True and false aquatic agate

There is a fake

In recent years, with the warming of aquatic agate, the price has been rising, and rare and good aquatic plants have been greeted by many agate lovers. In such a high temperature environment, fake agates are also pouring into this market. What kind of aquatic agate is good? How to identify genuine aquatic plants agate?

The real aquatic agate feels cool, the surface is like a layer of wax, and has a waxy luster, translucent, hardness of Mohs 7, impressed with a knife, because it is a crystalline body formed in the molten state, mostly Globular, so particularly dense; after grinding the surface more delicate, in the hard wood board on the rapid friction more than a dozen, aquatic agate is not hot, the wood is hot; the color is often mixed in a few, forming a beautiful pattern, Layered pattern, Jinhua and other colorful patterns. In addition to artificial synthesis of fake water agate, part of it is made of high quality stone. The basic features are: feel cool, but no waxy feeling and luster, some low hardness, can use a knife to cut out traces; smashing the observation section, except that there is no layered pattern of aquatic agate, the particles are coarse, even Cracked; opaque, distinct lines between colors. Some unscrupulous traders have attached a thin layer of organic matter to the surface of fake agate agate, giving people the illusion of waxy luster and feel. This is particularly noteworthy.

Although modern science and technology are developed, there are many kinds of jade identification instruments. People generally judge the quality of agate and economic value by using naked eye as the main means. Using these instruments in the transaction process is very inconvenient. Second, it cannot be solved. The problem is very simple and will be limited by the environment. If we judge the quality and economic value of agate, then the instrument will be useless. It is impossible to perform complex instrument operations at the transaction site, so visual identification is always an extremely important method. Aquatic agate is usually graded with ribbons, colors, transparency, cracks, impurities, sand centers and block weights, and is generally paired with harmonized raw materials. The true and false selection methods are as follows: (1) Color: The true color of the agate is bright and bright, and the color and light of the fake agate are all poor. The two are more obvious. (2) Texture: The fake agate is mostly imitation of stone, which is softer than the real agate of water plants. The jade can be traced on the fake agate, but the real product is not drawn. (3) Process quality: The production process of high-quality aquatic agate is strict and advanced, so the surface brightness is good, the inlay is firm, and there is no scratch or crack. (4) Transparency: True water grass agate transparency is not as good as synthetic ones. It is slightly chaotic, and some can see the natural water line or “cloud”. The synthetic agate has good transparency and is transparent like a glass ball. (5) Weight: True water grass agate jewelry is heavier than synthetic agate jewelry. (6) Temperature: True agate is warm in winter and cool in summer, and synthetic agate changes with the outside temperature, and it heats up in hot weather. It cools in cool days. (7) The similarities and differences between crystal and agate: The chemical composition of crystal and agate are all silicon dioxide, but there are some differences between the two. Crystal is a single crystal, a crystal is usually a crystal crystal, and agate is a polycrystal aggregate. Under the electron microscope, the agate agate is composed of numerous tiny silica crystals, so the aquatic agate is usually translucent while the crystal is transparent.
