- Baryte, Calcite
- Small Cabinet, 6.4 x 6.2 x 3.5 cm
- Sterling Mine, Stoneham, Weld Co., Colorado, USA
An old-time, fine specimen of classic, light blue baryte prisms on sugary calcite from the Sterling Mine of Colorado. The water-clear, windowpane with nice beveled edges measures 1.7 x 1.4 cm. The large baryte crystal cluster is contacted. Baryte has been known from this classic Colorado locale since the 1870s and this specimen definitely predates major collecting efforts in the 1980s. Ex. Mullane Collection and probably dates from the 1950s to early 1970s. Very highly representative of the locality and rare for the era of collecting.
