This specimen features lilac-colored, foliated stichtite intergrown with green foliated serpentine. The note "may contain barbertonite in admixture" refers to the possibility of a closely related mineral being present. This particular piece was acquired by Dr. Tarassoff in 1975 through an exchange with W. Birch, Curator of Minerals at the National Museum of Victoria.
Stichtite is a rare, hydrated chromium magnesium carbonate that forms as an alteration product of chromium-bearing serpentine. It was first discovered in 1910 in Western Tasmania, Australia, and was initially recognized by A.S. Wesley, the former chief chemist of the Mount Lyell Mining and Railway Company. The mineral was named in honour of Robert Carl Sticht, the mine manager at the time. Specimens of stichtite are highly sought after due to their vibrant colour.
