A sample consisting mostly of rough, pale greenish-white needles of crystallized jadeite with well-defined, radiating sprays of indigo glaucophane to 8mm. Previously in the collection of (and presumably collected by) Ed Oyler, with his handwritten note on a slip of paper; he notes the jadeite crystals are "not beautiful, but very rare."

4.0 x 3.2 x 3.0 cm

Note that there are several localities around the Valley Ford area listed in MinDat, but I have been unable to narrow it down to anything more specific.
