hessonite

Hessonite is rather a soft stone, its hardness being about that of quartz or 7, whilst the hardness of most garnet reaches 7.5.

Certain stones, notably the peridot (or chrysolite) and the hessonite (or cinnamon stone), have an oily luster.

Brown garnet (hessonite or cinnamon stone), sometimes wrongly called hyacinth in the trade, is of a deep reddish-brown color.

The hessonite garnets are frequently brownish red and are sometimes called "cinnamon stones."

Hessonite garnet furnishes yellowish-red and brownish-red stones, which are sometimes also called "cinnamon stones."
