Sotheby’s To Auction 94-Carat Paraíba Tourmaline
The stone is expected to fetch up to $2.7 million.

The 93.94-carat gem named “The Blue Lagoon” is estimated to sell for 1.3 million-2.5 million CHF, or $1.4 million-$2.7 million.
The stone is a Cuprian tourmaline from Mozambique, which has emerged as not only the world's most productive country for the gemstone, but also as one of the leading sources for top-quality colored stones, according to Sotheby’s. This summer at Sotheby’s New York, a 55.22-carat ruby from the country sold for over $30 million.
Paraíba tourmalines, a variety of Cuprian tourmalines, get their name from the Paraíba region of Brazil where they were first discovered in the 1980s, but the term is now granted to greenish-blue specimens of vivid to deep saturation, regardless of the source.
The variety has become one of the most highly sought-after gemstones in the world, Sotheby’s said, often commanding prices surpassing those paid for fine sapphires, rubies, and emeralds.
Top quality Paraíba tourmalines display an extraordinary electric blue hue but are typically small and have a “significant degree” of internal imperfections.
“[The Blue Lagoon’s] impressive size, superlative clarity, and enchanting turquoise color—all achieved without the aid of heat treatment—recall the crystalline waters of a tropical paradise,” Sotheby’s said.
“The Blue Lagoon” is set in a bespoke high jewelry necklace by the 130-year-old European Maison Adler Joailliers, conceived and created exclusively for this stone. The piece features a waterfall of more than 76 carats of round, marquise- and pear-shaped diamonds.
The Paraíba tourmaline is accompanied by a Bellerophon report brochure and an SSEF report with an appendix attesting to its “exceptional” size and quality. The original sketch of the necklace design is also included.
The auction is part of Sotheby’s Luxury Week, a biannual seasonal series held in Hong Kong, New York and Geneva, offering lots across jewelry, watches, handbags, and accessories.
