Isolated, pseudocubic, crystals of lustrous and translucent, butterscotch-colored, wulfenite, to.9 cm in length, color contrast nicely with a few sharp disc-shaped (rhomdohedral) crystals of, lustrous, white calcite, to .75 cm across. All of these crystals are emplaced on contrasting deep brown limonite for stunning contrast. This piece may have the best calcites of hte pocket, from what I see...they are brilliantly white, almost pearlescent and silky in luster. It is very interesting, as a Mapimi specimen...but also just for the elegant contrasts in and of themselves.
