Sapphire is a gemstone variety of the mineral corundum, an aluminum oxide, when it is a color other than red or dark pink, in which case the gem would be a ruby, considered a different gemstone. Trace amounts of other elements such as iron, titanium, or chromium can give corundum blue, yellow, pink, purple, orange, or greenish color. Pink-orange sapphires are padparadscha. Pure chromium is the distinct impurity of rubies. However, a combination of e.g. chromium and titanium can give a sapphire of a color distinct from red. Sapphires are a part of many jewelry settings. Sapphires found naturally by searching through certain sediments or rock formations, or manufactured for industrial or decorative purposes in large crystal boles. Because of the remarkable hardness of sapphires , sapphires are used in some non-ornamental applications, including infrared optical components, such as in scientific instruments; small, high-durability windows ; wristwatch crystals; and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics . The sapphire is one of the two or three gem-varieties of corundum, with another one being the red or deep pink ruby. Although blue is their most known color, sapphires make up of any color of corundum except for red. Sapphires may also be colorless, and found in shades of gray and black. The cost of natural sapphires varies depending on their color, clarity, size, cut, and overall quality - as well as their geographic origin, oddly enough. Significant sapphire deposits are found in Eastern Australia, Thailand, Sri Lanka, Madagascar, East Africa, and in North America in a few locations, such as at Gem Mountain, and in or near the Missouri River in the region around Helena, Montana. Sapphire and rubies found together in the same area, but one gem is usually more abundant. Color in gemstones breaks down into three components: hue, saturation, and tone. Hue is the color of the gemstone. Saturation refers to the vividness, brightness, or colorfulness of the hue and tone is the lightness to darkness of the hue. Blue sapphire exists in various mixtures of its primary and secondary hues, various tonal levels and at various levels of saturation. Blue sapphires evaluated based upon the purity of their primary hue. Purple, violet, and green are the most common secondary hues found in blue sapphires. Violet and purple can contribute to the overall beauty of the color, while green considered distinctly negative. Blue sapphires with up to 15% violet or purple are to be of fine quality. Blue sapphires with any amount of green as a secondary hue are not fine quality. Gray is the normal saturation modifier or mask found in blue sapphires. Gray reduces the saturation or brightness of the hue and therefore has a distinctly negative effect. The color of fine blue sapphires described as a vivid medium dark violet to purplish blue where the primary blue hue is at least 85% and the secondary hue no more than 15% without the least admixture of a green secondary hue or a gray mask. Yellow and green sapphires found regularly. Pink sapphires deepen in color as the quantity of chromium increases. The deeper the pink color the higher their monetary value as long as the color is trending towards the red of rubies. Sapphires also occur in shades of orange, brown, and colorless sapphires sometimes used as diamond substitutes in jewelry. Padparadscha sapphires often draw higher prices than many of even the finest blue sapphires. Recently, more sapphires of this color have appeared on the market result of a new artificial treatment method that is lattice diffusion.

Gold Investors Undeterred

Gold investors undeterred by high prices. Gold might be a luxury most can live without when times are hard, but for cautious investors, it has become a matter of necessity. Gold is the most popular precious metal investment. Investors generally buy gold as a hedge or safe haven against any economic, political, social, or fiat currency crises. The gold market is also subject to speculation as other commodities are, especially with futures contracts and derivatives. The history of the gold standard, the role of gold reserves in central banking, gold's low correlation with other commodity prices, and its pricing in relation to fiat currencies during the financial crisis suggest that gold has features of being money. Gold has been throughout history as money and has been a relative standard for currency equivalents specific to economic regions or countries. The most traditional way of investing in gold is by buying bullion gold bars. In some countries, like Argentina, Austria, Liechtenstein and Switzerland, these can easily be at the major banks. Alternatively, there are bullion dealers that provide the same service. Bars are available in various sizes. For example in Europe, Good Delivery bars are approximately 400 troy ounces. 1 kilogram is also popular, although many other weights exist. Bars generally carry lower price premiums than gold bullion coins. However, larger bars carry an increased risk of forgery due to their less stringent parameters for appearance. While bullion coins can be easily, weigh and measure against known values. Most bars cannot, and gold buyers often have bars re-assayed. Larger bars also have a greater volume in which to create a partial forgery using a tungsten-filled cavity, which may not be assay. Gold coins are a common way of owning gold. Bullion coins price according to their fine weight, and a small premium based on supply and demand. The Krugerrand is the most widely held gold bullion coin, with 46,000,000 troy ounces in circulation. Other common gold bullion coins include the Australian Gold Nugget (Kangaroo), Austrian Philharmoniker (Philharmonic), Austrian 100 Corona, Canadian Gold Maple Leaf, Chinese Gold Panda, French Coq d’Or (Golden Rooster), Mexican Gold 50 Peso, British Sovereign, and American Gold Eagle.The gold market is subject to speculation as other commodities are, especially through futures contracts and derivatives. The supply and demand as well as speculation controls the price of gold. Unlike most other commodities, saving gold and disposal plays a larger role in affecting its price than its consumption.
