A stellar, natural top blue without any enhancement. The color of tanzanite is fantastic, in fact remarkable for the epidote group. To see through its prism, a lighter shade of windex blue is beneficial to transmit light and this one is just right.

- Leonard Mine, Butte District, Silver Bow Co., Montana
- Overall Size: 2.7 x 2.7 cm
This is an unusually fine and superb display of metallic, blue-black covellite crystals. They are bright, iridescent crystals in absolutely pristine condition. They are also nicely exposed and well separated for a vein filling sulfide. This piece was likely extracted during the 1970’s, and eventually ended up in the collection of Al McGuinness, accompanied by his label and a bit of interesting history. If tilted slightly it measures 3.3 cm without damage.
