What is Paraiba Tourmaline and what its worth for?

Since it was discovered in the late 1980s in Brazil, Paraíba tourmaline’s striking neon blues and greens have electrified the gem world. The gem’s unique, vivid coloring instantly set it apart from other tourmalines. Initial worldwide reception to the gem was wild, especially in Japan, where demand for fine-colored stones was insatiable.Prices for this exotic newcomer—especially top quality in sizes between 3.00 and 5.00 carats—climbed rapidly to over $10,000 per carat. No tourmaline—even prized rubellite reds and chrome greens—had ever achieved such heights in value. Paraíba tourmaline’s rarity undoubtedly contributes to its high prices.(Reference GIA)

 

Where its found?

The gem is an elbaite tourmaline that comes from one area of Paraíba state in Brazil’s northeast corner. Like many other Brazilian elbaites, Paraíba tourmaline forms in pegmatite. But researchers believe that its crystals form under very unusual conditions, with large amounts of trace elements like manganese and copper, which causes its color. Paraíba tourmaline is unusual because, although copper colors some other gems—notably turquoise—it’s not a coloring agent in any other tourmaline. Nowdays Brazil Paraiba is so rare that most of you might not have seen in reality.  Currently Mozambique and Nigeria are large producers of Paraiba Tourmaline almost 99% in market from these locality and belive some of the Mozambique paraiba surpasses Brazil color and clarity.

(Reference GIA).

 

What is the right color of Paraiba Tourmaline and what causes it neon glow?

Paraíba tourmalines appear in a range of greenish blue, bluish green, green, blue, and violet hues. Although buyers covet all these colors, Neon blue and violet have the most appeal. Dealers use a number of names to try to capture the extraordinary quality of Paraíba tourmaline’s colors. Besides neon, they use terms like “electric,” “turquoise,” “sapphire,” or “tanzanite” blue, and “mint” green. the Neon Blue effect caused by traces of copper (CU) the more the cu the better the paraiba color its also called copper-bearing tourmaline.
