Libethenite almost always takes the form of dark-green orthorhombic crystals.45 It is often found in clusters with other libethenite crystals.
Libethenite is found in the oxidized zone of copper ore deposits.6 It is most often formed from the weathering of phosphate rocks such as apatite, monazite, and xenotime.7 There have been no confirmed findings of primary libethenite, although a probable case has been reported.8
