Where can I find gemstones in West Virginia?

a pink chalcedony, a silica mineral precipitated from water; found in the Mauch Chunk Group in Summers County.
a yellowish-green calcium-aluminum-iron silicate mineral, usually of metamorphic origin; occurs in veins of the Weverton Formation near Harpers Ferry in Jefferson County.
an amorphous (non-crystalline) silica that reflects light in a play of colors; occurs as small stalactites (cone-shaped deposits of minerals) on the underside of large sandstone overhangs, such as large cliffs of the Pottsville Sandstone near Coopers Rock in Monongalia County.
a hard, glassy crystalline silica mineral that may occur in a variety of colors including white, pink, and violet; when colorless and transparent, it is called "rock crystal"; found in the Oriskany Sandstone west of U.S. Route 522 north of Berkeley Springs in Morgan County.
a single occurrence in Peterstown, Monroe County, found by William "Punch" Jones in 1928; no additional diamonds have been found in West Virginia.
