The pink color of tourmalines from many fields is the result of prolonged natural irradiation. Some tourmaline gems, especially pink to red colored stones, are altered by heat treatment to improve their color. Irradiation is almost impossible to detect in tourmalines, and does not, currently, impact the value. Heat treatment is also used to enhance tourmaline. Heavily-included tourmalines, such as rubellite and Brazilian paraiba, are sometimes clarity-enhanced. A clarity-enhanced tourmaline (especially paraiba) is worth much less than a non-treated gem.

Jewellery I made for myself
Friday, June 24, 2016
Some jewellery pieces I make with no intention to ever sell them. The reasons are different. In this case the stone is too hard to come across. Well, it is a labradorite cab, you would say, there are tons of them out there. The difference is that this one is actually from Labrador, the area that gave the name to the stone. They find labradorite in many other places now, mostly you see them coming from Madagascar. It is unique for me, anyway. I really enjoy wearing it.

Scientifically called "blue zoisite, Tanzanite was renamed as tanzanite by Tiffany and Co., who wanted to capitalize on the rarity and single location of the gem, and thought that "blue zoisite" (which might be pronounced like "blue suicide") wouldn't sell well. (source)

Copper jewellery started appearing about 7000 years ago. The Museum of Ancient History in Lower Austria found a female jeweller's grave, dispelling the long-held assumption that in ancient times, jewellers were always male. (source)
