Vanadinite on Calcite

125 x 67 x 51 mm overall
up to 6 mm Vanadinites

Hundreds of yellow, somewhat hoppered Vanadinite crystals to 6 mm cover clear crystals of Calcite, and are themselves partly coated by Calcite. Unlike the typical reddish crystals from this small mine, last mined in 1952, these yellow Vanadinites are rare and unusual. This is old material, seldom seen on the market, particularly in this large of a specimen. I can only find three broken crystals on this richly-covered specimen.
