COPPER (METAL USED IN JEWELRY)

The copper metal has always been in use for over ten thousand years. It is an essential mineral which can be found not only in plants but also in the human body. Copper, which behaves like an antimicrobial substance, is known to inhibit or kill fungi, bacteria, viruses or any other harmful micro-organism. It is a trace element, and its importance in the human body for the healthy functioning and development of the heart, the bones, the immune system and the skin cannot be over-emphasized. Copper, in its purest form, is soft, malleable and its use in the jewelry industry cannot be quantified. Copper has also found other uses as a conductor of heat, currency (copper is the chief element utilized in the United States penny). Copper is used in several medical instruments, on sculptures (the Statue of Liberty, which is one of the largest statues in the world, is made predominantly of copper). The environmental friendliness of copper has ranked it as the third most recyclable metal, and its durability accounts for the present-day use of over eighty percent of copper which was mined more than a few thousand years ago.

History of the Metal

Copper is classified as one of the oldest metals in existence. Archeological evidence has revealed that copper was mined by prehistoric men just about thirteen thousand years ago. The process of refining the mineral ore took much longer before being established in the Middle East.

Egyptians are credited as the first to conceive and create alloys from copper. Brass (a combination of zinc and copper) and bronze (a mixture of tin and copper) are some of the metal alloys created by the Egyptians. Any person with a large cache of copper, whether in pure or alloyed form, was highly regarded and given a respectable status in the society in those days.

The malleability of the copper mineral ore made it an excellent choice for jewelers as they used it to craft crowns for royalty as well as other elements which befitted their stations. The use of copper was not exempted from spiritual and religious ceremonies and medical practices as well. Owners of copper and copper jewelers enjoyed important high social status in those prehistoric days.

In the Americas, early men also made use of copper to create earrings and beads as well as in the treatment of wounds and skin diseases. When the Europeans arrived at the continent, copper bracelets gained prominence as a medium of exchange for the American natives. Even in this day and age, American Natives still produce pieces of jewelry made from copper in the form of earrings, pendants and bracelets. In modern day fashion circles, copper is still highly revered and used by celebrities as a jewelry item.

But over time, due to repeated use as well as exposure to dust, sweat, and humidity, the pink and shiny luster of the metal begins to darken into an unattractive brown color. Most times, as a result of oxidation, a green patina is created which further dulls the natural color of the metal. When you notice this change on your copper jewelry, it only means it’s time for you to get it cleaned by jewelers or artisans in your neighborhood or do it yourself.
