6.51ct Vivid Neon Green-Blue (Copper-Bearing) Natural Paraiba Tourmaline NECKLACE 18K Gold GIA Certified

Few gemstones ignite desire like Paraiba tourmaline—celebrated for its unmistakable copper-bearing “neon” radiance and a story that began with its discovery in Brazil’s Paraíba region, later echoed by finds in Mozambique. This signature glow, paired with extreme rarity, places Paraiba among the most collectible colored stones in fine jewelry.

At the heart of this necklace is a natural 6.51ct pear-shaped Paraiba tourmaline displaying a vivid neon green-blue (copper-bearing) color. The pear silhouette elongates the look on the neckline, while the gemstone’s lively saturation creates that sought-after electric presence under a range of lighting.

Set in luxurious 18K gold (9.5g), the design is elevated by 30 accent diamonds totaling 0.82ct (GVS). Their crisp scintillation creates a striking contrast against the Paraiba’s saturated hue, delivering a high-jewelry finish with exceptional light return and polished craftsmanship.

Offered with GIA certification (Report No. GIA 7501071217), this necklace is both a wearable work of art and a legacy acquisition—an heirloom-grade piece that showcases a gemstone category prized by collectors worldwide.
