3.71ct Vivid Neon Copper-Bearing Blue Natural Paraiba Tourmaline RING 18K White Gold Guild Certified

Few gemstones command the same reverence as natural Paraiba tourmaline—celebrated for its copper-bearing chemistry and unmistakable neon blue-to-blue‑green radiance. First discovered in Brazil’s Paraíba region and later found in Mozambique, fine Paraiba remains exceptionally scarce, prized by collectors for color intensity and electric presence.

At the heart of this ring is a 3.71ct natural Paraiba tourmaline, fashioned in an oval cut to maximize its vivid neon copper-bearing blue color. The stone’s lively saturation and light performance create a striking “lit-from-within” effect that defines top-tier Paraiba.

Crafted in polished 18K white gold (6.2g), the setting frames the center gem with 108 accent diamonds totaling 0.79ct (SI/H), adding crisp scintillation and refined contrast. The meticulous diamond placement and bright white metalwork keep the focus on the Paraiba’s rare hue while delivering an elegant, high-jewelry finish.

This piece is Guild certified (Report No. GU 3113805369), offering added assurance and documentation for long-term stewardship. A distinctive heirloom and a compelling addition to a rare-gem portfolio, it’s designed to be worn now and treasured for generations.
