Precious Metals

Sterling Silver

Sterling Silver
Silver is one of the first metals to be used by humans. It is also the most reflective of all the metals and can be polished to a higher sheen than platinum. In fact, the chemical symbol for silver, Ag, is derived from the Latin word argentum, meaning ‘white and shining.’ It is extremely malleable and resists oxidation from exposure to the atmosphere. Silver also has the highest thermal and electric conductivity of any substance. Silver is widely distributed in nature, but the total amount is quite small when compared with other metals. Unlike gold, silver is present in many naturally occurring minerals.

Gold

Gold
Gold is a chemical element that, aside from its extraordinary luster, has amazing physical characteristics that make it extremely well suited for use in jewelry making. One ounce (28 grams) of gold can be hammered into 187 square feet of extremely thin sheets called gold leaf. Gold does not tarnish or corrode and it can be re-melted and used again to create new designs.

Platinum

Platinum
Called the “King of Metals”, platinum is a very heavy (nearly twice the weight of gold), silver-white metal that is very ductile. Although it is a soft metal, platinum is not easily scratched and is very strong and durable. In fact, as the strongest precious metal used in jewelry, platinum also has a high melting point and good resistance to corrosion and chemical attack. Small amounts of iridium and ruthenium are commonly added to it, to give it a harder, stronger alloy that retains the advantages of pure platinum. The platinum family actually comprises six metals: platinum, palladium, iridium, osmium, rhodium and ruthenium. The six metals are generally found together in nature, with platinum and palladium being the most abundant, and the other four being more rare.
