Amethyst Galleries' Mineral Gallery "The First Internet Rock Shop!" THE GEMSTONES "The Flowers of the Mineral Kingdom" As colorful as the rainbow and as sparkling as fine leaded crystal, gemstones have captured the imaginations and desires of men and perhaps especially, women, for ages. The pursuit of gems have become the subject of legends, fairy tales, epics, and major motion pictures (" Romancing the Stone ", for one). Today, more fine gemstone specimens are available to the average person than at any time in history. What makes a gemstone? Generally speaking, a gemstone is a stone that is beautiful, rare, and durable (resistant to abrasion, fracturing and chemical reactions). Some minerals can be very beautiful, but they may be too soft and will scratch easily (such as the mineral fluorite ). Fluorite is extremely colorful and pretty but has a hardness of only 4 on the Moh's hardness scale and has four perfect cleavage directions, which makes it only an oddity as a cut gem. Others are too common and are given a semi-precious status (such as agate ). Most gemstones have good hardness (above 5) and a high

Care The jewelry industry recognizes the highest quality gemstones by purity of their hue, the depth of tone, and the color saturation. The best value is in colors that include "slight" traces of other colors, are not too light or dark, and have a lot of saturated color. Blue Nile offers some of the highest-quality colored gemstones available. Unlike diamonds, with gemstones there isn't an "ideal" cut geometrically configured for maximum brilliance. But a high-quality gemstone cut is one that presents the most even color, exposes the fewest inclusions, and displays the majority of the gemstone weight when set in jewelry. Nearly all colored gemstones available have been enhanced. Gemstones that have not been enhanced but exhibit desirable color and clarity are very recognizable by the extravagant price they command. Some enhancements, such as heating, are an expected part of the polishing and finishing process and are accepted by the jewelry industry, and by Blue Nile. Gemstones Color Clarity Cut Size ...

Links Gemstones As defined here, a gem is any jewel, whether stone or pearl, having value and beauty that are intrinsic. A gemstone or gem material is a stone or material from which a gem may be cut. Gems are used for personal adornment, display, or in manufactured objects of art because they possess beauty, rarity, and durability. Arkansas has within its borders several stones or materials which, by popular definition, are considered gemstones. They are: amber diamond onyx pearls (fresh water), quartz (several varieties), and turquoise . In 1995, Arkansas ranked 3 rd in the nation in value of gemstones produced ($4.89 million). Amber Amber is brittle, yellowish to brownish, translucent to transparent, fossilized tree resin. It may enclose insects and other organisms. Gem-quality amber takes a high polish. Gem-grade amber is often used to make faceted beads and irregular shaped polished drops. Larger pieces may also be manufactured into mouth pieces for pipes or cigarette holders, although less expensive plastics now substitute almost entirely for this market. Amber has a low specific gravity (1.0-1.1) and is soft (2-2.5 on Mohs scale). Amber burns with a strong "tar" odor due to its hydrocarbon composition. Amber is also soluble in some petroleum-based solvents, such as acetone.
