There is no such thing as "Paraiba Color". Paraiba is a particular location in Brazil where copper bearing Tourmaline was first recognized. There have since been other deposits in Africa found that are also copper bearing.

The stone pictured are normal indicolite Tourmaline, with zero copper content.

If your into these types of tourmaline pencils, spend your money. They look like abundantly found Afghanny closed axis material to me and not worth my $135 but your not spending my money. There smaller than the pics are depicting them as. JM2c.

Thank you. I'm not experienced in purchasing specimens but I want to have some in my collection and to study. I have purchased loose cut rubalites but that's where my education with purchases go. How should I go about getting rough specimens for studies that aren't just cast aways?

Good to know. I'm learning a lot here. Trying to broaden my horizons . I want specimens to study and collect.

Yep. I concur. They are varieties of indicolite. Copper did not cause that color.

My guess is strong backlighting to make the color look a lot brighter than it is.

Yep, I agree again. The pictures look like puffing to me.
