Chester, Hampden Co.
4.19 x 3.37 x 1.52 x inches (10.66 x8.58 x 3.88 cm)
Also known as Empholite, Kayserite or Tanatarite, Diaspore is thankfully not very often called by one of these different names. It is, however, a rather unique and attractive mineral which is often faceted into quality gemstones. While not the official type locality for this mineral, material from the Chester Emery Mines in Hampden County, Massachusetts is clearly significant. This specimen sparkles a brilliant green, looking more like a Christmas ornament than a collectible mineral. The center of this layered piece has an array of large, flat, platy crystals which are quite tabular at the top edges. This lava-like slab is iridescent. PLEASE NOTE: WHILE THE LABEL PROVIDED WITH THE SPECIMEN INDICATES IT IS DIASPORE FROM CHESTER, MASSACHUSETTS, THIS PIECE IS LIKELY NOT A NATURAL MINERAL NOR DIASPORE. MANY PIECES ARE SOLD ON THE MARKET AS DIASPORE WHICH ARE MANMADE.
Estimate: $200 - up.
