Tourmaline is the most color-diverse gemstone family, and pricing varies enormously by variety. A neon blue Paraíba tourmaline can sell for $20,000+ per carat while a common green tourmaline might cost $20/ct. Understanding the different varieties — Paraíba, rubellite, indicolite, chrome, watermelon, and more — and their respective value drivers is essential for navigating this wonderfully varied market.

Paraíba Tourmaline: The Crown Jewel
Paraíba tourmaline, colored by copper, is the most valuable tourmaline variety and one of the most expensive colored gemstones. Originally discovered in Paraíba, Brazil in 1989, these neon blue-to-green stones caused a sensation. Brazilian Paraíba tourmalines command the highest premiums ($10,000-$50,000+/ct for fine stones), followed by Mozambican copper-bearing tourmalines ($2,000-$15,000/ct) and Nigerian material. The key to Paraíba value is the electric, neon quality of the color — caused by copper and manganese — which is unlike anything else in the gemstone world.
Rubellite, Indicolite, and Chrome Pricing
Beyond Paraíba, several tourmaline varieties command significant prices. Rubellite (vivid pinkish-red to red) ranges from $200-$3,000/ct for fine quality — stones that remain red under incandescent light (rather than shifting to brown or pink) are most valued. Indicolite (blue tourmaline) ranges from $100-$1,000/ct, with pure blue tones commanding premiums over greenish-blue. Chrome tourmaline from East Africa shows a vivid green colored by chromium and vanadium, selling for $200-$1,500/ct for fine stones. Watermelon tourmaline (pink center with green rind) is valued based on color contrast and appeal, ranging from $50-$500/ct.
