MJ87G9: The sample, exceptional, is from a recent find in the now closed Jeffrey Quarry. The pocket, being big, produced very few specimens of such high quality. Diopside crystals have an uncommon habit: they are apparently tabular, but fine vertical striations and the presence of the pinacoid show they really are very flat prisms. The color and luster are excellent and the transparency extraordinary. If all this seems not enough, their association with prismatic greenish-yellow and violet Vesuvianite crystals adds even more interest and visual appeal to the sample.
