It crystallizes in the monoclinic system and has a dark, metallic luster, a specific gravity of 6.285 and a Mohs hardness of 5.5.[2]

Achalaite occurs in the intermediate zone of topaz- and tantalite-bearing pegmatite.[2] Associated minerals include rutile, quartz and albite.[3]

Its name comes from the type locality: the Achala batholith in Córdoba, Argentina and the mineral has been approved by the IMA with the acronym 2013-103.[3]
