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, such as the 10oz, 1oz, 10 g, 100 g, 1 kg, 1 Tael, and 1 Tola. 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. Efforts to combat gold bar counterfeiting include kinebars, which employ a unique holographic technology and are by the Argor-Heraeus refinery in Switzerland. 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. Coins may be from a variety of dealers both large and small. Fake gold coins occur, and are usually made of gold-plated lead.

Rings

A finger ring is a circular band worn as a type of ornamental jewelry around a finger; it is the most common current meaning of the word ring. Other types of metal bands worn as ornaments called rings, such as arm rings and neck rings. Rings worn by both men and women and can be of any quality. Various ring shapes and styles exist. The following are but a few. Flat wedding bands are the simplest form of ring. A flat wedding band consists of a strip of metal bent around into a loop and joined where the ends meet. Half-round rings, also called D-shape rings, are flat wedding bands filed half-round on the outside. Sleeve rings are rings that consist of a thin inner ring or sleeve, with several other rings stacked onto it to form one solid ring. Either the rings soldered onto the sleeve or the ends of the sleeve can be upset to keep them all together. A little of both can also be done. Solitaire rings are rings with a single large stone as a centerpiece, usually a diamond. Eternity rings are rings with stones, usually diamonds, of the same cut and size, set in one row all around the ring. The stones are usually round or square, and the setting is usually either claws or a channel setting. When the stones do not continue around the entire ring, but stop halfway around the finger, it is a half-eternity ring. Trinity rings or Trilogy Rings are three rings worn at one time. Cluster rings are rings with a group of stones in a cluster setting, forming the focal point of the ring. The cluster setting usually consists of one large stone in the center surrounded with several smaller stones. Tension Rings are a type of ring in which a single gemstone is held in place by pressure rather than prongs, a bezel or other mounting. The metal setting is actually spring-loaded to exert pressure onto the gemstone. In the United States and Canada, ring sizes specified using a numerical scale, with quarter and half sizes. An increase of a full size is an increase of 0.032 inch in diameter, or roughly 1/10 inch in inside circumference. Generally, sizes in quarters and halves will not relate conventionally to anything on any known ruler. On one finger alone, a person may vary more than a whole ring size- depending on time of day, work performed, and other swelling-inducing activities/conditions. Therefore, in most cases quarter-sizes are meaningless unless one needs precise accuracy with a particular ring.
