TitleQuartz (youngite)
DescriptionYoungite is a name applied to a rock composed of mottled pink, white and gray drusy quartz and agate. It is often polished to make showy pieces or jewelry. The most notable source is in the Hartville uplift in eastern Wyoming. Youngite is a fluorescent rock and so can be found in black light displays at many museums. Although specimens are still for sale, the Wyoming location is now closed. This specimen is 24 cm across.
