4. Color: The color of tourmaline can range from deep green to vibrant pink or red, and even blue or black. The color variation is due to trace elements present in the crystal structure of the gemstone.
5. Cut: Tourmaline can be cut into various shapes such as oval, round, pear, emerald-cut, or fancy shapes depending on the design and the natural shape of the rough stone.
6. Style: Tourmaline rings can be found in a range of styles to suit different tastes, from traditional and vintage-inspired designs to modern and minimalist looks.
