This is one of those specimens for which you cannot really avoid shouting “Wow!”.  It’s a quite amazing large cabinet specimen of Quartz forming a superb Gwindel habit and whose surface is coated and shallowly embedded with highly lustrous Clinochlore crystals.  This large cabinet specimen is from Dodo mine in the Prepolar Ural, Western-Siberian Region, Russia.  It is a spectacular example of a Quartz Gwindel, in which the Quartz crystals have grown sideways and parallel to the c-axis, and are characteristically twisted, forming an overall curved surface.  Sometimes this curvature is not readily apparent in Gwindels, but there is no mistaking it in this specimen.  The Quartz crystals are, as far as I can determine through the coating of Clinochlore, colourless to smoky and transparent.  The longest measurable Quart crystal is 9 cm, but others are difficult to determine as they are intergrown and partly mask one another.   The dark green Clinochlore coats the Quartz crystals in vermiform stacked booklets of platy crystals which are so bright and lustrous, at first appear to be micro crystals of Pyrite.  The worm-like network of Clinochlore forms a finely meshed net over the entire specimen making all the surfaces appear sparkling dark green.  However, when held against the light, the transparency of the specimen transmits through, clearly defining where the mesh of interlinked Clinochlore crystals are positioned.  This is a magnificent Russian Quartz Gwindel coated with Clinochlore crystals, a specimen worthy of any top museum of natural history.
