System:MonoclinicColour:Black, gray in reflected ...
Hardness:2½ - 3
Name:Named in honor of Dr. Seved Djurle (1918– ), a Swedish chemist who first synthesized the synthetic equivalent (before the mineral was discovered).


A copper sulphide closely related to chalcocite.
Identification requires XRD methods.

Classification of Djurleite

IMA status:Approved
Explanation of status:The original paper describing the mineral used specimens from five different localities. The chemistry was determined on a specimen from the Copper Canyon, Mexico, while X-ray diffraction lines were calculated from a Butte, Montana specimen. The other specimens were also x-rayed.
