subject: A Brief Introduction To The Historical And Commercial Presence Of Gemstones [print this page] Gemstones are the most sought after jewelry items found across the market these days. These stones are pieces of different minerals and are used for making designer jewelry or other adornments. These gemstones are available in different variety and their cost varies based on their availability, and other characteristic properties. These also have aesthetic values and are considered highly auspicious especially in the Hindu culture.
Every gemstone is classified based on different cultures but on a general scale, they are divided into two major categories precious and semi-precious stones. While under the category of precious stones, gems like Diamond, Ruby, Sapphire and Emerald are considered, the other gems are usually categorized under semi-precious. Though this technique is the ancient classification of gems, modern gemologists use technical terms for the classification process. These include factors of identification such as chemical composition, habit, etc.
Properties such as refractive index, specific gravity, hardness, dispersion, cleavage, fracture and luster are also used for the identification of gemstones. Today there is a huge demand of gemstones and hence even companies have started to manufacture artificial gems. These stones are quite like other gemstones but are considerably cheaper than the original varieties, for example, cubic zirconia is an imitation of real diamond. Though the artificial gemstones have the look and color of real stones, the physical and chemical characteristics are very different far from matching. But these imitation gemstones are not similar to the stones which undergo lab manufacturing.
Before you purchase a costly gemstone, you must look for grading details which are offered by many institutes across the world like IGI, GIA, and AGS etc. It must be noted that a universal system for gemstone grading does not exist. Whereas historically gemstones were graded by using naked eye however in today's time the American Gemological Institute has developed a system which is widely used.
