While discussing some other fraudulent items coming out of Pakistan, Aisha from Rocks-A-Holics told me about the color change in some tourmaline crystals when irradiated. You can take crystals that have little to no color, very pale crystals and zap them, creating a marked increase in the color of the crystals, turning bright pink. The color fades over time and very quickly when exposed to sunlight.
While scanning eBay we came across this item you can find the original auction HERE AT THIS LINK
Take a look at these photos below. If you saw a selection of tourmaline crystals with great color, you could let imagination take hold and convince yourself they are legit. However, like these photos show, the quartz associated with the tourmaline is pitch black, a clear indication that the crystals have been irradiated. In fact, the color is so strong, we would guess that this lot is still giving off radiation, or “hot”. Much like irradiated blue topaz, we don’t say these crystals are now worthless, they are simply poor quality material enhanced by man and not worth as much as a natural crystal with similar color.
When shopping for tourmaline and other gem crystals, remember, super rich hues from crystals that are for sale from dealers who are not well known, chances are, they might have some sort of treatment.
