Lepidolite mica mineral specimens which are members of the mica group of minerals, specimens tend to have a lilac colouration, however, grey and rose are also colours which the mineral can be found in. It is often found in granitic rocks such as pegmatites as well as quartz veins, greisens and granites in general, where high temperatures are present. It’s lilac purple colouration have resulted in it being sought after as a gemstone in modern times, however, it is chemicallly important for modern technology as it is a secondary source of lithium, which is the main element present in almost all rechargeable batteries today such as phone batteries, tablets, controllers and more. It is also a major sources of the rare alkaline metals caesium and rubidium which are respectively used in various electrical components, accurate clocks, oil drilling, fireworks and more.
These particular mineral specimens of lepidolite mica exhibit a botryoidal crystal habit, in which the fine crystals have grown to appear as a ‘bubbling’ mass. The surface is smooth and is purple in colour. They come from Minas Gerais, Brazil and each specimen will be supplied in a card tray with an information label.

Cleavelandite is a variety of the mineral albite, one of the constituent minerals of plagioclase feldspar, thus is found in areas where pegmatites and granites exists in certain localities around the world. These particular specimens come from Evje, in Southern Norway and as expected, has a pale green colouration to it. As with albite, cleavelandite also exhibits a triclinic crystal habit and has a hardness of 6- 7 on the Moh’s scale of hardness, it is usually found within cavities of other rocks or minerals. It as named in 1823 by Henry J. Brooke in honor of Parker Cleaveland , professor of geology and mineralogy at Bowdoin College in Maine. Our mineral specimens are massive in form with occasional accessory such as smokey quartz or plagioclase or orthoclase feldspar.
