Which type of tourmaline is known for its rarity and vibrant colors?

Paraiba tourmaline is renowned for its striking neon blue to green hues, which are caused by the presence of copper in its chemical composition. This unique coloration is what sets Paraiba apart from other tourmalines, making it particularly prized among collectors and gemstone enthusiasts. The rarity of Paraiba tourmaline is attributed to its limited geographical availability, with significant deposits mainly found in Brazil, and to a lesser extent, in Mozambique and Nigeria. The vivid colors, combined with the gemstone's scarcity, contribute to its high value in the market, solidifying its status as one of the most sought-after types of tourmaline.

While other types of tourmaline, such as rubellite and indicolite, also exhibit vibrant colors, they do not reach the same level of rarity and distinctive appeal that Paraiba does. Morganite, while beautiful and popular, is a different mineral altogether and does not belong to the tourmaline family.
