Multicolor Tourmaline from The Congo. 4.6 Grams.
Occasionally, Tourmaline has been found to grow in running water. It's pretty rare for this to happen.
The running water polishes the tourmaline as it grows giving the surface a matte smooth texture.
I was lucky enough to get a small find of river tumbled tourmaline from The Congo.
This one is mostly green with bands of pink and yellow at the termination.
