Hemimorphite (Calamine)

Item Description

An extremely old, 19th. Century specimen, this matrix specimen features a crust of lustrous, interlocked crystals of white to tan crystals of hemimorphite. Calamine is the pre-1900 name for the mineral hemimorphite. This old specimen is from the William Jefferis collection at Carnegie. Jefferis was one of America's greatest mineral collectors of the 19th. century and his collection formed a huge core to this museum. Overall a fine specimen anyways, with sparkling, brilliantly lustrous crystals covering matrix and dating to the mid to late 1800s. This is one half of an original specimen with one label, that split somehow in the past. It is identical in quality to the previous piece but comes with a color copy of the label which remains with the slightly larger portion....a good value for the piece, probably, if you do not wish to pay extra for the historic label as well.
