Description

I found this one of specimen with a gem dealer who could not fix the locality because he had never seen such a combination before. The 6.5cm cluster consists of very stable hard and lustrous noodle like worms on surface and when flipped over reveals the underlying green tourmaline structure encapsulated by massive translucent white chalcedony. Aside from the massive tourmaline you will notice fine green needle like crystals within the chalcedony mass, these extend upward to the surface. 

On the display side you will see these needles as the base structure upon which the chalcedony has crystallized- dark cores within every white worm like stalactite is evident. So before the chalcedony this was a complex radiating cluster of green tourmaline crystals from robust sizes to the finest needles imaginable.

The condition is outstanding, as I say it is tough and stable so will not suffer damage during shipping nor handling. Some minor imperfections are visible, I guess all attachment related.
