What is Paraíba Tourmaline? Paraíba Tourmaline is a rare variety of the Tourmaline group, a gemstone characterized by its vibrant neon blue to green and blue-green colors. Brazilian Paraíba Tourmaline, in particular, is highly prized worldwide for its unique fluorescent glow caused by copper (Cu) content. History: Discovered in the late 1980s and debuted on the market in the 1990s. It quickly gained fame for its unique copper-containing color. Similar stones were discovered in Nigeria (2001) and Mozambique (2005) in the 2000s, but Brazilian Paraíba Tourmaline is distinguished by its higher saturation. Market and Purchase (as of 2025) • Price: Brazilian Paraíba Tourmaline is of the highest grade, with prices ranging from $10,000 to $30,000 per carat (approximately ¥1.5 million to ¥4.5 million). High-quality stones of 2-3 carats can fetch $20,000 to $30,000 per carat. As of 2025, the supply is dwindling, and prices are rising (e.g., a 93-carat Mozambique stone in 2023 was estimated at $13,800-$26,600 per carat, while Brazilian stones are even more expensive). Entry-level melee (small stones) can be found starting from a few thousand dollars. Brazilian Paraíba Tourmaline, since its discovery in 1989, is an ultra-rare gemstone that has captivated the jewelry world as a symbol of neon blue. Due to its high price and beauty, it is called the "Rolls-Royce of gemstones" and is ideal for jewelry and collections. Unlike pink beryl like morganite, it is characterized by its striking blue-green color.
