Ajoite forms excellent microcrystal specimens. The small prismatic crystals are often arranged in tufts with an almost aquamarine-like blue green color. The color variety in a single multi-mineral specimen is sometimes surreal. Massive samples of ajoite are also unique and are sometimes carved or tumbled and can be used as an ornamental stone. Ajoite's classification as a phyllosilicate is questionable as its true structure is as yet unknown.
Color is blue-green to light green.
Luster is dull to vitreous. Transparency specimens are transparent to translucent. Crystal System is triclinic, bar 1. Growth Habits include acicular to thin prismatic crystals often found as spherules or sprays of acicular radial crystal clusters and as massive specimens. Cleavage is perfect.
