Identifying Green Tourmaline: A Step-by-Step Guide
Identifying green tourmaline requires careful observation and consideration of several factors:
1. Color: Observe the gemstone’s color under different lighting conditions. Genuine green tourmaline will display a consistent green hue, regardless of the lighting.
2. Transparency: Check the gemstone’s transparency by holding it up to a light source. Transparent tourmalines allow light to pass through clearly, while translucent or opaque stones may appear cloudy or opaque.
3. Hardness: Test the gemstone’s hardness using a mineral hardness kit or a simple scratch test. Genuine green tourmaline should resist scratching by materials with a hardness of 7 or less.
4. Cleavage: Examine the gemstone for any signs of cleavage. Green tourmaline typically exhibits poor cleavage, meaning it tends to break in irregular directions rather than along specific planes.
5. Luster: Observe the gemstone’s luster under bright light. Genuine green tourmaline typically displays a vitreous luster, characterized by a glass-like shine.
6. Specific Gravity: Measure the gemstone’s specific gravity using a hydrostatic balance or a specific gravity scale. Genuine green tourmaline typically has a specific gravity ranging from 3.02 to 3.26.
