WOW! This is a MAJOR crystal of a very rare species, from an important and completely defunct locality! Krohnkite usually occurs as small crystals, or as lamellar aggregates filling fissure seams. Freestanding crystals are rare and those of several cm are already major for the species. This one is a whopping 8.5 CENTIMETERS! The crystal is fully formed though with some irregular growth on the edges, and is also fully terminated (slight etching but the termination IS obvious and distinct). It is completely translucent and even transparent in portions. The color is unreal - it LOOKS synthetic though it is most certainly not. Front and back views are shown (top and bottom panels, respectively). Old specimen with an antique Ward's label accompanying it. 8.5 x 2.2 x 0.9 cm
