What is the rarest color of tourmaline? The rarest color of tourmaline is Paraíba tourmaline, a vibrant neon blue or blue-green stone that is highly sought after for its unique and striking color. Discovered in the late 1980s in the Brazilian state of Paraíba, this gemstone’s rarity and captivating hue make it one of the most valuable in the world.
What Makes Paraíba Tourmaline So Rare?
Unique Geographical Origins
Paraíba tourmaline was first unearthed in Brazil, specifically in the Paraíba state, which gave the stone its name. The initial discovery was made in the late 1980s by a dedicated miner, Heitor Dimas Barbosa, who spent years searching for this unique gemstone. The deposits in Brazil are limited, and subsequent discoveries in Nigeria and Mozambique have also been small, contributing to its rarity.
Distinctive Chemical Composition
The vibrant color of Paraíba tourmaline is due to its unique chemical composition, which includes copper and manganese. These elements give the stone its distinctive neon blue or blue-green color. The presence of copper is particularly rare in tourmalines, making the Paraíba variety exceptionally unique.
Limited Availability and High Demand
Due to its limited geographical sources and the small size of most of the stones found, Paraíba tourmaline is both rare and in high demand. Its scarcity and stunning appearance drive its value, making it a prized possession for collectors and jewelry enthusiasts alike.

Identifying Paraíba tourmaline requires careful examination of its color, clarity, and origin. Here are some key identifying features:
- Color: Look for the neon blue or green hues, often described as "electric" or "glowing."
- Clarity: Expect some inclusions, as flawless Paraíba stones are extremely rare.
- Origin: Authentic Paraíba tourmaline should come with certification of its origin, especially from Brazil.

- Rubellite Tourmaline: Known for its intense pink to red hues, often compared to ruby.
- Indicolite Tourmaline: A deep blue tourmaline that is less common than other colors.
- Chrome Tourmaline: A vibrant green stone colored by chromium, similar to emerald.
