shape is similar to that of the grape. It is crystal clear and is therefore called grape stone. So how do you identify grape stones? The following small series will be briefly explained for everyone.
Grapevine identification method
The fine grape stone will have the normal "fluorescence" of the similar glass type jadeite, which is very pretty. The color of the grape stone is dark green-green gray green-green green-yellow green yellow green-yellow colorless, etc., occasionally gray. However, in general, the green color-based grape stone is colored with yellow or gray color, and the yellow color-based grape stone is generally brighter than the color but not with the gray color. In terms of analysis, the color is not enough. pure.
The good grape stone is generally a disintegrated body, dark green. But normally, this kind of data is uncomplicated because of the single crystal body, because there are few single crystal facets, which is rare. Most of the wild grape stones on the market are colorless wild grape stones produced in Hebei. And most of them are disintegrated, and after processing, they are similar to colorless jade. Because some merchants will use the fine wild grape stone as a substitute for excellent jadeite, please pay attention to the difference.
The grape stone is clean and the color is pleasing to the eye, and the particles are large and round and dry. In the past one or two years, Wild Grape Stone has been favored by many visionaries in China. In particular, it is also making a horn in Taiwan. The second reason is that in many natural gemstones with similar jade appearance, the wild grape stone has the most environment. Have a disadvantage. The wild grape stone is transparent and detailed in texture, elegant and greasy in light green, and watery and dripping. It looks like the appearance of top-grade ice jadeite, and the price is economical.
It is an orthorhombic system, and the crystals are mostly grape-like, stalactite-like and granular disintegrated bodies. Bright and semi-bright, the colors are yellow-green, brown-yellow, gray, red to colorless. It occurs mostly in the altered igneous rocks such as gabbro and diabase, and is the product of hydrothermal alteration of basic oblique sharp stones. In the market, because the wild grape stone is rare, the merchants who are normally learned or deceived will use the green garnet as a wild grape stone. No, just pay attention to the results of the body, you can distinguish the green garnet and wild grape stone.
Green garnets are usually full of strips and needle-like inclusions, mostly green tourmalines or black tourmalines. Because wild grape stone is produced under the hot water effect of high temperature, it is rarely symbiotic with the minerals produced by low temperature, and the production of tourmaline is absolutely high. Therefore, it is not symbiotic with wild grape stone. . Because, by simply inspecting the condition of the bag body, it is possible to distinguish between the wild grape stone and the green garnet.
Grape stone, the most primary of the yellow-green, red, colorless also received farewell. Because the output is small, the normal price is more expensive.
Grape stone is a kind of semi-precious stone in the sea. There are not many known people. However, "ice jade" believes that it is familiar to itself. Because the color of the wild grape stone is light green and shiny, there are merchants who use it to fake ice jade. The wild grape stone has its own beauty, why rely on the name of "hard jade". The difference between wild grape stone and green blue willow is because the two are green semi-bright semi-precious stones, and the appearance is extremely similar.
I feel that the biggest ones are not the same, but there will be faint light in the wild grape stone leakage, the color is also more moist and slightly green. As for the weight, it is also obvious that there is no similarity. The ratio of wild grape stone is 2.87, which is very close to the crystal. A 10MM bracelet is about 22-29-31 grams, and the ratio of green banana (green garnet) with the diameter of the bead is 3.4-3.6. The weight should exceed 34 grams. Arrived at 38 grams.
The above is the identification method of grapevine for everyone, and I hope that it can be used as a reference for everyone. I know how to identify the grape stone. When you buy, you know how to choose it.
