Some fine gems of peridot, garnet and turquoise have been found.
Certain stones, notably the peridot (or chrysolite) and the hessonite (or cinnamon stone), have an oily luster.
True olivine (the peridot or the chrysolite of the trade) is of a fine leaf-green or bottle-green shade in the peridot.
The name is unfortunate as it is identical with the true name of the mineral which gives us peridot.
Peridot, and the brighter olivine or chrysolite, while of the same mineral species, do not seem to occur together.
