Monumental Quartz mineral crystal bed of huge proportions, displaying large points in clusters, excellent clarity to the points, as seen in the images above. The rare sized crystal bed is displaying all the sort-after attributes from one of the most important Quartz locations. The pre-eminent group of mines of this location have produced crystal beds which now reside in museum collections around the world. This crystal bed is from that stable and is an opportunity to own a specimen which is part of that North American specimen mineral history.


An example of the finest museum quality cluster bed of Quartz points. The clarity of these crystal points is remarkable. In prehistory milky Quartz through the action of deposition of minerals through the hot water which was laid down in the region forming the mountain ranges of North America. This outstanding crystal bed is typical of the best the region has to offer. Quartz in the Ouachita Mountains laid down in the late Palaeozoic era, between two hundred and eighty to two hundred and forty-five million years ago, created the Quartz vein near Little Rock, Arkansas, which is around sixty feet thick and runs from Oklahoma to Arkansas. Quartz and other mineral veins deposited from hot water in the closing stages of mountain building. Quartz is a hard mineral and has been admired from prehistory for its similarities when cutting to diamond. In fact in Arkansas Quartz are cut to imitate diamonds and are termed Arkansas Quartz diamonds.


Arkansas state between Oklahoma and Tennessee in North America is the likely origin of some of the finest Quartz specimens ever found. Since prehistoric eras, early man had fashioned tools from quartz and admired the clarity and qualities of Quartz. The Ouachita Mountain range which stretches for about 170 miles is no exception, Indian peoples tools and points which have the telltale marks of being chipped out of Quartz. The vein of Quartz in this mountain range runs approximately 30 to 40 miles and is centred around Little Rock, Arkansas.


Early in the history of commercial mining the hellcat brand of mining and state claiming existed, wherever a miner dropped his pick was his claim. No government licenses were required, and miners left to their own devices up to World War II. During WWII, an urgent need for oscillator-grade Quartz for the manufacture of communications equipment brought about a rapid expansion of federal government mining. That industry saw an end to the traditional wildcat mining. In 1943 the mines produced only around four thousand pounds of Quartz for federal use.


Post war the mining under license dwindled and with the introduction of commercially grown artificial Quartz put pay to the excavation of great quantities of Quartz, down to meagre amounts. Now collectors, tourists and museums are the main force behind the extraction of the fine quality Quartz clusters and individual specimen points.


Determining the age of Quartz minerals is a fickle process as crystals grow in environments of certain pressures, heat and with certain chemical elements in cavities of the earth, these crystals grow and fill the cavities. When the environment changes for various reasons, the crystals may stop growing. At what point the crystal started to grow or stops its growth cycle is undeterminable.


Quartz veins of the Ouachita Mountain region in Arkansas were laid down in the late Palaeozoic era around 280 to 245 million years ago, the Quartz veins are between sixty and one hundred feet thick and run from Oklahoma to Arkansas. Quartz and other mineral veins were deposited from hot water in the closing stages of mountain building.


Part of the trigonal crystal system where the most popular crystal form is a six-sided prism terminating externally to a pyramid point. Often twinned, distorted, or intergrown with surrounding quartz crystals. Crystals form in clusters or 'crystal beds'. Clusters consist of unconstrained growth into a void, usually attached to the matrix at the base of the Quartz structure.
