Youngite

Earlier this week I acquired a nice piece of Youngite which is about 18 cm long. It is beautiful both under normal light and also under the shortwave ultraviolet lamp.

Wikipedia says: Youngite is an agatized breccia mineral from an area near Hartville, Wyoming.

This composite stone has a breciated Jasper center overlaid with a grayish translucent druzy quartz. It often looks some what like fuzzy brains and usually fluoresces green. The jasper center is lacy and ranges in color from a light tan to a very pretty peach or salmon color. This deposit is basically dug out. Youngite is sometimes polished into cabochons for jewelry or other decorative shapes.
