The tourmaline is rich in color and is the most colorful gemstone in natural gemstones. There are many similar gemstones. For example, gemstones similar to red and pink are ruby, red spinel, spodumene, orange red topaz, and red green stone. Blue citrine-like gems have blue spinels; gems similar to green tourmalines have chrome-containing diopside, emerald, green-green sill, etc. The primary difference between tourmaline and these gems is its unique thermoelectricity, ie After the conflict of the tourmaline on the soft cloth, the heat generated can absorb the adjacent paper dust, plus the strong dichroism and the remarkable ridge double shadow. These characteristics are not found in other gemstones. So through these two points, it is basically possible to distinguish the tourmaline from other gems. However, there are some other materials that counterfeit tourmalines have similar characteristics to tourmalines, such as two-color crystal, glass, fluorite, which requires a little attention.

The difference between crystal and tourmaline is mainly to see their color. Generally, crystal has no red and green like tourmaline. The contrast of crystal purple is common, but tourmaline does not have this purple only purple red! Therefore, it is possible to use the difference in color between the two to roughly distinguish between true and false. The composition of the crystal has the unique thermoelectric effect of the tourmaline. Its two ends are brownish green and brownish red, the color is dark, with gray color, and the two color boundaries are clear. There will also be a strip of straight ribbon. The birefringence is small, and the low-edge double shadow does not have a clear vision. In addition, the two colors are not as clear as the tourmaline.

The glass has a variety of bright colors and the surface is somewhat similar to the tourmaline. The true difference between glass and tourmaline is most obvious. From the perspective of internal inclusions, there are often small circular 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 kind of glass is usually dyed after bursting. Therefore, the color dyes are concentrated in the cracks, and the light transmission observation is easy to distinguish. !

There is also the use of glass to form the appearance of 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! Just watch the comparison carefully and you will find it! And usually the tourmaline as a gemstone is certified, and the glass of the tourmaline will not have a formal certificate.
