Yes. This lot includes facet-grade rough with transparent to Si to VVS clarity pieces. Individual crystal size is under 1 gram, yielding small size tourmaline loose stones.
Q: What is the difference between green tourmaline and indicolite?

Q: Is Afghan tourmaline considered high quality?
Afghanistan is a recognized source of fine tourmaline, particularly from the Kunar and Nuristan provinces. Afghan material is known for its color saturation and crystal clarity, making it sought after by lapidaries and collectors.
