This is a beautiful gemstone. Now that I have gotten that out of the way, this gemstone feels Afghanistan. I think I purchased it in my last significant lot of green tourmaline from anywhere. The squarish cut is unusual, but it shows off the brightness and transparency of this high grade stone extremely well. The two colors that mix well are a bluer green and a grassy green, pure Afghanistan. The clean stone weights 2.87 carats and would make a great ring for special occasions.
