Cruzeiro Mine Debuts ‘Winter Tourmaline’
The Brazilian mine’s new collection features cabochons in soft, muted shades like silver and lilac.
The Cruzeiro mine debuted its new “Winter Tourmaline” offering at the GJX show in Tucson last month.
Minas Gerais, Brazil—The Cruzeiro mine in Minas Gerais, Brazil, known for its vibrant tourmalines, has launched a new collection of softer-toned gemstones.
The “Winter Tourmaline” collection is made up of cabochons in muted shades, including silver, lilac, and mauve.
The new palette of colors comes from an unexplored section of the mine reached during mining activity last year, the miner said.
"During exploration of the mine, we at times find unusual or entirely new colors. In 2025, a pocket yielded a particular palette that was quite different from the brilliant green and pinkish-red rubellite for which the mine is known," said Douglas Neves, CEO of Cruzeiro Mine.
The miner debuted the new material at the GJX Show in Tucson, Arizona, where it has exhibited for more than 20 years.

"During exploration of the mine, we at times find unusual or entirely new colors. In 2025, a pocket yielded a particular palette that was quite different from the brilliant green and pinkish-red rubellite for which the mine is known," said Douglas Neves, CEO of Cruzeiro Mine.
The miner debuted the new material at the GJX Show in Tucson, Arizona, where it has exhibited for more than 20 years.
The miner said it has noted “a special interest” in cabochons in the United States.
“Prior to our official launch, we tested these new cabochons with some designers in New York, and the silvery and purple shades received particular attention for their versatility, while the reddish tones offer a compelling alternative to our faceted rubellites," said Dr. Adriano Mol, head of brand and product development at Cruzeiro Mine.
The cut showcases the gem’s natural inclusions and translucency, which many designers see as a positive characteristic that gives the stone personality and individuality.
Cabochons are valued for their versatility and offer a commercially accessible product without sacrificing design, the miner noted.
Featuring the cut in signature pieces helps designers stand out in a crowded market, blending artistry with broader appeal.
Cabochons are also a way for miners and cutters who value responsible mining to make the most of their production, the miner noted.
"Cabochons generally have a more competitive price point, so we also see this as a way to offer a product that has all the hallmarks of the mine but is ideal for an emerging designer, or even a way for an established designer to offer a more gem-heavy piece, which is a trend we are seeing due to the rising price of gold," said Christine Puleo Reis, head of U.S. marketing for Cruzeiro Mine.
