Sphalerite on Dolomite (classic locale) Soregaroli Coll.

Item Description

Lustrous, intergrown, black sphalerite crystals with flashes of rubyjack color flanked by complimentary fields of curved, saddle-shaped dolomite rhombs form an impressive large combination specimen from this historic mine in the Kansas portion of the famous Tri-State District. The dramatic large compound crystal at the top is 7.8 cm. The noted periphery wear on the left side of the piece is certainly only a minimal detraction to this excellent old combination classic from the Art Soregaroli Collection. Good timing with the current Mineralogical Record Special Issue of the Tri-State District just coming out.
