What is Silver?

Silver chemical symbol and atomic number 47 (: άργυρος <Argyros> Latin, Argentum, or Indo - European root * arg for "gray" or "shining" in Greek) is a metallic chemical element with the AG. Soft, white, shiny transition metal, it has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. Its pure form, free (native silver) in metallic gold and other metals and minerals, such as argentite and chlorargyrite occurs naturally as an alloy. Most silver, copper, gold, lead, zinc, and is produced as a by-product of refining.

Silver is a very ductile malleable (slightly harder than gold), monovalent metal coins brilliant white metallic luster that can take a high level of gloss s highest electrical conductivity of all metals, even higher than copper, but the costs are becoming more and more widely used in place of copper for electrical purposes. Except radio engineering in the VHF and higher frequencies, where silver, including wires, improving the electrical conductivity of parts, widely used, particularly. During the Second World War, 13,540 tons electromagnets used for enriching uranium, mainly due to lack of copper used in time of war.

Gold Bonding - Makes Gold Value Higher

Gold Bonding is a bright, hard, durable finish for gold. This should not be confused with gold plating! Soldering gold jewelry that looks and feels a lot like gold Karat 14 or 18, not even a jeweler can visually tell the difference!

A term for gold yellow gold overlay welding or Contains. However, not all connections, gold is created equal. All our products are Gold Gold Bonded with 50 mils (or layers) of pure gold. 25 first layer of pure 24K gold. Monday is the 25th grade pure 14k gold. Thus, the concentration of gold All our products is a 24k concentration, but with the color 14k gold market.

Golden Links is proud of us here in the United States for quality control. Our manufacturer with experience over 30 years, is one of the few domestic manufacturers have quality control standards of Gold Bonding meet or exceed federal standards.

Gold Jewelry: Makes Gold Value Higher

The inclusion of a lifetime warranty certificate for each affiliate products Gold is to ensure total commitment to meet the federal standards.

How is the land.

Production process is as follows. We first start with a high quality metal base. Unlike other jewelry metals, which are used in the industry, which is about the same weight and flexibility of 14 and 18 carat gold, but more powerful. Then, just as the process of copper, gold and other metal jewelry »Power is connected to the brass to ensure an effective seal and to provide a smooth surface, but on the bright to apply the first layer 25 of the 24 carat gold. There are ... 24 carat pure gold. This makes our jewelry looks and feels like real gold at a fraction of the cost!

Unlike most manufacturers, the products go through a costly two-stage process. Thus, after the first 25 levels of 24 Karat gold is set, add 25 class 14 or 18 carat gold to be connected to the product.

Gold Mining - Gold Price is Raising

The city of Johannesburg located in South Africa was founded as a result of the Witwatersrand Gold Rush which resulted in the discovery of some of the largest gold deposits the world has ever seen. Gold fields located within the basin in the Free State and Gauteng provinces widely in strike and dip requiring some of the deepest mines in the world, with the Savuka and TauTona mines currently deepest gold mine in the world at 3,777 m. The Second Boer War of 1899-1901 between the British Empire and the Afrikaner Boers was at least partly over the rights of miners and gold gaining wealth in South Africa.

Other major producers are the United States, Australia, Russia and Peru. Mines in South Dakota and Nevada supply two-thirds of gold used in the United States. In South America, the controversial project Pascua Lama aims at exploitation of rich fields in the high mountains of Atacama Desert, at the border between Chile and Argentina. Today about one-quarter of the world gold output is estimated to originate from artisanal or small scale of mining.

Since the 1880s, South Africa was the source for a large proportion of the world's gold supply, with about 50% of all gold ever produced to be from South Africa. Production in 1970 accounted for 79% of world supply, which produces about 1,480 tonnes. Production for 2008 was 2,260 tonnes. In 2007 China (with 276 tonnes) overtook South Africa as the world's largest gold producer, the first time since 1905 that South Africa is not the greatest.

At the end of 2009, it is estimated that all the gold ever mined totaled 165,000 tonnes. Be represented by a cube with an edge length of about 20.28 meters. At $ 1600 per ounce, 165,000 metric tons of gold would have a value of $ 8.8 trillion.

Gold, Silver, Jewellery

Because of the softness of pure (24k) gold, it is usually mixed with base metals for use in jewelry, altering hardness and ductility, melting point, color and other properties. Alloys with lower caratage, typically 22k,, 18k 14k or 10k, contain higher percentages of copper, or other base metals or silver or palladium in the alloy. 

Unique Gold Jewellery

Fourteen and eighteen carat gold alloys with silver alone appear greenish-yellow and referred to as green gold. White gold alloys can be with palladium or nickel. White 18 carat gold containing 17.3% nickel, 5.5% zinc and 2.2% copper silvery appearance. Nickel is toxic, however, and its release from nickel white gold is controlled by legislation in Europe.

Fourteen carat gold-copper alloy is nearly identical in color certain bronze alloys, and both may be used to produce police and other badges. Eighteen carat gold containing 25% copper found in antique and Russian jewelry and has a, distinct though not dominant, copper cast, creating rose gold. Blue Gold is made with an alloy of iron and purple gold can be made by alloying with aluminum, although rarely done except in specialized jewelry. Blue gold is more fragile and therefore more difficult to work with when making jewelry.

Alternative white gold alloys are available based on palladium, silver and other white metals, but the palladium alloys are more expensive than those using nickel. High-carat white gold alloys are far more resistant to corrosion than either pure silver or sterling silver. Copper is the metal most commonly used base, resulting in a red color. Japanese Craft Mokume-Gane utilizing contrasting colors between laminated colored gold alloys to produce mapalamuting wood-grain effect.
