Stichtite
Stichtite was discovered in 1910 in Dundas, Tasmania, Australia. It was named after Robert Carl Sticht the manager of the nearby Mt Lyell copper mine.
Stichtite is purplish pink to purplish rose-red in colour and it is often associated with a chromite and green
serpentine. This combination makes interesting specimens and attractive ornamental stone for carvings.
