This magnificent specimen is filthy rich in Edoylerite and they are "large", almost 1mm in some cases. There are two pockets of them on each end of the large vug. The greenish yellow areas are Edgarbaileyite, which is also very nice. Sprinkled about inside that large vug are scattered Edoylerite crystals. It is also rich in native Mercury and of course all the red is Cinnabar. Great specimen.
It will be sealed in a plastic container and be delivered by ground only because of the Mercury.

- pegmatite mineral
The late Art Smith acquired this specimen from David Seaman in the 1980's (see prov. tab). It is a nice representative specimen from this zoned pegmatite of "rubellite" elbaite tourmaline in colorless Pollucite. Mount Mica pegmatite can be classified as a poorly zoned Lithium-Cesium-Tantalum pegmatite. It was one of Maine's first gem mines and is a serial producer of gem quality tourmaline.
