Galena and Sphalerite with Quartz, Borieva Mine, Madan District, Southern Rhodope Mountains, Bulgaria, Mined 2014, Large Cabinet 6.0 x 11.0 x 18.0 cm, $650. Online 3/9/15.
Galena and quartz are common species from Madan but not in this configuration. In all the years I've been active in Bulgaria (since 1995) I have not seen a finer specimen like this of cubo-octahedral galena crystals on quartz. It is really a superior piece in terms of aesthetics, quality and form. Completely crystallized to all sides and in pristine condition. Mined 2014.
