QUALITY ROUGH
PRASIOLITE -PARASIOLITE
This is natural amethyst from brazil treated to show a green hue.This is a very clean stone and it will be a delight to cut. I hand slected this rough out of a large parcel as not all rough treats this beautiful dark colour.
The weights and size below are approximate.
During that annealing process, some particular Amethyst specimens, originating from some particular regions of the world, will show a change in color toward the greenish hues instead of transforming themselves into yellow crystals.
That unusual property has been exploited lately by the jewelry manufacturers and sellers in order to produce large quantities of artificial, i.e., synthetic variations of this mineral. Such man-made prasiolite is almost impossible to distinguish from the real, natural stones, although some sophisticated methods have been developed recently.
