Silver is much more plentiful than platinum or gold and is much less expensive. Sterling silver is usually 92.5% silver and 7.5% copper.
Gold is traditionally seen in yellow and white colors, but can also be available in rose or green on occasion. For example, 18kt gold contains 18/24 gold and 6/24 alloy, while 14kt gold contains 14/24 gold and 10/24 alloy. Gold's purity is measured in karats, which indicate out of 24 parts how many parts are gold. Gold is mixed with alloys like copper, silver, nickel, and zinc to give different colors, strength, and durability. Pure 24 karat gold is rarely used in jewelry because it is too soft for frequent wear. 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. Its purity makes it hypoallergenic, perfect for people who are sensitive to the alloys used in gold. Platinum is the heaviest of all the precious metals weighing approximately twice as much as karat gold. Platinum is generally 95% pure and does not tarnish or lose its rich white luster. Each choice has its own qualities, so base your choice on the ones that you value most.
Today, alternative metals like sterling silver, titanium, and stainless steel give you additional options in look, strength, price, etc. 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. There are a variety of metals choices available for jewelry.
