AA lustrous deep blue Quartz colored from the inclusions of Shattuckite, the rare copper silicate. 

A beautiful and striking cabinet specimen of Shattuckite, a rare copper silicate, and associated deep green primary Malachite and Quartz.  A vug of velvety large spheres of acicular crystals of royal blue Shattuckite.  Much of the vug is filled with deep green primary Malachite.  There are also the lighter blue reverse concave side of the velvety spheres which are opposite the dark blue velvety mounds of acicular crystals. Displays splendidly horizontal or vertical. 

An exceptional and aesthetic miniature specimen that could be trimmed into a thumbnail.  A vug of velvety spheres of acicular crystals of royal blue Shattuckite.  The backside also has associated green Malachite. 

A beautiful and striking cabinet specimen of Shattuckite, a rare copper silicate.  A large vug of velvety large spheres of acicular crystals of royal blue Shattuckite.  The dimensions of the vug's opening is 5 x 2 x 2 cm.  Displays in several positions as seen in the photos.

A solid crust of Shattuckite, a rare copper silicate, with minor green Malachite on the outside.  Inside a vug of velvety spheres of acicular crystals of Shattuckite.  These velvety spherical acicular cyystals seem to have a whitish thin coating of something.  I do not know is this is removable or another rare mineral.   You can see it in the photos.  It does detract  from the beauty of the velvety dark blue Shattuckite.  I just saw some of the white material on another specimens Malachite and it looks like it is just fine dust.  When I get a chance I will try just blowing it off with compressed air.  I blew on it a little and the white did not come off.  I do not know what it is.  Most have a little.  This one has more and so the price is adjusted much lower.
