A Maine Story
An American Gem
First discovered in 1820 and subsequent finds over the years, it put Maine on the world map as a source for high quality tourmaline gems. A major discovery in 1972 on Plumbago Mountain in Newry, Maine cemented Maine as a significant world source of fine tourmaline gemstones.
Cross recognized the historical significance of this find and began working closely with the miners of these magnificent gems. The close partnership continues today with the ongoing discoveries in Maine’s western mountains.

Window of Opportunity
Nearly fifty years has passed since the major 1972 tourmaline find in Newry, Maine where they found 3.5 million carats of tourmaline crystals. Over the years we bought more than we sold knowing that gem finds don’t last forever. There are now colors, sizes, and shapes that are extremely rare and in some cases no longer available. If you see something you love it’s best to act quickly. There’s no guarantee another like it exists.
Case in point: In 2007 there was a find of tourmaline in Newry, Maine called Eureka Blue. People loved the color. The gems sold quick, but the find was small and the mining only lasted a few seasons. By 2013 all the large Eureka gems had sold. We still get calls from people who are now ready to buy. What they want, however, simply does not exist.
Gem finds are rare, especially in North America. Maine tourmaline is a piece of Maine and American history, it’s a connection to place, an exquisite creation of nature. Today, there is a rare opportunity to own a bit of Maine/American pride and heritage, in choosing a piece of Maine tourmaline jewelry.
