The ROCKS, MINERALS & OTHER SPECIMENS listed below are specialty items such as Itacolumite (flexible sandstone), Ulexite (TV Rock), Moqui Marbles, Lepidolite with Rubellite, Rhyolite Wonderstone, Archean Butterstone, Moqui Marbles, Fluorescent Minerals, Carborundum, and Fulgurites. |
ITACOLUMITE is a porous rock that is a quartz-rich flexible sandstone. The porous, void spaces, enables the bending process that is apparently caused by the leaching of various mineral grains (possible feldspars and/or mica) creating an interlocking quartz grain matrix. The unique and rather amazing character of these 'bending rock' provide a great 'show & tell' for any rock enthusiast! Our specimens are from Stokes County, NC, though they are also found in Brazil and India.

Itacolumite - Flexible Sandstone - This rock is one of the world's stangest specimens - unique and rare! Our specimens from Stokes County, NC come in many shapes and sizes as indicated.
We also have some very large specimens (over 1.5 feet in length, up to 3 inch wide & about 1/4 - 1/2 inch thick), but these very rare and fragile specimens will take extra special care to ship and also are rather pricey. If interested, please contact us.

MOQUI MARBLES These unique "marbles" were formed millions of years ago when a nucleus of sand was coated by a layer of hematite. Some of the best areas for collecting Moqui Marbles have been closed to collecting since they were included in a new National Monument. Fortunately, we were able to purchase several pounds of legally acquired Moquis.

RI102 |
Rhyolite - Wonderstone - is a beautifully banded volcanic rock with a fine-grained texture (due to rapid cooling of the magma). The unique and varied coloration (maroons, dark pinks, light yellows) and decorative patterns in the stone are the result of circulating ground water that contained iron oxides. These specimens are from desert in Utah.

Ulexite - TV Rock Is a mineral of borax whose structure is parallel makiing it a natural 'fiber optic' transmitter. As a result when you place a piece of Ulexite over a written page, the image appears to be 'lifted' or projected onto the surface of the mineral, and appear much like a picture on a TV screen. Our Ulexite is Grade A, specimens are clear with occasional inclusion.
