Emeralds and green tourmalines are very similar. Green tourmaline has been exploited for a long time in the history as a typical sample of emeralds. Until the characteristics of tourmaline were gradually discovered, green tourmaline and emerald can There is a very typical way of distinguishing.
There are three main types of green tourmalines: one is a dark green tourmaline, one is a blue-blue tourmaline, and the other is a yellow-yellow-green tourmaline. These three types of green tourmaline are close to the grandmother green color and are dark green tourmalines. The color of the emerald is usually dark green or blueish green.
From this point of view, there is indeed a great similarity between green tourmaline and emerald. However, because the two gemstones have common chemical and physical properties, the emerald and the green tourmaline can be distinguished from the following aspects:
Contrast from the light color texture, the internal light color of the green tourmaline is darker than the emerald, and the contrast between the cut gemstones is more significant. The cut surface of the tourmaline gemstone is deeper, while the emerald gemstone flashes in the turquoise color. With a bright light, the contrast is more energetic!
From the perspective of inclusions, the emerald gemstones have more internal inclusions than the green tourmaline gemstones. Usually, the emeralds on the market have significant internal inclusions, and the green tourmaline is relatively pure in terms of material selection due to the large yield.
From the perspective of gem cutting, emeralds are usually made of typical emerald cuts because of their extremely brittle texture. The green tourmaline gemstones have a lot of cutting methods and the gemstone shape is more abundant.
From this, we can sum up the difference between the green tourmaline and the emerald on the naked eye: the emerald is more green than the green tourmaline, and the light is more lively; the emerald's inclusion is more green than the green tourmaline Many; emeralds are usually emerald-style (square) cuts, while green tourmalines have a variety of cut shapes. After comparing these naked features, we believe that green tourmaline and emerald can also be identified by the naked eye.
Emerald is known as the king of emeralds, it is a very precious gem, so there are many imitations, and there are many gemstones similar to emeralds, such as: calcium garnet, fluorite, apatite, jade, chrome Diopside, etc.; so it is difficult to distinguish. But the foxes that are licking are also exposed. The key differences are: natural emerald anti-white light healing cracks and synthetic emerald smoke-like flux inclusions; synthetic emerald fluorescence effect is more obvious than natural emerald, in dark Use strong light to illuminate the red light.
Because the tourmaline is also more expensive, there are counterfeit goods on the market. There are two types of common imitation products, one is artificially colored with colorless tourmaline; the other is made of red glass. The way to identify is that true tourmaline often has obvious dichroism, visible double shadow; tubular wrap or cotton batt can be seen in the body, and the cross section of the crystal is curved triangle. These characteristics are not found in the imitation goods. The tourmaline dyed by the workers is not difficult to identify because of the color stagnation and the lack of natural tourmaline.
