SilverSilver is a precious metal that has been used for thousands of years for various purposes such as ornaments, tableware, jewelry, photography and money. Its value as a precious metal was long considered second only to gold and in Ancient Egypt and Medieval Europe, it was often valued more than gold. The principal sources of silver are obtained from Canada, Mexico, Peru, Australia and the United States. However, Mexico is the largest producer of silver.
Characteristics of Silver
Silver is one of the chemical elements in the periodic table and is called Ag, short from the Latin term Argentum. It is a brilliant, white lustrous transition metal that is very ductile, malleable and endures a high degree of polish.
Sterling silver is composed of 92.5% silver alloyed with copper to strengthen it. Silver has one of the highest reflectivity of any metal, giving it unmatched brilliance, making it perfect for jewelry designs. Silver also has extremely high electrical conductivity and thermal conductivity. Despite all these wonderful properties silver is relatively abundant and easy to extract from ore, so it is, at the same time, relatively affordable making it ideal for jewelry that will appeal to a wide audience.
Silver Plating
The process by which one metal is coated with another using electricity, known as electroplating.
Nickel
Many times nickel, another hard metal known also as Ni, is placed between the coating and the silver because it facilitates the adherence and luster of the plating to the metal. When used in silver jewelry, this can cause irritation to those who are sensitive to nickel or have nickel allergies. For that reason, there is nickel-free jewelry available. Although, FashionIslandJewelry.com still carries some jewelry with nickel plating, 95% of our sterling silver jewelry is nickel-free and all of our nickel-free jewelry is clearly marked on the site.
* If you are an international customer, please note that use of nickel and nickel based alloys in jewelry may be illegal in your country. For example, European countries have officially banned nickel and nickel based alloys in jewelry due to the high number of nickel allergies.
Rhodium
Rhodium is a hard, durable, silvery-white metallic element that is used to form high-temperature alloys with platinum and is then plated on other metals to produce a durable corrosion-resistant coating. Rhodium, also known as Rh, is a member of the platinum group and found in platinum ores. It has a higher melting point and lower density than platinum. Rhodium is a very expensive metal, even more so than gold. Due to the scarcity of the metal, it commands a high market price.
Sterling silver jewelry that is plated with rhodium is resistant to scratching, abrasion and corrosion. As mentioned above, sterling silver has a tendency to tarnish rather quickly when exposed to harsh contaminants, such as sulfur and many others that are found all around us. Contact with skin oils and perfumes may also discolor silver, which requires frequent cleaning and polishing. Since rhodium plating is highly acid and chemical resistant, it will withstand such contact. Consequently, sterling silver is an ideal candidate for rhodium plating. In addition, rhodium is also frequently used to give silver jewelry a beautiful finish.
Silver Jewelry
The metal silver has been chosen for its beauty and luster in the manufacture of jewelry and silverware. Because it is malleable and easy to work with, silver has been fashioned in to rings, bracelets, earrings and other jewelry pieces. However, silver has a low resistance to pressure and can be easily bent. To make silver tougher and more durable, silver is often alloyed with other metals, which results in different types of silver. Based on the content of the other metals mixed in to the silver, silver is usually identified by hallmarks. A hallmark is generally an indication of metal content, purity and quality that is marked on individual pieces. Therefore, pieces using sterling silver are commonly tagged or engraved with 925 Silver or SS.
