Day #14 Deskcrop: Unakite Pebble

Today’s small deskcrop comes from the shores of Batchewana Bay in Ontario, Canada. It’s a very well rounded pebble of epidote (probably of vein origin) with a little orange cap of granite. This rock’s beautifully contrasting palette is what makes unakite prized as a semi-pecious gemstone – I just picked it up because it was pretty. The rounding results from mechanical abrasion in the surf zone along a pebbly beach on the eastern shore of Lake Superior.
