A rare museum-sized, large display specimen of sharp zunyite crystals from a single find. This is truly an amazingly rich specimen of zunyite from the location which produced the world's best of species crystals! Vitreous, slightly translucent, sharply tetrahedral crystals 1mm on edge present as gray-blue crystals on the contrasting matrix. These are large, lustrous, exceptional crystals for the species from this well-known, yet unique occurrence from an erratic boulder in a farmer's field. One of the rarest finds of rarities! These zunyites come from a single pocket on a single boulder by a group of collectors hiking across a farm field nearly 40 years ago! Zunyite crystals are prolific on this piece! Specimens of any quality seldom turn up today of this species and this one features many small (1mm) to large (1.1cm), off-white to pale tan-gray, very sharp pseudo-pyramidal crystals richly distributed over the surface. A foliated "talc"-quartz matrix is host to these fine crystals. Discovered in an erratic boulder, literally sitting in a farm field, by mineral dealers Jim and Mary Walker in the early 80s as they hiked to another locality (this piece came from Jim Walker, and I obtained it and sold it first in the late 1990s!) This single productive boulder has not been traced to its origins in the nearby mountains, or duplicated in 30 years since. These numerous, sharp, interesting crystals are truly a treasure for the serious collector.
