i have been reading on a number of threads about finding stones that are "copper bearing". Why is this talked about? is it because it affects the color? But what if a touramline (or whatever stone) has a beautiful glowy blue/green color, but doens't have copper? Is that less desirable?
Also, does "copper bearing" = cuprian? (I know the element name of copper is cupric/CU, but not sure if these were meant to mean the same thing?)
Thanks so much! So much to learn!
