Product｜Green Tourmaline・Tourmaline・Green Tourmaline Quality｜High-quality transparent green tourmaline from Congo (Cango) stands out for its transparent and fantastic color changes, showing charming shades of yellow, green and blue depending on the angle of light. The high-priced green tourmaline on the market is represented by this type of tourmaline with color depth and changes (see the video below). The value of this type of tourmaline lies not only in its color, but also in the clarity of the gemstone. For example, this one has reached the flawless (FL) grade, and no inclusions or flaws can be found even under a 10x magnifying glass. It is a top-level collection. Many low-clarity blue or blue-green tourmalines can be found on the market. Although the color seems good, the value is greatly reduced due to the cracks. The square emerald cut adds to its elegance, perfectly showing its 1.71 carat green brilliance, making this gemstone highly sought after in the market. The scratch resistance of Mohs hardness 7.5 is quite strong. There is no big problem for daily wear, but the toughness is not good, so you still need to be careful to avoid collisions.
