GREEN TOURMALINE CONSTRUCT
GREEN TOURMALINE CONSTRUCT. Just to be quite clear this is not a natural specimen. It is an example of fakery, aka fake. This is a good bad and ugly specimen. Good is the quality of a beautiful green natural Tourmaline crystals, worth the money. The bad is someone intended to palm this fake off as a natural specimen. It has been glued to conceal a broken crystal and they did a pretty bad glue job too. A typical type of specimen and the location is also renowned for similar fakes. The large green Tourmaline crystals is glued into where another different Tourmaline crystal broke off. All the crystals are real and the big one is great.
This is a construct where a specimen has been glued into a matrix. It was in the collection for many years and originally purchased from a retired dealer. Hopefully you all look at your specimens in particular gem specimens with a 10 x mag and strong light. Also fluorescent UVA and UVB can be helpful in detecting glues. They are well knowledged in their art and sprinkle crystal dust on top of the glue to conceal it. One of the give always on this glue job is the angle is wrong in orientation with the quartz crystal. Repaired specimens are OK (to some people) and always labeled as such repaired or R in the title. This specimen sits freely on a perspex stand.
