Tourmaline attracts the hearts of countless mm with its dazzling color tone. It is known as the "Colorful Supreme" and "The Rainbow Falling into the World". Unlike the general colored jewellery, tourmaline has unique and unique ornamental value. It also has a unique effect on women's beauty and beauty because of its special electrical bisexuality. It is such a fascinating colored jewel that has unscrupulous commercial fraud. Imitation of the sale of pseudo-biaks, how to distinguish the identification of tourmaline, set up the necessary homework to choose the tourmaline jewelry.
Among all the gems, the color of the tourmaline is the most abundant, and it is known as the “rainbow gemâ€. Because the homonym of tourmaline is "dispelling evil spirits" and adding colorful features, it has become the most brilliant colored gem in the past two years. The domestic market is like this, what is selling well, and what is fake imitation. Tourmaline is no exception.
From the current information on the market, imitation of tourmaline counterfeit is the most crystal, fluorite, glass products in three ways:
Generally, crystals are not red and green like tourmalines. Purple crystals are more common, but tourmalines do not have this purple only purple. Therefore, it is possible to use the difference in color between the two to roughly discriminate. However, there are also crystal stains, which are not necessarily accurate.
The identification of fluorite and tourmaline can be compared firstly from the hardness. The hardness of tourmaline is 7.5 degrees Mohs, and the hardness of fluorite is only about 4 degrees Mohs. The two can compare the hardness by dashing. Secondly, because of the fluorite The hardness is low, so the luster of fluorite jewelry is far less than the tourmaline; the other is that fluorite is often used as a multi-color material when posing as a tourmaline, and there is no purple in the tourmaline, just as the multicolor of fluorite often appears. There is purple, so this is also an effective means of distinguishing fluorite and tourmaline.
The true and false distinction between glass and tourmaline is most obvious. From the perspective of internal inclusions, there are often small round bubbles in the glass. If you see such a feature, you can basically conclude that the glass is not a tourmaline. There is also a way to pretend to be a tourmaline in glass. That is to use a burst of glass to pretend to be a relatively coarse tourmaline. This type of glass is usually dyed after bursting. Therefore, the color dyes are concentrated in the cracks, and the light transmission is easy to distinguish.
There is also a phenomenon in which glass is used to synthesize a similar faceted tourmaline gemstone, so that the glass surface looks like a tourmaline, but the tourmaline has dichroism and birefringence, which are not available in glass. As long as you carefully observe the contrast, you will find it. Moreover, the tourmaline, which is generally used as a gemstone, is certified. The glass of the tourmaline does not have a formal certificate.
