A double terminated Quartz crystal with smaller sub crystals which are included with dark green colored Tourmaline. Many of Tourmaline crystals are not completely included and extend out of the Quartz and a few are terminated. The Quartz has a slight gray color and is relatively transparent, so the Tourmaline crystals are readily visible within the Quartz. The color of the Tourmaline varies due to the thickness of the crystals with the thickest one appearing black. One of the Tourmaline crystals is hollow. Also, there are two sections of larger crystals which are just thin, hollow shells, the inner surface of which is composed of fibrous subcrystals which produces a chatoyant effect (there may be some pseudomorphing present here). Next to and partially on the surface of one of these is a round halo like shape composed of a druze of very small, unidentified, fibrous crystals which are off white in color.

Condition: Fairly Good

Flaws: Two of the Tourmaline crystals are not terminated. There is some bruising on some of the edges of the Quartz crystals and there internal fractures in the Quartz crystals.
