Comments

Paraiba is a green variety of tourmaline containing copper (Cu)
and manganese (Mn). The name is derived from the
Brazilian locality Paraiba where this gemstone was first
mined, however today it may come from a number of localities.

Paraiba tourmaline is commonly heated to improve its
color. There is currently no scientific method available to
determine whether this gemstone has been enhanced or not.
