Paraiba tourmaline ring brazilian neon

The Paraíba tourmaline ring showcases one of the world's rarest gemstones, famous for its electric neon color and Brazilian origin.

About this subject

Paraíba tourmaline was discovered in 1989 at the Mina da Batalha in the state of Paraíba, Brazil. Its vibrant neon blue color, ranging from pool blue to emerald green, is caused by the presence of copper in its chemical composition. This characteristic makes it unique among tourmalines and highly valued in the gemstone market.

The rarity of this gem is so significant that its price per carat surpasses that of many diamonds. Since its discovery, less than 50 kilograms of gem-quality Paraíba tourmaline have been extracted. Crystals are typically small, with most weighing less than one carat, making pieces like rings with stones over two carats true rarities.

Secondary deposits have been found in Rio Grande do Norte (Brazil) and later in African countries such as Mozambique and Nigeria. However, Brazilian gems remain the most coveted for their intense color and purity. The original Brazilian mine is now depleted, but the trade in older stocks of Brazilian stones still involves millions of dollars.

In gemological terms, Paraíba tourmaline has a hardness of 7 to 7.5 on the Mohs scale, making it suitable for everyday jewelry, though care is needed to avoid scratches. It typically undergoes no heat or chemical treatments, preserving its natural beauty. The gem is cut with facets to maximize its sparkle and color, and is widely used in high-end rings, necklaces, and earrings.
