Calcite on Dolomite    Hanson Quarry, St. Johnsville, New York.  Ex. James Cranston collection.  A fine miniature which sports a large parallel growth group of translucent to transparent crystals of the typical yellow color for the locale.  They have moderate to heavy inclusions of marcasite on the backside.  All views are good so backside may be a poor way of saying this as any side displays so well.  Minor edge and base contact which is expected and all display faces are clean.  4.6 x 3 x 3 cm.  Great luster and a fine specimen.   90$
