- Miniature, 3.4 x 3.2 x 2.1 cm
- Cromford, Matlock, Derbyshire, England, UK
TYPE LOCALITY 1851, for the species....this is a superb, sharp, 9 mm matlockite crystal in matrix of galena. Matlockite is exceptionally rare, especially in nice fat crystals such as this. While on close examination it has a contact on one corner, it is still impressive visually, and for the size and color.
