Gold has had an inestimable effect on human history. It has been crafted, mined, worshipped, plundered, fought over and traded for thousands of years. Today, the search for gold is as eager as ever, despite the vast stocks stored away in underground bunkers. So why has gold held this fascination for humanity?

A popular misconception is that natural gold has cooled from a molten state. In fact,Gold Rates Increasing Day By Day Articles gold is transported though the Earth’s crust dissolved in warm to hot salty water. These fluids are generated in huge volumes deep in the Earth’s crust as water-bearing minerals dehydrate during metamorphism. Any gold present in the rocks being heated and squeezed is sweated out and goes into solution as complex ions. In this form, dissolved gold, along with other elements such as silicon, iron and sulphur, migrates wherever fractures in the rocks allow the fluids to pass. This direction is generally upwards, to cooler regions at lower pressures nearer the Earth’s surface. Under these conditions, the gold eventually becomes insoluble and begins to crystallise, most often enveloped by masses of white silicon dioxide, known as quartz. This association of gold and quartz forms one of the most common types of "primary gold deposits". Gold occasionally takes forms that lend themselves to descriptive terms such as wire gold, nail gold, mustard gold and paint gold. While all gold has a crystalline structure, distinct crystals showing well-formed faces are relatively rare. They require special conditions to form, in particular space in which to grow. Hence crystals of gold are found in cavities in quartz reefs or in softer minerals such as iron oxides where they have been able to push aside the enclosing material as they grew. Gold crystallises in the cubic system, and perhaps the most common variety is the eight-sided octahedron.Its initial attraction is its color, an eye-catching and characteristic bright yellow with a soft metallic glint. Gold’s pleasant ‘feel’, a combination of its density (19.3 grams per cubic centimetre when pure) and coldness, cannot be duplicated by any other metal. Furthermore, gold can be hammered into very thin sheets or leaves, drawn into wire, cast, carved, polished, heated without tarnishing and easily combined (alloyed) with other metals.Gold Rates
