Green tourmaline is one of the colors in which tourmaline gems can be found. This is a good square shaped green tourmaline gemstone with good color. Since we handpick and custom cut every single gem, you do not need to settle for any low grade close out or reject quality gems. The GTN-10 might appear quite similar to a chrome diopside gem, but green tourmaline is much stronger and more durable as compared to chrome diopside. Custom cutting of every single gemstone sold at Directstones means that you can request for green tourmaline or any other gem in the shape and size that you need. A matching green tourmaline matching set can also be cut as per your requirements. We are the trusted and reliable source for even the smallest gem stone buyer and have not fixed any minimum order requirements in terms of volume or value.
