7.18ct Vivid Neon Blue-Green (Copper-Bearing) Natural Paraiba Tourmaline RING 18K Gold

Few gemstones command instant recognition like Paraiba tourmaline—celebrated for its copper-bearing chemistry that produces an unmistakable neon blue-green radiance. First discovered in Brazil’s Paraíba region and later found in Mozambique, true Paraiba material remains extraordinarily scarce, prized by collectors for its vivid saturation and luminous presence.

At the heart of this ring is a natural 7.18ct round Paraiba tourmaline displaying a vivid neon blue-green (copper-bearing) color character—an electric hue that reads bright and alive in both daylight and evening light. Though delicate in size, a fine Paraiba’s color can appear larger than its carat weight, thanks to its signature glow.

The setting is crafted in 18K gold (8.2g) and designed for maximum brilliance: 45 accent diamonds totaling 0.23ct in G/VS quality envelop the center with a scintillating, high-jewelry finish. The contrast between crisp white diamonds and neon Paraiba creates a striking, modern-luxe statement.

Offered without a grading certificate, this piece is presented as a refined connoisseur’s jewel—an heirloom-forward ring that pairs rarity with unmistakable presence. An exceptional choice for collectors drawn to copper-bearing color and diamond-forward craftsmanship.
