There are a variety of metals choices available for jewelry. Whether you like the allure of platinum or the range of options with the classic gold, you will find a number of stylish pieces, sometimes even combining the two metals. Today, alternative metals like sterling silver, titanium, and stainless steel give you additional options in look, strength, price, etc. Each choice has its own qualities, so base your choice on the ones that you value most.
Platinum is generally 95% pure and does not tarnish or lose its rich white luster. Platinum is the heaviest of all the precious metals weighing approximately twice as much as karat gold. Its purity makes it hypoallergenic, perfect for people who are sensitive to the alloys used in gold. Platinum is also known for its strength and pliability, just one gram of platinum can be drawn into a fine wire over one mile long.
Sterling silver is usually 92.5% silver and 7.5% copper. Silver is much more plentiful than platinum or gold and is much less expensive. It takes on a much higher polish than any other metal, but it does tarnish. The tarnish can be removed, but silver requires much more care than other metals.
Palladium is a silver-white metal that resembles Platinum, however, it is slightly harder than Platinum so it will be more resistant to scratching.
Titanium is a light, strong, and corrosion-resistant metal. Titanium offers you seven times the strength of platinum at about 1/3 of the weight. It is the hardest natural metal on earth and therefore offers more scratch resistance than gold or silver. In addition, titanium is also hypoallergenic. When ordering titanium rings, be extra sure about your ring size. The biggest drawback of titanium rings is that they cannot be sized by traditional ring sizing methods.
Stainless steel is a low cost alternative to traditional metals. It is naturally hypoallergenic and will not rust or tarnish. Stainless Steel will not break or bend under normal usage and is stronger than any other alloy.
Cobalt has a similar look to platinum, with great strength and light weight. Because of its temperature stability, cobalt alloys are often used in engine turbines and surgical implants.
Zirconium is utilized in nuclear reactors and explosive wartime applications. It is very resistant to decay and heat. While most commonly mined from South Africa and Australia, zirconium has also been found in meteorites and moon rocks. It is naturally a silver grey color with a darker oxidized layer.
