Reply To: Paraiba or Copper Bearing Tourmaline, How can I know?

Hey Terry –

Most any competent gemologist can ID it as Tourmaline. However, you need spectrographic instrumentation (a spectrometer) in order to establish the presence of copper in Tourmaline.

If you check out our “Appraisals” tab we provide a gem identification service that (for our members) is only $55 and our lab can identify cuprian (copper presence) in tourmaline or lack thereof. You could then send it to GIA for their certificate knowing it is indeed copper-bearing tourmaline.
