Where to find gemstones in ohio

The Native Americans used the flint for making spear points, arrowheads, knives and other ceremonial objects. The Vanport flint is generally found in light shades of yellow, red, green and few other colors.

Flint is a variety of quartz with impurities that give it the varied colors. Collectors often make colorful jewelry out of polished flints from Ohio, and flintknappers still make arrowheads with this material. Calcite Calcite is found in western and central parts of Ohio.

Calcite may be found in clear form and also in golden and dark brown colors. Allen County in northwestern Ohio has calcite and many other minerals and is an extremely popular site for rock collectors.

Celestite Celestite, or celestine as it is also known, is present in a few places in north western Ohio. The mineral is generally found as white or light blue crystals. It is a source of strontium and is widely used commercially in the making of fireworks and flares.

Many have a golden color. Celestite — Strontium sulfate. Northwestern Ohio produces crystals of this mineral in colors ranging from white to a beautiful pale blue.

Crystal cave on South Bass Island is a large vug filled with very large crystals of celestite. Diamonds — Carbon. At least six diamonds have been found in Ohio in sediments deposited by glaciers of the Pleistocene Ice Age. All were small crystals. As with gold, these minerals were carried to Ohio from Canada by glaciers. In recent years, diamond-bearing kimberlite pipes have been discovered in the Canadian shield and they may have been the source for rare Ohio diamonds.

Dolomite — Calcium magnesium carbonate. Interesting crystals, ranging in color from white to brown to pink, occur in northwestern Ohio in association with other minerals.

Flint — Silicon dioxide. Amorphous silica occurs in nodules or beds in Devonian limestone and particularly in Pennsylvanian limestone. It is thought that the silica was derived from the siliceous spicules of sponges. The most conspicuous bed of flint is associated with the Pennsylvanian-age Vanport limestone at Flint Ridge in Licking and Muskingum Counties.

Although most flint is gray or black in color, Flint Ridge flint is characterized by its light color with hues of red, green, yellow, and other colors. Flint was quarried by American Indian cultures for spear points, knives, scrappers, and other functional and ceremonial objects. Today, collectors polish Ohio flint into colorful jewelry. Fluorite — Calcium fluoride. The Findlay Arch mineral district produces interesting crystals of fluorite in brown and sometimes purple, green, and yellow, usually in association with calcite and other minerals common to the district.

Galena — Lead sulfide. This gray-colored heavy mineral is an ore of lead. Small cubic crystals of galena occur in the Findlay Arch mineral district. Gold — This native element occurs as small flakes and is found by panning gravel in the beds of modern streams. Gold was transported to Ohio by glaciers of the Pleistocene Ice Age and modern streams have eroded the glacial sediments and concentrated the gold particles.

Many streams in the glaciated portion of the state, or rivers draining the glaciated areas have produced small amounts of gold. It's located at Wiley Well in the north Imperial Valley. A: Ohio is not a hot spot for geodes. That doesn't mean you won't find any, but you don't have immediate go-to spots. Findlay Arch mineral district in northwestern Ohio has crystal geodes with minerals including calcite, celestite, dolomite and fluorite inside.

But it's hard to find natural outcrops in this glaciated area. Most geode finds have been in quarries that are not open to the public for collecting. Another place with geodes in Ohio is an area in the southern parts of the state in Adams and Highland counties. Called the Serpent Mound zinc district, it's home to some geodes containing calcite and barite. Crystal Cave in Ohio is called the world's largest geode. It was discovered over years ago and is located 40 feet below the earth's surface.

The geode cave is in places 35 feet in diameter and contains crystals weighing up to pounds. A: You'll need permission from a landowner to enter land owned by someone other than yourself and certainly to treasure hunt there. But no geode licenses or permits as such are required.
