BLUE AGATE and BLACK AGATE WITH BLUE INTERIOR by Jan Baumeister
Chalcedony is a catch all term that includes many well known varieties of cryptocrystalline quartz gemstones. They are found in all
50 States, in many colors and color combinations, and in sedimentary, igneous, and metamorphic rocks. Chalcedony includes
carnelian, sard, plasma, bloodstone, onyx, sardonyx, chrysoprase, thundereggs, and agate, just to name a few of the better known
varieties. Because of its abundance, durability, and beauty, the earliest recorded use of chalcedony, in which agate is a variety, was
many thousands of years ago used for projectile points, knives, tools, and containers such as cups and bowls. Now days, it is hunted,
treasured as show pieces and put in jewelry.
Nebraska designated blue chalcedony (commonly called blue agate) as the official state gemstone in 1967. Blue chalcedony is a pale
stone which sometimes has a dark internal form with bands of blue and white and often has a colorless streak. Blue agate is found in
northwestern Nebraska, where it formed in wind-blown silt and clay stone deposited in the Chadron Formation of the Oligocene Age
New Mexico is famous for its Luna blue agate, mainly a light to medium blue color with some having both blue with black in them.
The Apache –Sitgrave National Forest hosts different kinds of blue as well as black and white agates, most with bandings. Golden
Luna agate has been found, also gold with some with red and white stripes. Several people from Rapid City, including myself have
happily hunted these beautiful agates as well as hunks of crystals, and enjoying free parking in two area campgrounds.
Wyoming has a couple areas of black agate with different shades of blue with white in the center found by the author. The locations
are not yet published. One area has beautiful material that has the beautiful "iris" prisms in it when cut thin and the agate looks so
much like the Balmorhia Blue found in Western Texas.
South Dakota - One area has of exposed black agate, some having nodules have limited blue and white bands inside. The white will
fluorescence lime green. The highly prized black agate is exposed in a very small area in the lower layers that make up the Badland
buttes.

California -- California's "Mojave Blue" agate has gained a great deal of attention in the past several years. This pastel blue or blue-
gray agate cuts into attractive cabochons for jewelry and, in the hands of an expert carver, makes outstanding carvings.
Florida--The famous silicified coral, first found in the Tampa Bay area around 1825 is the only gemstone of note from the State. The
coral is replaced by a waxy, translucent, botryoidal, or varicolored chalcedony. The material can be blue, red, brown, amber, white,
black, or a combination of these colors. The author has a very large flat piece of blue Florida agatized coral.
Oregon: The blue agate from Kittitas County, known as "Ellensburg Blue", is highly prized by local lapidaries. This incredible blue to purple seam agate is one of the most popular agates in the western Oregon area. There are also a few known and probably more undiscovered deposits of Holley Blue on the Calapooia River. The Holley Mt. area is the main area for this famous lapidary material. It is located on leased timberland. Bulldozed over and replanted, it was closed to digging as of spring 1997. There are other agate fields in the nearby area. References:
