Malachite – Clara Mine, Oberwolfach, Freiburg, Germany
 Intense green malachite in a calcite matrix. The approximately 2 cm malachite sphere sits in a cavity covered with limonite and contrasts vividly, almost luminously, against the dark limonite.
 Since the malachite sphere is located in the cavity, it is absolutely flawless!
 In such quality, steps like these are an absolute rarity and are almost impossible to find on the market.
