What is true crystal? Teach you how to identify (Figure)
The ancient poem describes the bird's ice-cold jade mirror, and the wind knocks on the crystal. "There are ice-brain, cherry-drop crystal." The verses all describe the beauty of crystal, and the crystal refers to the colorless and transparent. Silica crystal, a valuable ore. Nowadays, it is included in the category of colored gemstones in parallel with iced chalcedony and tourmaline, and the yield is small. It is called "water jade" and "water essence" in ancient times. Nowadays, we can often see crystal jewelry, but how do you tell the true and false crystals on the market? Today, Xiaobian will introduce you how to distinguish between true and false crystals. Touch the crystal with your hand. Natural crystals usually have a much cooler temperature than synthetic crystals. For a monochromatic crystal such as amethyst citrine, it is usually necessary to observe its dichroism. Even a good amethyst citrine has a color difference. This method can be used to identify whether or not to add color. Seeing: Natural crystals are often affected by environmental influences during the formation process. When viewed from the sun, you can see a faint uniformity of fine stripes or catkins. The fake crystals are often smelted with crystal slag and glass slag. After polishing and coloring, there is no uniform streaks or catkins. Tongue: Even in the hot summer days, using the tongue to lick the surface of the natural crystal, there is a cold and cool feeling, as well as a touch of fragrance. Fake crystals have no cool feeling. Illumination: The natural crystal is placed vertically under the sun, and it can give off beautiful brilliance from any angle. Fake crystals can't. Hardness: The hardness of the natural crystal is large. Use the gravel to gently stroke the ornament, leaving no trace; if there are streaks, it is a fake crystal. Check with a magnifying glass: Under the transmitted light with a ten-fold magnifying glass, the bubble can be found as a fake crystal. Check with hair: only for round crystal balls. Put the crystal ball on a hairline, and the human eye can see the double shadow of the hair through the crystal, it is a crystal ball. Mainly because the crystal has birefringence. However, this does not distinguish between natural crystals, crystals and smelting crystals. Only distinguish other substances such as glass. Use the thermal conductivity meter to detect: adjust the thermal conductivity meter to the green 4 grid test gemstone, the natural crystal can rise to the yellow 2 grid, while the fake crystal does not rise, when the area is large, it rises to a yellow grid. The above is the resolution method of true and false crystals. Next time, if you buy crystals, you may wish to try out the several methods introduced by Xiaobian. It is not difficult to distinguish between natural crystals and fake crystals.
