A superb competition level diaboleite specimen! Several impressive and lustrous, gorgeous blue, tabular crystals of diaboleite are attractively clustered on a matrix consisting of hydrocerussite, wherryite and leadhillite crystals and their granular aggregates. These stunning platy, tetragonal diaboleite crystals measure up to 1.5cm across which are very large for the species! They are attractively arranged as an exquisite royal blue grouping that accents the top of the hydrocerussite-wherryite-leadhillite matrix. An exceptional thumbnail/toenail specimen! Ex. William Pinch collection with label.
