Sphalerite and Quartz    Madan Ore Field, Rhodope Mountains, Smolyan Oblast, Bulgaria.  For a sphalerite from this prolific location this one is certainly exceptional.  It measures 8.2 x 5.5 x 3 cm overall with two distinct generations of translucent sphalerite.  There is one pin head sized micro ding that is not easily noticed so it isn’t “perfect”, but it is as close as it could be.  Fine luster and the aesthetics are impressive.  Excellent contrasts between specie’s forms and colors.  Displays great from any view.   $150
