Aside from Kentucky’s enormous coal deposits, the state also has Kentucky agates, chert, concretions, flint, fluorite, galena, geodes, and fossils.

Can you find gemstones in Kentucky?
There are quite a couple of gemstones that you can find in Kentucky, such as freshwater pearls, Kentucky agates (in the regions mentioned above), amethyst, malachite, or chalcedony, among others.
What crystals can be found naturally in Kentucky?
Most often, geodes found in Kentucky are lined with quartz crystals. Less commonly, the calcite or dolomite crystals are found on the inside, either alone or associated with bitumen, barite, galena, fluorite, quartz, limonite, sphalerite, pyrite, selenite, or celestite.
Can diamonds be found in KY?
Kentucky contains both of these type of rocks — kimberlites in Elliott County and lamprophyre dikes in western Kentucky — although no naturally occurring diamonds have ever been found in either of these rocks.
What valuable minerals are found in Kentucky?
Fluorspar, galena, sphalerite, barite, iron, and phosphates are all minerals that were once mined in the state, but mining them is currently uneconomical; however, Kentucky has many resources and reserves of fluorite and zinc, and these commodities may be mined in the future.
Where can I find geodes in Kentucky?
The best place to find geodes in Kentucky is the Blue Grass region, south of Lexington. In general, geodes can be found in stream beds and gravels near outcrops of the Warsaw and Fort Wayne formations in the central part of the state, especially in Lincoln, Adair, Jefferson, and Lyon Counties.
Is there gold in Kentucky?
Kentucky does not have the geological conditions that you would hope for when prospecting for gold. There is no naturally occurring gold within the state. And unlike many of the Midwestern states, Kentucky was too far south to get any appreciable amount of placer gold deposited by glaciers from Canada.
What is Kentucky agate?
Kentucky agate is a beautiful mineral found in east-central Kentucky, first discovered in the 1970s, and a collector’s item. It is composed of chalcedony, a microcrystalline form of quartz, and has delicate and varying shades of colors arranged in various patterns in quartz nodules and geodes.
What do raw geodes look like?
What you’ll typically find on a geode is a bumpy, uneven surface. Sometimes you can even find them with nodule like bumps on the outside surface. If it’s smooth, then most likely what you have is not a geode. Geodes are almost always spherical in shape, meaning they will almost always be round.
Are geodes worth money?
According to Answers.com, the value of a geode “…Baseball sized geodes with non-spectacular quartz or calcite crystals can be purchased for $4-$12. Geodes with uncommon minerals that are sold on mineral auction sites range in price from $30-$500. Golf ball sized geodes, uncracked, are sold for about $2 at shows.”
Is there Silver in Kentucky?
The legend of the Jonathon Swift Silver Mines is well known in Kentucky.It is very unlikely that there is any natural occurrence of gold, silver, or any precious metals in the Paleozoic rocks of eastern Kentucky.
Where is gold found in Kentucky?
Kentucky Gold Locations
Gold is found in small quantities in several places in the northern parts of the state particularly in Kenton, Campbell and Boone counties. Records show that placer gold deposits have been found in areas along the Ohio River, although the quantities of gold in the places were quite limited.
What kind of stone is in Kentucky?
The official state rock of Kentucky is agate, which is a specific variety of quartz geode.
What are the black rocks in KY?
In Kentucky, a dark-colored igneous rock, peridotite, occurs in sills and dikes (intrusions) in Elliott County in eastern Kentucky and Caldwell, Crittenden, and Livingston Counties in western Kentucky.
How do you find geodes?
There are many spots where geodes are more commonly found, such as riverbeds, limestone areas, or volcanic ash beds of deserts. Explore these natural spots for a better chance of finding a geode. Limestone is typically found in warm, shallow water areas and is usually a shade of tan or bluish gray.
Where can you find agates in Kentucky?
Beautiful specimens of red, black, yellow, and gray banded agate have been discovered in Estill, Jackson, Powell, Madison, and Rockcastle Counties. These Kentucky agates are derived from the Borden Formation of Early Mississippian age and can be collected along some rivers where the Borden is exposed to weathering.
Are agates rocks?
Agate (/ˈæɡ.ət/) is a common rock formation, consisting of chalcedony and quartz as its primary components, with a wide variety of colors. Its IMA symbol is Aga. Agates are primarily formed within volcanic and metamorphic rocks.
What kind of rocks are geodes?
Sedimentary Geodes
Geodes in sedimentary rocks are usually found in limestones, dolomites, and calcareous shale. In these deposits a gas-filled void can serve as the opening for geode formation.
What is mined in Kentucky?
The production of minerals and fuels in Kentucky is a multibillion dollar industry. Historically, coal, oil, natural gas, limestone, sand and gravel, clay, fluorite, barite, lead, iron, phosphate, zinc, and brines have been produced in the state.
Were there glaciers in Kentucky?
Glacial drift in north-central Kentucky, and glacial erratics scattered over much of the northern and western parts of the State (Leverett, 1929, fig. 3), indicate the presence of glacial ice during the Illinoian and older stages.
Is there any precious metals in Kentucky?
Minerals are an important part of Kentucky’s economy (Table 1). Kentucky is the only state to have an active fluorite mine; it is located in western Kentucky, which was once a large mining district.Metallic minerals are not being mined in Kentucky at the present time, but they have been in the past.
