Product｜Rubelle・Red Tourmaline・Quality｜This is a red tourmaline from Congo, Africa. Rather than calling it a red tourmaline, I think it is a "red tourmaline" because it has a very obvious bichromatic nature of tourmaline, that is, its spectrum covers a range of colors from purple to purple, which changes according to different light sources. Its clarity is very good, and no flaws inside or outside the gem can be seen by the naked eye. The clarity of this color of red tourmaline is usually very poor, so this part is very rare. We must emphasize again that the current price of tourmaline is very high. Other low-priced tourmalines sold in the market, our US headquarters confirmed that many of the incredibly low-priced tourmalines are indeed quartz and glass imitations. In particular, tourmalines that are fired and polished after quartz are very similar to real tourmalines, and also have some characteristics and feel of gemstones, which consumers cannot identify at all. Currently, the newly mined green tourmaline, a carat of good quality, is more than $100. Green tourmaline is the lowest price among all varieties of tourmaline. So you can imagine that the prices of yellow, red, blue...etc. are even more incredible. Tourmaline belongs to the category of tourmaline and is ionized. This property was widely used in industry in the 19th century. In ancient times, various cultures also used tourmaline for feng shui to ward off evil spirits. Currently, it is one of the gemstones that everyone loves, and some of them are even more expensive than sapphires. Tourmaline is extremely hard, with a Mohs hardness close to 8, but it is brittle, so be careful of damage and breakage at the corners. Clarity｜VS1 - Based on the clarity standards used by GIA for diamonds, the clarity of this gem is still invisible to the naked eye of viewers with standard vision, but if a 10x magnifying glass is used, the inclusions or external flaws of the gem (if any) can be seen.
