At Crystal mountain, Arkansas, and in the region around Hot Springs for about 40 miles, large veins of quartz are frequently met with in a red sandstone, the exact geological horizon of which has not yet been accurately defined. They are mined by the farmers, who bring them to Hot Springs in wagons and sell them to local dealers and tourists. At least $10,000 worth are annually sold to be taken away as mementoes. Great quantities of imitation (paste) diamonds are sold to the unwary as cut rock crystals, and quantities of foreign crystals as Arkansas quartz of local cutting.
Many localities in Colorado, notably Mount Antero, yield fine specimens of quartz. All along the Atlantic coast, at Narragansett Pier, Long Branch, Atlantic City, Cape May, Old Point Comfort, and other places, transparent pebbles are found in the sand and are much sought after by visitors, who often have them cut as souvenirs. At many such places the local lapidaries have been known to substitute for pebbles found on the beach foreign-cut quartz, cairngorm, topaz, crocidolite, moonstone from Ceylon, and even glass, obtaining twice the value of the foreign gem for the price of the supposed lapidary work. Many thousands of dollars' worth of such stones are sold annually. At all of these resorts large quantities of the quartz pebbles are cut into gems and seals, and all manner of ornaments are sold as having coming from the vicinity. Sometimes even the stones found by the visitors and intrusted to lapidaries for cutting are exchanged for cut stoues brought from Bohemia, Oldenburg and the Jura. Cutting is done abroad on so large a scale and by labor so poorly paid that the cut stones can be delivered in this country at one-tenth of the price of cutting here, as the rock crystal itself has but little value. In the West there are many dealers who sell so-called "Rocky Mountain Gems," the entire stock frequently not containing a genuine stone, all being glass imitations. The same is true of all the blue moonstones and various stones sold in great quantity at the World's Columbian Exposition.
Amethyst is found on Deer hill, at Stow, Maine, where there is a vein of amethystine quartz which has been traced fully one-quarter of a mile and has furnished thousands of crystals during the last twenty years. A few have been of some gem value. Among some found in 1885 was a remarkable mass that yielded a gem weighing 25 carats of the deep purple color of the Siberian amethyst. Fine amethysts have been obtained at Mount Crawford, Surry, Waterville, and Westmoreland, N«w Hampshire. At Burrillville and at Bristol, on Mount Hope bay, Rhode Island, fine amethysts were found and used as ornaments over sixty years ago. Crystals of fine quality, though not affording gem material, one weighing seven pounds, have been found in Tipper Providence township, Delaware county, Pennsylvania. Pine crystals and gems have been found in western North Carolina, and in Rabun county, Georgia. The mode of occurrence of the above gem is identical with
