Greenish gray or bluish green in color, its luster is metallic. Ardaite occurs as 50&nbsp;μm fine-grained aggregates of acicular crystals associated with galena, pyrostilpnite, anglesite, nadorite, and chlorine-bearing robinsonite and semseyite, in the Madjarovo polymetallic ore deposit in Bulgaria. Ardaite has a hardness of 2.5 to 3 on Mohs scale and a density of approximately 6.44.<ref name=mindat />

The type locality is the Madjarovo polymetallic ore deposit in the Rhodope Mountains.<ref name=NMNH>{{cite web |url= http://www.nmnhs.com/exhibitions-hall-1-mineralogy-en.html |title=Collection of Minerals |publisher= National Natural History Museum, Sofia, Bulgaria}}</ref><ref name=Madjarovo>{{cite web |url= http://www.mindat.org/loc-460.html |title= Madjarovo deposit |publisher= mindat.com}}</ref> Later its occurrence was proved in the Gruvåsen deposit, near Filipstad, Bergslagen, Sweden.<ref name=Second /> {{clear left}}
