Tourmaline, a crystalline boron silicate formed through intense hydrothermal activity, boasts a remarkable array of colors and combinations unmatched by any other natural mineral. However, this diversity can pose challenges in identification. Yet, by closely observing key characteristics, you can often make a confident determination.
Procedures
Inspecting Your Sample
- Immediate differentiation between prismatic and other structures is feasible upon observation.
Consult a gemologist to accurately identify your specimen. Search for a gemologist near you for specialized testing.
Understanding Different Types of Tourmaline
Identify smooth, black specimens as schorl. Schorl is the most common tourmaline type, often found in association with rocks.
Label brown tourmalines as dravite. Dravite typically appears in shades of brown and emits a golden aura under UV light.
Differentiate between uvite and dravite with careful observation. Uvite may exhibit lavender, blue-green, or copper hues.
Spot vibrant colors as a sign of elbaite. Elbaite, found in various colors, is highly valued and sought after.
Note: Elbaite tourmaline holds significant value among collectors.
Watch for the striking blues and greens of paraiba. Paraiba, discovered in the late 1980s, commands high prices due to its rarity.
