Paraiba tourmaline is a rare and highly prized gemstone, renowned for its intensely vibrant and electric blue-green to greenish-blue hues, often described as resembling a tropical sea or neon glow. This unique coloring, unlike any other tourmaline, is due to the presence of copper. Discovered in the Brazilian state of Paraíba in the late 20th century, it has since been found in other locations like Nigeria and Mozambique, though the Brazilian variety is generally considered the most valuable.

Key characteristics of Paraiba Tourmaline:

• Color:

  Distinctive electric blue-green to greenish-blue, with high saturation. The presence of copper is responsible for this signature glow, while manganese can contribute to violet or purple hues.

• Rarity:

  Paraiba tourmaline is extremely rare, especially the original Brazilian material, as deposits are limited and often mined in narrow tunnels deep underground.

• Value:

  Due to its intense colors and scarcity, Paraiba tourmaline is one of the most expensive tourmalines on the market, often commanding high prices per carat.

• Size:

  Faceted Paraiba tourmalines rarely exceed a few carats because the rough material is frequently fractured.

• Origin:

  First discovered in Paraíba, Brazil, it is also found in Nigeria and Mozambique.

• Cutting:

  Paraiba tourmalines are often cut into custom shapes to maximize their sparkle and color, though cabochon cuts are used for specimens with chatoyancy or asterism.
