Phillips New York jewels sale led by rare paraiba tourmalines

Paraiba tourmaline has become the gemstone that stops a room: a neon blue-green flash shaped by copper, sometimes manganese, with enough intensity to make a ring or pendant feel less like adornment than a signature. Phillips is leaning into that magnetism in its New York Jewels sale on June 10 at 12 p.m. ET, where five paraiba tourmalines lead a roster that also includes rare gemstones, important diamonds and signed jewels from major houses.

The headline stones set the tone. Lot 82 is a 31.77-carat paraiba tourmaline and diamond ring estimated at $550,000 to $650,000, accompanied by an SSEF report stating that the stone is of Mozambique origin and shows no indications of heating. Lot 88 is a paraiba tourmaline and diamond pendant necklace estimated at $200,000 to $300,000, with a Brazilian stone that has no indications of treatment. Together, the two lots alone push the headline paraiba estimate past $1 million. Dianne Batista, Phillips’ Head of Jewels in New York, said the season’s auction celebrates the "extraordinary beauty and rarity" of colored gemstones, with paraiba tourmalines at the forefront of collector interest.

That interest has a deep geological logic. GIA traces paraíba tourmaline to Brazil’s Paraíba state, where it was first discovered in the late 1980s, then later to Nigeria and Mozambique. The stone’s saturated blue-to-green color comes from copper, with manganese often contributing to the hue, and Brazilian production has remained sporadic and unable to keep pace with demand. Much of the finest Brazilian material has already migrated into museums or private collections, which is exactly why a Brazilian-origin pendant carries so much weight.

Phillips has also framed the sale as part of a larger story that links Brazil and Mozambique through geology, and the market has already shown how broad the category can be. Earlier Paraíba-type pieces have ranged widely in value, including a Hong Kong necklace with 33 oval Paraíba tourmalines that sold for HK$77,400. That spread is the point: in paraiba, provenance, treatment history and color saturation can matter as much as carat weight, and the result is a gemstone that now reads as both status object and sentimental token. In the current market, few stones are more immediately legible, or more desirable, than that electric blue-green glow.
