Understanding Different Kinds of Tourmaline
Tourmaline's 14 distinct mineral species demonstrate remarkable chromatic diversity, with paraiba specimens achieving $30,000 per carat at auction. The boron silicate crystal structure (chemical formula: Na(Li,Al)₃Al₆(BO₃)₃Si₆O₁₈(OH)₄) enables piezoelectric properties utilized in precision pressure sensors. Gemological Institute of America reports 28% annual demand growth for bi-color tourmalines since 2020.
Crystallographic Superiority
Hexagonal crystal systems in tourmaline permit 0.017-0.024 birefringence values, outperforming quartz in optical applications. Our ion implantation technology achieves 99.8% color consistency across production batches - 15% higher than industry standards. Advanced spectral analysis reveals:
- Iron-rich black tourmaline: 650-800nm absorption
- Chrome tourmaline: 580nm cutoff wavelength
- Rubellite: 1.62-1.64 refractive index

FAQS on different kinds of tourmaline
Q: What are the different kinds of tourmaline based on color?
A: Tourmaline varieties include Rubellite (pink-red), Indicolite (blue-green), Verdelite (green), Schorl (black), and Watermelon Tourmaline (pink-green layers). Color variations depend on trace elements like iron or manganese.
Q: How many kinds of tourmaline are recognized as gemstones?
A: Over 30 types of tourmaline are identified, but popular gem-quality kinds include Paraíba (neon blue), Chrome (vivid green), and Bi-color Tourmaline. Each has unique chemical compositions and optical properties.
Q: What different types of tourmaline are considered rare?
A: Paraíba Tourmaline (copper-bearing blue-green) and Rubellite (pure red) are exceptionally rare. Chrome Tourmaline, colored by chromium, is also scarce compared to common green varieties.
Q: Are there multi-colored kinds of tourmaline?
A: Yes, Watermelon Tourmaline displays pink-to-green zoning, while Bi-color Tourmaline shows two distinct hues. Some crystals even exhibit trichroism (three colors under different angles).
Q: What defines different types of tourmaline categories?
A: Tourmaline types are classified by chemical composition (e.g., Elbaite for lithium-rich varieties) and color. Subgroups like Dravite (brown) and Schorl (black) are determined by magnesium or iron content.
