5.4" Polished Wyoming Youngite Agate/Jasper Slab - Fluorescent

This is a 5.4" wide polished slab of Youngite that was collected from the Youngite Caves near Guernsey in Platte County, Wyoming. Youngite is a brecciated jasper that is often found encrusted in chalcedony. Under short wave UV, this agate fluoresces vibrant green.

The term "brecciated" is related to a previously solid rock that has undergone pressures and shifting that caused broken-up, angular fragments. Following the breaking of this rock, ground water containing silica assisted in the natural cementing process of the fragmented rock, resulting in this beautiful mineral formation.
