youngite - quartz - silicon dioxide - brecciated - jasper

Youngite is an agatized brecciated jasper with a grayish translucent druzy quartz usually around the outer part of the material. The drusy quartz usually fluoresces green. The jasper center varies in color from a light tan, to a pretty peach, brown, reddish, salmon and variations of these colors. The material is very hard and is used in making gemstones such as beads and cabochons. Rare. Youngite is a variety of quartz. Silicon dioxide. Hardness 7.

The jasper center of this material is called brecciated due to its angular fragmentation. It is believed that due to a volcanic clastic shock the inner material became fragmented or broken into angular pieces and then silica/quartz cemented the fragmented pieces together.
