Named for the bright green fluorite found within, the Emerald Ridge Pegmatite is a former artisinal fluorite mine located in the Katemcy Granite Batholith, beneath rolling ranchland north of Mason, Texas. Most of the gem bearing pegmatite is unexcavated. The pegmatite itself is composed of miarolytic granite studded with pockets of beautiful fluorescent emerald-green fluorite, both in massive form and as facet-grade octahedra to 4 cm. Screening the pit gravel will uncover the occasional light blue or water clear euhedral topaz crystal.
100 meters east of the pegmatite is another containing many small 1-5 cm terminated quartz points, many colored pink, red or orange with inclusions of hematite. Occasionally these are iridescent. Known locally as "strawberry quartz", the crystals occur singly or in beautiful clusters and plates. Beautiful zoned purple amethyst has been found here as well. This pegmatite also contains many perfect 3-6 cm crystals of pink microcline weathered from the granite.
The site is located in rolling ranch land with no undue hazards to collectors, other than the occasional prickly pear cactus, so the site is ideal for children. There are numerous large tailings piles loaded with quartz and fluorite of nearly every color, for them and others averse to hard rock mining.
