Tourmaline paraiba - 4.64 ct - International Colored Gemstone Association (ICA GemLab) - Neon Paraiba

Paraiba tourmaline stands out in the gemstone world for its intensely vivid neon blue to green colors, attributed to copper content within the crystal structure. The 4.64 carat specimen noted here, certified by the International Colored Gemstone Association (ICA GemLab), exemplifies this striking neon quality described as 'Neon Paraiba.' First discovered in the Brazilian state of Paraiba in the late 1980s, these stones quickly became highly coveted for their electric coloration and rarity. The vivid hues can vary from intense blues to bright greens and are often enhanced by cutting to maximize brilliance. Due to their rarity, Paraiba tourmalines often command premium prices, and their unique color makes them standout pieces in any gemstone collection or jewelry design.
