Platinum History:
White metal platinum stretches back only a few hundred year. Despite being worked with some skill by South American Indians over 1,000 years ago, not until the Spanish conquest of the New World during the 15th and 16th centuries did news reach Europe

of this new metal that had been found . The Spanish first considered it a drag because it interfered with their gold mining activities. Platinum is an extraordinary properties did interest European scientists and was noted that it would not "melt by fire or by any of the Spanish arts." Heavier than gold and virtually impossible to destroy with gases or chemicals, in 1751, platinum was recognized as a newly discovered element.

What is Platinum?
Platinum jewelry is purity is generally at the 90 to 95% level and it is usually alloyed with other rare platinum group metals. This means you are getting more of the precious metal you are paying for and avoiding low value base metals that are commonly used in gold alloys. Platinum is 30 times more rare than gold. Platinum is naturally white and will not tarnish. White gold is achieved by "bleaching" yellow gold with other elements such as nickel and palladium. This process of whitening is not durable and thus yellowing and repeated rhodium plating are key disadvantages of white gold alloys.

  • Rare:
    There is very little platinum on this earth and it is found in very few places around the world. This exquisite metal is 30 times rarer than gold.

So, even though wearing it each and every day may leave an impression on the surface, it remains what it was - a symbol for all things eternal.
  • Versatile:
    Platinum is so versatile, that just one gram of the metal can be drawn to produce a fine wire over one mile (almost 2 km) long. This quality has enabled jewelers to create some amazing skilled platinum mesh accessories, which could not be fashioned from other precious metals. Platinum is also in demand in other fields - it is used in industry, most notably in catalytic converters. Platinum also plays an important role in medicine. It is not affected by the oxidizing reaction of blood, has excellent conductivity, and is compatible with living tissue. Because of these properties, platinum is used for pacemakers. At present, more than 50,000 people are living healthily on pacemakers. Platinum is a life-saving metal for these people.

Most jewelry items made of precious metal are stamped with information about the purity level of the metal content. Generally the stamp is placed in an inconspicuous place on the item so it does not detract from the design. Stamps will usually be located on the inside of the band on a ring, on the post or basket setting on a pair of earrings, on the bail (the part that the chain slides through) on a pendant. The term "karat" (usually abbreviated as "k," "K," or "Kt") refers to the relative purity of gold; pure gold is 24 karats. "Karat" is different from "carat," which is a metric unit of weight for gemstones.

Platinum Alloys:
Platinum is not a single metal, but a group of similar materials. The group includes platinum, iridium, palladium, ruthenium, rhodium, and osmium. Platinum is the most abundant. Rhodium is popular as a non-tarnishing plating for white gold, silver, and other platinum metals. All but osmium are used for jewelry. The most common alloys include 90% platinum and 10% iridium, or 95% platinum and 5% ruthenium. Ruthenium makes for the harder and stronger alloy.

Platinum Care:
Store platinum jewelry separate from other jewelry items so that they do not scratch or get scratched by your other jewelry items. Place your jewelry in a jewelry box. Clean your platinum jewelry periodically. This will ensure its fine appearance and will help it last. Clean platinum in the same way you clean other fine jewelry - using a pre-packaged jewelry cleaner or by soaking it in a mild solution of 50% ammonia and 50% warm water and then gently rubbing it with a soft cloth. Note that harsh chemicals such as ammonia should not be used on gemstones other than diamonds because it may damage them - consult a jewelry professional in-person for specific guidance in this matter as it applies to specific jewelry items. Have your platinum jewelry polished and cleaned by a qualified jeweler twice a year and more often if scratches appear. Remember that all metal can be scratched, however with platinum the metal has merely been displaced. Take your platinum jewelry to a qualified jeweler twice per year for inspection. Only allow a trained professional jeweler to work on your platinum jewelry. Adjustments, resizing, polishing and cleaning of your platinum jewelry should be provided by a trained bench jeweler. Do not wear your platinum or other fine jewelry when working with bleach or other harsh chemicals. Although the chemicals may not affect the platinum, they may discolor diamonds and other gemstones and can cause an allergic reaction with your skin if trapped between the ring and your finger.
