Valentinite with Sphalerite, Galena and Quartz

Although the wonderful label accompanying this large miniature proves it is from an old collection, its appearance undoubtedly confirms this. It is strange how such old-time pieces from pre-twentieth century collections have a certain look, but they so often do. A Galena matrix tarnished with age to a dark sooty grey patina is overgrown by Sphalerite and Quartz crystals, plus an approximately 2.5 x 1 cm coverage of cream laths of crystallised Valentinite with a silky lustre. Valentinite is an antimony oxide. The base of the specimen is coated with 1 mm Sphalerite crystals varying from opaque black to semi-transparent burnt tangerine and claret red. The antiquarian label is written in Italian (I think) and perfectly complements this lovely specimen.
