Calcite

A characteristic Calcite miniature from Millclose mine at Wensley, South Darley in Derbyshire, England, approximately 4 km north-west of the town of Matlock.  The double terminated crystals of gemmy to translucent Calcite measure up to 3.5 cm and emerge from a mixed crystallised to granular Calcite-Sphalerite matrix.  Several of the Calcite crystals are also twinned.  All have a bright, glassy, reflective lustre and show typical colouring for Derbyshire Calcite, grading from colourless and milky to pale golden tan, the latter is subtle in this specimen.  It’s a lovely example of Calcite from this most famous and important of Derbyshire localities.
