The colour range of Paraiba tourmalines - SSEF

Paraíba tourmaline is a rare, copper-containing gemstone prized for its vibrant, "electric" blue-green and greenish-blue hues, sometimes with violet or green shades. Its unique color comes from the presence of copper, which is rarely found in tourmaline. This variety of tourmaline was first discovered in the state of Paraíba, Brazil, in 1989 and is now mined in places like Brazil, Nigeria, and Mozambique.

Key characteristics

Color: The most distinctive feature is its vivid, often neon, colors, ranging from bright blue to greenish-blue, turquoise, and violet.

Chemical Composition: Its unique color is due to the presence of copper and manganese. The copper is what gives the stone its signature look.

Origin: Named after the Paraíba state in Brazil where it was first found, it is now also sourced from mines in Nigeria and Mozambique.

Rarity: It is an extremely rare gemstone, even rarer than diamonds, which contributes to its high value.

Appearance: The colors can seem to glow, even in low light, making them instantly recognizable.

Other properties: As a tourmaline, it is a variety of the elbaite mineral. It can also exhibit piezoelectricity, meaning it can generate an electric charge when heated or rubbed.
