SparHawk – Mint Green Teal is a bright lively green tourmaline recently found in a farmer’s field just 28 miles north of our store.

Maine is legendary for the watermelon tourmaline found in our western mountains. Most famous was the 1972 find when huge single crystals possessing both pink and green yielded an amazing array of gems.

Blue is the rarest color of tourmaline both here in Maine and around the world. We have a select group of remaining Eureka Blue tourmaline jewelry from the 2009-2010 find.
