{"product_id":"calcite-15","title":"CALCITE","description":"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 as what are known as 'macles'.  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.
