The chemical formula of mineral Aktashite is indicated by Cu6Hg3As4S12. Aktashite is usually found in hydrothermal deposits. Aktashite is commonly found at Gal-Kyaya deposits, Yakutia, and Aktash deposit, Altai Mountain, Russia. The mineral was named after its type of locality. Aktashite is known to crystallize in the trigonal system of crytal formation.

            Mineral Aktashite has no cleavage even if it is evaluated with the aid of polarized microscopes for mineralogists. Aktashite is most commonly found grayish black in color. It is most commonly found exhibiting nice and interesting microscope images under polarzing microscopes used in optical mineralogy. The specific gravity measure of the mineral is most commonly found 5.5 grams per cubic centimeters. Most crystals of mineral Aktashite are found opaque in appearance. Mineral Aktashite is usually found showing conchoidal to uneven fracture when viewed with the aid of petrographic polarizing microscope used in the field of optical mineralogy. Uneven fracture is usually found producing small, conchoidal fragments when viewed under polarized micorscopes for optical mineralogy. The crystal habits of the mineral as described in the field of optical mineralogy usually include anhedral grains that appear as granular minerals without the expression of crystal shapes. It can be also found as euhedral crystal occuring as well-formed crystals showing good external form when viewed with the aid of polarizing microscope used in the field of optical mineralogy. Aktashite can be also found with microscopic crystals that can be only seen more clearly visible when viewed with the aid of polarizing microscope used in the field of optical mineralogy. The hardness measure of the mineral Aktashite when it is evaluated using the Mohs scale method is usually found 3.5. Aktashite is most commonly found showing metallic luster when viewed in reflected light of polarized microscopes for mineralogists. Aktashite is most commonly found leaving a black streak when specimen sample is rubbed on a white porcelain streak plate. Aktashite is usually found showing weak anisotrophism in shades of blue. The interference color exhibited by Aktashite under polarized microscope is usually found white. Aktashite is a non-radioactive mineral as evaluated.
