This specimen has no repairs. Most people today associate the Jonas Mine only with the single most famous find here of deep pink tourmaline. However, the mine also produced green tourmaline of high caliber and size. This crystal is a huge single, with sharp termination and excellent form. Note the dramatic surface tone of green, translucent to just a millimeter or so inside, which gives the piece a rippling silky look on the surface. When strongly backlit, it is greener internally as well, and translucent in some parts.
