Silver is a white metallic element, harder than gold, softer than copper and second only to gold in malleability and ductility. Represented on the Periodic Table of the Elements by the symbol Ag, silver is an excellent conductor of heat and electricity. Silver is considered one of the noble metals because of it is excellent resistance to oxidation. Historically, silver has played a prominent role in the production of jewelry and objets d’art and is usually alloyed with another metal to harden it enough to maintain the desired shape and details imparted to it.
At times throughout history silver was valued more highly than gold. When you examine the quantities of silver used in jewelry, its use outweighs all other precious metals by a large factor. This versatile white metal also triggered far more technological advances in the field of mining and metallurgy than its other precious metallic cousins. Entire economies have depended on its availability and the access to silver deposits has swung wars and as a result history.
Two or more elemental metals mixed to form a homogeneous mass are an alloy. Sometimes metals are alloyed with a non-metal such as carbon. The newly formed metal is usually harder, more durable, a different color and less malleable than the original components. Precious metal alloys remain precious as long as the precious metal dominates the mix and is kept in certain proportions.
.800 silver is an alloy of silver that is 800 parts silver and 200 parts other metals. It is also referred to as International Coin Silver. This alloy was common in the 19th and early 20th centuries on the European mainland but was not used in jewelry in the United States. 800 silver was the alloy of choice for pieces decorated with niello because it can withstand high firing temperatures better than alloys with higher silver content.
Britannia silver a silver alloy composed of 95.84% silver and 4.16% copper. English Parliament introduced the standard in 1697 in an attempt to deter the melting of sterling silver coins by making a higher standard for other items made of silver. In 1720 silversmiths were again allowed to use sterling silver, making Britannia silver an optional alloy.
Between 1687 and 1720 Britannia silver was marked with a woman’s figure (Britannia) and a lion’s head erased. Since 1999 Britannia silver has been marked with the fineness hallmark 958 inside and oval. The symbol of Britannia became optional. The Royal Mint has issued “Britannias” since 1998, a silver bullion coin, containing one troy ounce of silver, minted in Britannia standard silver.
A 90 percent fine silver content was the standard set in the United States of America for silver coins until 1966. Now no silver is used in U.S. coins. Other international coin silver standards range to an 80 percent silver content. The trend is to replace silver with nickel and aluminum in most countries’ currencies.
Fine silver is another way of saying pure silver.
Precium is a brand name for an alloy of silver and palladium. It was developed by Handy & Harman in New York and patented on April 9, 1974. It has an antique white color with a precious metal content of greater than 87% and is also tarnish resistant and very heavy in weight.
Plated and Filled Silver
From the FTC Guides:
An industry product may be described or marked as “vermeil” if it consists of a base of sterling silver coated or plated on all significant surfaces with gold, or gold alloy of not less than 10 karat fineness, that is of substantial thickness and a minimum thickness throughout equivalent to two and one half (2 1/2) microns (or approximately 100/1,000,000ths of an inch) of fine gold.
Hotel silver is the name given to white metals that resemble silver but do not contain any precious metals. These are mostly used as cutlery.
Tula silver is an alternate name for niello, named after the Russian town Tula where many of the 19th and early 20th-century niello works were crafted.
