Paraiba tourmaline is among the rarest gemstones on earth. Discovered in the late 1980s in the Brazilian state of Paraíba, these stones owe their electric blue-green glow to trace amounts of copper, a phenomenon found in virtually no other tourmaline on the planet. At 19.58 carats, certified by the GIA under certificate number 2547742106, this center stone is a genuinely exceptional specimen. Stones of this size and saturation rarely appear on the open market. The color is vivid, immediate, and entirely natural.

The mounting does full justice to the stone. A double halo of white diamonds surrounds the Paraiba in a bezel-style setting, with intricate open-work filigree visible on the reverse, the kind of detail that signals handcraft and serious goldsmithing. A pear-shaped diamond connector bail flows into a diamond-set wheat and laurel link chain carrying an additional 6.23 carats of round brilliants. The combined diamond weight across the entire piece totals approximately 6.58 carats. Set in 18k white gold, the cool metal is a deliberate choice: it amplifies the neon blue-green of the Paraiba rather than warming it toward yellow. The piece weighs a substantial 51.4 grams, and the presence in person is considerable.

At 18 inches, this necklace sits at the collarbone, exactly where a stone of this magnitude reads best. It is a collector's piece in the truest sense. Paraiba tourmalines of this carat weight with GIA provenance represent a finite supply; production from the original Brazilian mine is essentially exhausted, and comparable stones continue to appreciate in value year over year. For someone acquiring fine colored stones as both wearable art and a long-term store of value, very few pieces at any price point can match what this necklace offers.
