Platinum is a durable naturally occurring element that has grown in popularity more than ever before. Considered an upgrade to the standard white gold option for its purity, strength and unique characteristics, platinum is denser and more expensive than white gold. Unlike white gold, platinum is not coated but changes from a bight white polished metal to a matted patina and is used in all ornamental jewelry from engagement rings to bracelets.
Platinum jewelry can be crafted with a variety of purity levels. Traditionally, the two most common options for jewelry are listed below and will be stamped or hallmarked onto the article of jewelry:
Osmium is a naturally occurring alloy of iridium and osmium which can be found in platinum-bearing rivers which can be found in Russia, as well as North America & South America
Iridium can be found with platinum in alluvial deposits. An alluvial deposit is simply a fancy word for clay or silt runoff where a river slows down and deposits valuable materials. It is also a byproduct of nickel mining and processing.
Ruthenium is generally found in ores within other platinum group metals, it can also be found in Russia, North America & South America.
Rhodium has great value to jewelry industry. It occurs in ores mixed with other elements such as palladium, silver, platinum, and gold. Rhodium can be found in the Ural Mountains, North & South America and is used to plate white gold jewelry to create a brilliant white finish.
Palladium can be found as a free metal and can be alloyed with platinum & gold in select deposits in Eurasia, Australia, Ethiopia, South & North America
