Another unexpected copper discovery with my spectrometer that is in a much more desirable (expensive) color, minty blue/green. The eye clean stone has a very bright, medium light pastel color, but really does not have the neon look to me. Because of it copper content and color, it could be called a paraiba type gemstone by the trade since there is no mention of neon look in the definition. Still I have hear of reports that some cuprian from Paraiba in Brazil do not really have the neon look and I have certainly seen it in my tourmalines. Without the neon look, I don’t think that gemstones should have an increased value for their copper content. Be that as it may, I like this minty want to be and it catches my eye at 3.10 carats.
