Gemstones by Donald W
GEMSTONES By Donald W. olson Domestic survey data and tables were prepared by Nicholas A. Muniz, statistical assistant, and the world production table was prepared by Glenn J. Wallace, international data coordinator. In this report, the terms “gem” and “gemstone” mean any gemstones and on the cutting and polishing of large diamond mineral or organic material (such as amber, pearl, petrified wood, stones. Industry employment is estimated to range from 1,000 to and shell) used for personal adornment, display, or object of art ,500 workers (U.S. International Trade Commission, 1997, p. 1). because it possesses beauty, durability, and rarity. Of more than Most natural gemstone producers in the United states 4,000 mineral species, only about 100 possess all these attributes and are small businesses that are widely dispersed and operate are considered to be gemstones. Silicates other than quartz are the independently. the small producers probably have an average largest group of gemstones; oxides and quartz are the second largest of less than three employees, including those who only work (table 1). Gemstones are subdivided into diamond and colored part time. the number of gemstone mines operating from gemstones, which in this report designates all natural nondiamond year to year fluctuates because the uncertainty associated with gems. In addition, laboratory-created gemstones, cultured pearls, the discovery and marketing of gem-quality minerals makes and gemstone simulants are discussed but are treated separately it difficult to obtain financing for developing and sustaining from natural gemstones (table 2).

It is a colorful bird with a distinctive facial pattern and a mottled brown back. The male has blue-gray wings and the female has mottled brown wings. Though common throughout North America, they are frequently spotted in Yellowstone National Park. They have many nicknames, such as ‘K-bird’, ‘sparrow hawk’, and ‘Mom’s falcon’.

Prospecting for Diamonds in Kimberlite January 2014 by W
Prospecting for Diamonds in Kimberlite January 2014 by W. Dan Hausel Kimberlite is just one of several rock types that contain diamond. Even so, only two rock types contain commercial amounts of diamonds—kimberlite and olivine lamproite (as well as placers derived from the erosion of these rock types). Commercial amounts of diamonds will likely be discovered in other rock types in the future. These were discussed in a 1998 book, Diamonds and Mantle Source Rocks in the Wyoming Craton with a Discussion of Other US Occurrences, and a 2002 book entitled, Diamond Deposits. Both books can be found by searching the author’s name on Amazon. To date, diamonds have been found in many states in the US—notably Arkansas, California, Colorado, Wyoming and Michigan. Most people assume kimberlite was discovered in South Africa, where it received its namesake at the diamond mines of Kimberley. Search either Google Earth or Flash Earth for “Big Hole Kimberley, South Africa” to see the original mine and also look three to five miles to the southeast at the famous Bulfontein, DuToitspan and Wesselton diamond mines. After you learn a little about the characteristics of kimberlite pipes, you will want to revisit the region around Kimberley because there are anomalies that are likely unmined and possibly undiscovered kimberlites. Kimberlite was actually discovered in the US in the Ithaca, Manheim and Syracuse regions of New York in 1837 where it was described as mica peridotite. Years later, kimberlite was found in Kentucky in 1884 in the chigger infested areas of Ison Creek and Hamilton Branch, two years prior to mica peridotite at Kimberley, South Africa being branded “kimberlite” by Carvil Lewis. -

Diamonds Have Been Found in Placers in North America Derived from Unknown Sources
DIAMOND DEPOSITS OF THE NORTH AMERICAN CRATON – AN OVERVIEW By W. Dan Hausel W. Dan Hausel Geological Consulting LLC, Gilbert, Arizona 85233 [email protected] ABSTRACT Diamonds have been found in placers in North America derived from unknown sources. Others were recovered from glacial deposits from distant lands. The number of placer diamonds found in North America indicates that several source deposits would be discovered. Some discoveries initially led to developments of small mines in Murfreesburo, Arkansas (Prairie Creek) and the Colorado-Wyoming State Line district (Kelsey Lake). However, world-class diamond deposits have eluded the United States to date, but have now been found in Canada that led that nation to becoming a major source of gem-quality diamonds over a very short period of time. Canada now ranks as the third largest diamond producer of gem-quality diamonds in the world, which followed the development of their first mine (Ekati) in 1998 and second mine (Diavik) a few years later. A third mine was recently dedicated (Jericho) and two additional mines are under development – all world-class deposits! With thousands of additional discoveries, other diamond mines will be developed in the future of Canada. The timing of this diamond boom and rush occurred at a promising time, when major diamond mines in Africa, Australia and Russia were showing declining production. Even though favorable Cratonic (Archon) basement rocks extend south of Canada under large portions of the United States, essentially all meaningful exploration has been confined to Canada over the past 25 years. Reports of hundreds of diamonds along with hundreds of kimberlitic indicator mineral anomalies, kimberlites, lamproites, lamprophyres and some distinct geophysical anomalies in the US, would lead one to anticipate that exploration could result in significant discoveries in the US – however, the political climate in the US remains archaic at best for exploration. -
Mineral Commodity Summaries 2002--Gemstones
68 GEMSTONES1 (Data in million dollars, unless otherwise noted) Domestic Production and Use: Total U.S. gemstone output has decreased in recent years owing to a decline in foreign demand for freshwater shell, a major component of the domestic industry. Domestic gemstone production included agates, amber, beryl, coral, garnet, jade, jasper, opal, pearl, quartz, sapphire, shell, topaz, tourmaline, turquoise, and many other gem materials. Output of natural gemstones was primarily from Tennessee, Arizona, California, Oregon, Utah, Nevada, and Idaho, in decreasing order. Reported output of synthetic gemstones was from five firms in North Carolina, New York, Florida, California, and Arizona, in decreasing order of production. Major uses were jewelry, carvings, and gem and mineral collections.

American Heritage Center University of Wyoming Guide to Wyoming and the West Collections Compiled By Rick Ewig, Lori Olson, Derick Hollingsworth, Renee LaFleur, Carol Bowers, and Vicki Schuster (2000) 2013 Version Edited By: Tyler Eastman, Andrew Worth, Audrey Wilcox, Vikki Doherty, and Will Chadwick (2012-2014) Introduction The American Heritage Center (AHC) is the University of Wyoming’s (UW) repository for historical manuscripts, rare books, and university archives. Internationally known for its historical collections, the AHC first and foremost serves the students and citizens of Wyoming. The AHC sponsors a wide range of scholarly and popular programs including lectures, symposia, and exhibits. A place where both experts and novices engage with the original sources of history, access to the AHC is free and open to all. Collections at the AHC go beyond both the borders of Wyoming and the region, and support a wide range of research and teachings activities in the humanities, sciences, arts, business, and education. Major areas of collecting include Wyoming and the American West, the mining and petroleum industries, environment and natural resources, journalism, military history, transportation, the history of books, and 20th century entertainment such as popular music, radio, television, and film. The total archival holdings of the AHC are roughly 75,000 cubic feet (the equivalent of 18 miles) of material. The Toppan Rare Books Library holds more than 60,000 items from medieval illuminated manuscripts to the 21st century. Subject strengths include the American West, British and American literature, early exploration of North America, religion, hunting and fishing, natural history, women authors, and the book arts.
