Physical properties

Hardness of 6.5 to 7 on the Mohs scale. Displays earthy tones of red, yellow, pink, and white with a waxy to vitreous luster.

Formed from the accumulation of microscopic skeletal remains of radiolaria in marine environments millions of years ago.

Primarily used for lapidary work, cabochons, carved decorative objects, and jewelry making.

Mookite is an Australian jasper exclusively sourced from the Mooka Creek station in Western Australia.

Identified by its distinctive multi-colored pastel and earthy patterns; highly sought after by lapidary collectors.
