rocks, minerals, gemstones
The ROCKS AND MINERALS listed below are specialty items such as ulexite and Moqui marbles.

ULEXITE ("TV ROCK") is a mineral of borax whose structure is parallel making it a natural "fiber optic" transmitter. As a result, when you place a piece of ulexite over a written page, the letters and words will be "lifted" or "projected" to the surface of the rock and appear much like a picture on a TV screen.
While there are several grades of ulexite available on the market, we currently offer GRADE A material because of its clarity. Our specimens are irregular in size and shape. Specimen measurements are commonly based on the length of the longest side of the piece. The accompanying photo illustrates the variation.

Ulexite comes in different grades: The small and medium samples are Grade "A". These specimens are clear with only an occasional inclusion. Small pieces are approximately 1.0" - 1.25" and medium pieces are approximately 1.5" in size.

The large samples are average grade. All specimens are clear enough to see through with inclusion. Large pieces are approximately 3.0" in size.

MOQUI MARBLES Some of the best areas for collecting Moqui Marbles have been closed to collecting since they were included in a new National Monument. Consequently, supplies of these unique geological specimens are becoming relatively scarce. Fortunately, we were able to purchase several pounds of legally acquired Moquis. Once these are gone we may not be able to get more. If you have been thinking about buying a Moqui, now is a good time.

Small Moqui Marbles - These unique "marbles" were formed millions of years ago when a nucleus of sand was coated by a layer of hematite. These dark gray/black marbles are approximately 0.75" in diameter. Shapes vary from round to elliptical.
Medium Moqui Marbles - Same as above but approximately 1.0" in diameter.
Large Moqui Marbles - Same as above but approximately 1.5" in diameter.

Apache Tears in Perlite Matrix - Apache tears are an opaque form of obsidian with a legend behind them.

During a battle between the U.S. Cavalry and a small band of Apaches on a mountain near Superior, AZ, the Indians found themselves trapped on the edge of a sheer precipice several hundred feet high. Faced with defeat and capture at the hands of their enemies or death, they chose the latter and leaped from the cliff, dying on the rocks below. The great spirit looked down on their grieving loved ones and turned their tears into opaque, black stones so that all who see the stones will remember the lost warriors.

Apache tears are also considered to be good luck stones containing extremely potent protective energies and are believed by some to be helpful in promoting peace and good for grounding and centering.

Apache Tears - No matrix - These tears are larger specimens than the SM-065c above and come from the same deposit but are NOT in a perlite matrix.

Fulgurite - The name for these natural rarities - Fulgurite - is derived from the Latin fulgur meaning "lightning". They are the result of lightning striking the Earth's surface melting the soil, sand or rock where the right combination of soil composition, strike intensity and strike duration occur. Fulgurites are often hollow. This void is created by the expansion and escape of gas and moisture that result from the explosive fusion during the strike.

We offer three different types of fulgurites:
  • S450 - Smooth texture from the eastern plains of Colorado
  • S451 - Sand texture from the Florida beaches
  • S452 - Rocky texture from Boulder Canyon in Colorado

Native Copper - These specimens of native copper (shown on the right in the photo) are "hackley" (having sharp, jagged edges) and have inclusions. They are from the Caledonia Mine in Ontonagon, Michigan. Available in two sizes:
  • SM200b - Small is 1" to 1.25".
  • SM200c - Medium is 1.5" to 2".

Copper Nuggets - These beautiful, naturally occurring copper nuggets (shown on the left in the photo) are tumbled specimens with a few inclusions. They come from the Keweenaw Peninsula in Michigan. Available in two sizes:
  • SM201b - Small is 1" to 1.25".
  • SM201c - Medium is 1.5" to 2".

Purpurite (Heterosite) - [(Mn, Fe) PO4] is the manganese and iron end-member of a beautiful and rare phosphate. It occurs as massive purple and rose colored pieces, which is the result of time and alteration from primary phosphates originally crystallized in a granitic pegmatite.
These specimens also contain other phosphates, as well as feldspar, mica or quartz as accents. Specimens are from the Crystal Mountain District, Larimer County, Colorado.

Available in two sizes:
  • S455B - Small is 1" to 1.25".
  • S455C - Medium is 1.5" to 2".

Carborundum Crystal - Carborundum is a beautiful decorative rock displaying a wide spectrum of colors from dark violet to light blue/azure, brown, red to orange and yellow.
It forms as a result of the synthesis of quartz sand (SiO2) and carbon (C) in the absence of oxygen at the high temperature of 2,200 degrees Celsius. Under these conditions quartz is transformed into a gaseous phase and penetrates the insoluble carbon. This reaction results in the crystallization of a very hard rock (9 in Mohs scale), resistant to chemical and mechanical agents.
Carborundum is used in industry for the manufacture of cutting and abrasive materials. Specimen is about 2" in size.


Petrified Wood with Quartz Crystals - Interesting and unique specimens. Petrified wood is actually considered to be a fossil. The organic matter in the original tree was completely replaced by minerals. This type of fossilization is known as permineralization. The term, "to petrify", literally means, "turn to stone." Petrified wood, then, is wood that has turned to stone. These specimens have a crystalized core of tiny quartz crystals. Available in two sizes:
  • S335 - Small is 1" to 1.25".
  • S336 - Medium is 1.5" to 2".

Zebra Marble - Zebra Marble comes from Utah, and as the name implies, is a combination of black and white stripes. This rock is 3 to 5-1/2 on Moh's hardness scale, making it an excellent choice for carving, knapping, and cutting. Specimen is approximately 1.5" to 2.0" in size.
$ 3.00 ea.

Lodestone - Specimen shown is covered with iron filings to illustrate the magnetism. Not just "magnetic" like some minerals but a true magnet with definite polarity. The only true magnet in nature. Available in two sizes:
  • S410b - Small is 1" to 1.25".
  • S410c - Medium is 1.5" to 2".
These are great specimens.

Pipestone - Pipestone (Catlinite) is the sacred red clay stone that American Indians use for making prayer and ceremonial pipes. Our pipestone is of excellent quality. We price our pipestone by the piece and try to offer a nice assortment to better suit your specific need. See Pipestone page for available piece sizes and prices plus history and geological information about the famous, historical Minnesota deposit. If you need additional information, please e-mail or call us.
Steatite - In its natural state, Steatite is a gray colored metamorphic rock composed primarily of the mineral talc. It is very soft and can be carved and transformed into a beautiful, lustrous, deep black colored pipe or effigy. For the experienced stone carver, it provides a beautiful contrast to the traditional red pipestone. See Steatite page for available piece sizes and prices. If you need additional information, please e-mail or call us.
