What Is Paraiba Tourmaline? The Rarest Blue-Green Gemstone
TL;DR: Paraiba tourmaline is a rare tourmaline variety prized for an intense, neon blue-green colour caused by trace copper content — unlike any other gemstone's colour. First discovered in Brazil in the late 1980s, fine paraiba is among the rarest and most expensive coloured gemstones, often exceeding sapphire and emerald prices at comparable sizes.
What Makes Paraiba Tourmaline Different
Most tourmaline colours come from iron, manganese, or chromium. Paraiba's distinctive neon blue-green to turquoise colour comes from trace amounts of copper (and sometimes manganese) in its crystal structure — a combination that produces a saturation and glow that genuinely doesn't resemble any other gemstone's colour, often described as having an almost electric quality.
Origin and Rarity
Paraiba tourmaline was first discovered in Brazil's Paraiba state in the late 1980s, and the original Brazilian deposits are now largely depleted, making early Brazilian material extremely rare and valuable. Similar copper-bearing tourmaline has since been found in Mozambique and Nigeria, which is more available but still considered rare and commands strong prices, particularly at larger sizes and the most saturated colours.
Durability
Tourmaline rates 7–7.5 on the Mohs hardness scale — a reasonably durable choice, comparable to emerald, though it benefits from a protective setting and reasonable care rather than being treated as diamond-tough.
What Drives Price
Colour saturation is the primary value driver — the most intense, saturated neon blue-green stones command by far the highest prices. Size matters considerably too, since larger fine-quality paraiba is exceptionally rare; prices rise steeply above one carat.
