20.23ct Vivid Neon Bluish Green Natural Paraiba Tourmaline NECKLACE 18K White Gold GIA Certified

Among the world’s most coveted colored gemstones, natural Paraiba tourmaline is celebrated for its extraordinary copper-bearing chemistry—responsible for the legendary neon blue-green luminosity first discovered in Brazil’s Paraíba region and later found in select deposits such as Mozambique. Fine, high-carat examples are exceptionally scarce, with demand driven by collectors who recognize its signature “electric” presence.

At the heart of this necklace is a magnificent 20.23ct natural Paraiba tourmaline, fashioned in an elegant oval that amplifies its Vivid Neon Bluish Green (Copper-Bearing) color. The gemstone’s saturated, radiant hue reads as luminous and alive in every lighting condition—an unmistakable hallmark of top Paraiba.

Crafted in 18K white gold (39.6g), the design is richly articulated with 388 accent diamonds totaling 12.62ct (GVS). These diamonds are meticulously set to frame the center stone and add continuous brilliance, creating a refined contrast that intensifies the Paraiba’s glow while preserving a sleek, modern high-jewelry silhouette.

Offered with GIA certification (Report #1232683387) and additional AAP54622 documentation, this necklace is both a connoisseur’s acquisition and an heirloom-grade investment piece—rare in gemstone, bold in scale, and timeless in craftsmanship.
