The various gemstones in the colored gemstones are endless, and the dark horses are grouped up. But it is said that today's popular and hot, the Bibi is one of the masters of the gem world. I believe everyone will not oppose it. The tourmaline has many colors, luster, moderate price and health effects. These are the reasons why the tourmaline is no different. But in the colored gem world, no matter how natural or artificial, and the types of gemstones similar to tourmalines, how many? The reason why the tourmaline is prosperous is that it has its uniqueness. Don't admit it when you buy it. The difference between tourmaline and similar artificial gemstones The artificial gemstones similar to the tourmaline are mainly composed of various colored glass and artificial red sapphire. It is easier to distinguish them. The glass is homogeneous and there is no refracting double shadow. The glass has a low hardness and a low density. Tourmaline is two-color and dense. Artificial red sapphire is similar in nature to natural red sapphire, and is mainly distinguished by density and refractive index. When you need to pay attention to the purchase, the tourmaline bracelet or bead chain may be mixed with some low-quality beads such as inferior crystal or agate. These low-grade beads with color tend to be less transparent than the tourmaline, and the brightness is not comparable. Tourmaline. (The picture shows the texture glass) The difference between tourmaline and similar natural gemstones Similar to the red tourmaline, there are rubies, red spinels, spodumene, light red topaz, red beryl, and lilac crystal. Gemstones similar to green tourmalines include diopside, emerald, and green beryl. A gemstone similar to the blue tourmaline has a blue spinel. (red topaz) The difference between the tourmaline and the above-mentioned gemstones is that there are obvious double shadows at the corners of the tourmaline. The gas-liquid inclusions and cracks are more, and the dichroism is strong. It is an extremely important feature of the identification of tourmaline. The transparency is good, and the density and refractive index are better. Large difference, large birefringence. The most reliable way to identify them is to measure density and refractive index. (red tourmaline) The misunderstanding of green tourmaline and emerald Tourmaline has the richest color in the natural single crystal gemstone and is called the "king of color". The mineral name of the tourmaline is called tourmaline. In fact, it was discovered and used very early, but it may have been treated as an emerald in the first place, so it was not recorded in the early gem literature. (emerald) In 1674, Brazil had produced green tourmaline, because its color is very similar to emerald, and it was mistaken for emerald. The mountain is called "Emerald Mountain". Green tourmaline and blue tourmaline have been mined for many years, but so far no emerald production has been found. It is concluded that the earliest discovered emerald is probably the tourmaline. In the 17th century, Brazil's dark green long columnar tourmaline exported to Europe was called "Brazilian emerald." In fact, black tourmaline was known as early as the 16th century, and in 1768, Swedish scientists discovered the relationship between the black tourmaline and the green variety (green tourmaline). (green tourmaline) Tourmaline's simple maintenance knowledge In addition, the maintenance of tourmaline is also very particular, the tourmaline is hard, but the sex is more brittle, and the inside of the crystal is more common. To this end, tourmaline should especially avoid bumps. Never wash the tourmaline in high temperature water or bake it in the fire. This will easily cause the inner body of the tourmaline to expand, causing cracks in the tourmaline. Be sure to remove the tourmaline jewelry when taking a bath or laundry to avoid damage to the tourmaline caused by hot water.
