Beschreibung:

Silverton,Colorado The silver mines of Colorado and Peru both produced bright pink rhombohedral crystals of rhodochrosite. Although recent times have produced giant red crystals from both localities, the pink crystals on matrix are the classic examples from the 1960s and earlier. The large specimen has pink rhombs to ½ inch across, with light pink rims, intergrown with white quartz on a matrix of white quartz and dark silver ore. The bottom of the piece has been sawn, as is often the case for old specimens, measures 7 x 5 x 2 ½ in. The smaller specimen shows medium pink rhombs amid ½ inch clusters of fine quartz needles on a matrix of dark sparkling silver ore. It is probably from Colorado, but may be from Peru, measures 3 ½ x 2 x 1 ¾ in (2)
