Cacholong

The name of cacholong has a Kalmuk origin. Kalmuk agate is another name for the mineral. Sometimes plain folk also calls it ‘milk of sacred cows turned into stone’.

Actually, cacholong is not an individual stone but a variety of opal. It has a greenish, blue-greenish, swamp-green or green-brownish coloring. However, milk-white specimens with specks of other tints are the most common. It is an opaque stone; characterized with vitreous, pearly lustre.
