Designed entirely from scratch as a full custom order, this ring centers on a natural Paraiba tourmaline set in a delicate 18-karat white gold band. Prized for its vivid turquoise-blue glow, Paraiba tourmaline ranks among the rarest and most coveted gemstones in fine jewelry. The center stone weighs 0.09 carats and measures approximately 2.5 millimeters wide, with official carat weight engraved on the piece.
The band itself is a slender 1.2 millimeters wide in K18 white gold, giving it a subtle, understated profile that sits comfortably on the finger. The gold purity is also officially stamped. This one comes in Japanese size 9 and includes its original presentation case and box.
Purchased by the seller as a collection piece, this ring was tried on only once after arrival and has otherwise been kept untouched in a private gemstone collection ever since. It remains in unused, brand-new condition, a rare chance to own a fully bespoke Paraiba tourmaline design without the custom order wait.
