What is the difference between chalcedony and jade and agate? Chalcedony, jade and agate are often confused. It is really dizzy to see their appearance. The relationship between chalcedony and agate is actually juxtaposed. Both are cryptocrystalline quartzite jade. Chalcedony belongs to the recessive crystal of hydrous quartz, which is very close to crystal, glass to grease luster, and very transparent, but agate is a gel of dehydrated silica, with glass luster, less transparent and chalcedony. . The jadeite is the only jadeite in jade. Let's take a look at the difference between chalcedony, jade and agate. The difference between agate and chalcedony 1, define the distinction Agate: cryptocrystalline quartzite with distinct striation-like structure, and chalcedony, cryptocrystalline quartzite with no obvious band-like structure. That is to say, cryptocrystalline quartz without a strip-like structure and uniform color is chalcedony, and cryptocrystalline quartz with a strip-like structure is agate. 2. Physical property distinction The hardness of agate is 7, the density is 2.60-2.70, the color is quite layered; chalcedony: hardness 7-7.8 degrees, density 2.60-2.66, uniform color. 3. Production area Agate and chalcedony as sister jade will appear in the same producing area, but the yield of chalcedony is not much, of course, it looks more like jade. The color of chalcedony is colorful, and some varieties have strange patterns and beautiful patterns, which is amazing. It conquers the public with its unique beauty. In ancient times, it was the exclusive of the aristocrats and merchants, but now they have entered the homes of ordinary people and become the jade variety of the popular public. But agate is one of the seven treasures of Buddhism, so the effect of agate is much stronger than that of chalcedony, which is unmatched by chalcedony. The difference between chalcedony and jade 1, visual angle distinction What is the difference between chalcedony and jade and agate? Look at the luster: jade and chalcedony are all glass luster, but the emerald's luster is relatively fresh and translucent compared to chalcedony; look at green and color root: jade can see green and radiance The chalcedony is invisible; the green and white boundaries of the jade are obvious, and the color of the chalcedony is uniform, and the color boundary is not obvious; see the internal structure: the interior of the jade is a fiber-interwoven structure, and the chalcedony is a granular structure. 2, tactile angle distinction The density of jadeite is greater than that of chalcedony. The hardness of chalcedony is about 6.5 and the density is 2.58-2.64. The density of natural jadeite is defined between 3.25 and 3.43 and the hardness is 6.5-7. Therefore, the amount of jade will be felt by hand, and the chalcedony is very light. 3, the perspective of hearing Two pieces of chalcedony jewelry collide with each other, making a dull sound. When the two emeralds collide gently, they will make a crisp and long sound. 4, physical properties distinguish The relative density of green chalcedony similar to jade is about 2.6, which is much smaller than jadeite, but small pieces are not easy to distinguish by hand. It must be determined accurately by measurement. The refractive index of the green chalcedony is about 1.54, which is smaller than that of jade. How to buy chalcedony and agate 1. How to choose agate The evaluation and purchase factors of agate are color, transparency and blockiness. The process requirements are bright, pure, thick layer; smooth surface, high transparency; uniform and clear texture, good linearity; fine texture, toughness; no cracks or cracks; Red and blue are the best. 2, how to buy chalcedony The color of chalcedony is pure and beautiful, and the bigger the block, the better. The quality of green chalcedony and green chalcedony is the most precious. The chalcedony is processed into jewelry such as ring faces, bracelets and necklaces.
