How does Amethyst distinguish true and false? Natural amethyst has a certain dichroism and birefringence, which is unmatched by ordinary smelting crystal (artificial amethyst), but there are still many difficult to identify true and false amethyst. Let's find out how to identify amethyst. .
At first glance, it refers to the whole state of amethyst. Generally speaking, the surface of natural amethyst is smooth and lustrous, the crystal color is not uniform, and it is agile and vivid. The smelting amethyst has a single color, lacks luster and lacks agility. With vividness.
The second touch means to feel the cool touch of natural amethyst with the first touch; the natural crystal will have a cool feeling when it touches the first time in spring, summer, autumn and winter. This is the difference between melting amethyst (artificial amethyst) and natural purple. The most basic feature of crystal, the smelting crystal feels like glass.
Three photos, refers to the natural amethyst to the sun, from different angles can see amethyst has a different color, ranging from purple to blue, the color is mainly affected by the color characteristics of the body color and body color depth Real natural amethyst will find dichroism in the morning light and sunset. In addition, you can also use a hair silk test to put a hair under the amethyst. The natural amethyst can be clearly seen through the naked eye. The obvious difference in smelting amethyst is that natural amethyst has birefringence, while smelting amethyst does not.
Four colors means that the amethyst of the same crystal is pleochroic, its purple color can be from light purple to deep purple, with different degrees of brown, red, blue, and the vomiting light purple variety has only weak multicolor. Sexual, light brown purple-light purple, dark amethyst can have red-purple-purple, blue-violet-purple two types of chromaticity; while smelting amethyst is single color, no matter from what angle The colors are more uniform, and people can see the clue at a glance.
The five crystals are judged by observing the internal structure of the amethyst. The natural amethyst usually has natural ice cracks or white cloud impurities, and there will be a gas-liquid two-phase inclusion. The smelting crystal usually has small bubbles and raises Crystals have growth lines, while those with glue and cotton are natural amethysts.
Six specific gravity refers to the weight of amethyst in the same size and size. Generally speaking, natural amethyst is called glass, plastic, acrylic and other imitations, but it is difficult to avoid crystal growth, because the weight of crystal and natural amethyst The types are almost the same, and it is not easy to find true and false by hand test. Here, we must use the fifth point to see the crystal to distinguish.
Seven prices refer to the same size and size, which looks like the same quality amethyst. If the crystal and other indicators are similar, but the price is very attractive, here we must be careful whether it is smelting crystal, generally smelting amethyst The lowest price, followed by the crystal, the highest is the natural amethyst, usually, the natural amethyst color is generally 10 yuan / gram, a good point of 15 yuan / gram, a good point of 50-60 yuan / gram The crystal is very transparent. I want the price of impurities without batt to be difficult to estimate; and the melting of amethyst or crystal is usually a string or a price to sell.
As for how to discern the relevant knowledge of amethyst, I would like to say so much to everyone, I hope that the above sharing can help you.
