Platinum is an extremely rare metal, even rarer than gold. There isn't much of it around and it has only been found in select locations across the planet. Platinum is a strong, dense metal, which allows it to be used in many different ways. Besides platinum jewelry, it is also used to make catalytic converters, and it is helpful in the medical field because it resists oxidation. As the perfect material for pacemakers, platinum not only makes lovely jewelry, but also helps save lives.
Despite its strength, platinum is a very supple, workable material, making intricate designs and details far easier to achieve than with gold. Since it is so pure, platinum jewelry is the perfect hypoallergenic accessory for those who cannot wear gold. Part of the reason people cannot wear gold is often associated with the alloys involved in the jewelry making process. Since platinum contains very little alloy, jewelry made with it is a good choice for those who are sensitive to metals.
Platinum jewelry is made from very pure platinum. As compared to gold, platinum falls between the 18-karat and 24-karat range, with 18 karat being approximately 75% pure and 24 karat being the purest. Since 18-karat jewelry is 75% pure, that means that the other 25% of the piece is an alloy, such as silver, zinc or copper. This simply means that platinum requires very little alloy to be combined with it in order to make jewelry.
Jewelry made with platinum is very sturdy and resilient, making it ideal for everyday wear. Like other types of metal jewelry, it can become scratched, but a scratch won't damage platinum in the same way that it damages other precious metals. Platinum jewelry will maintain its color, brilliance and weight even when scratched, while other metals may lose their luster or become blemished or discolored.
