Gold does not change in color, rust or corrode or fade. Gold survives time. Also gold can be shaped to any size or shapes.
Now going back to gold, purity of gold is measure from 1 to 24. 24 karat (24K) is purest form of the metal. So when you hear 18k gold, it means 18/24 karat which is 75% of gold and 25% alloy. More alloy, or lower karat in gold, gold becomes much more strong.
Some people are allergic to nickel and should not wear white gold which contains Nickel. Some manufacturers use Palladium instead of Nickel. White gold which contains Palladium will be more expensive than yellow gold or white gold but it will be less expensive than Platinum.
PLATINUM
Platinum is often described as the purest, most precious metal. It was proclaimed by France’s Louis XVI to be “the only metal fit for royalty.” This honor is certainly merited. Platinum is one of the strongest, most durable metals on Earth. It has a luxurious silver sheen and a beautiful luster, yet it is hypoallergenic and resists tarnish. It won’t wear away, but rather develop and attractive satin finish. The world's most famous diamonds, including the Hope, Jonker I and Kohinoor, are all secured within the strong embrace of platinum.
18K GOLD
18K gold is the most popular engagement ring metal. Because it is 75% gold and 15% alloy, it is stronger than 24K gold, and won’t bend or wear away as quickly. Yet, since it’ is gold, it is easy to polish and repair and won’t tarnish. It is also available in a variety of colors including stylish white and classic yellow. 18K gold is at once durable, precious, and affordable.
14K GOLD
14K gold is 10/24 alloy and is thus strong and reliable. However, it retains the visually soft and lustrous appearance of higher content gold. It will resist wear and tear, and will sparkle for years to come. 14K gold is also available in a variety of colors and is a setting option that is both durable and affordable.
Sterling Silver
Sterling Silver is the standard for high-quality silver jewelry. It is an alloy that is 92.5 percent silver and 7.5 percent copper. The addition of copper is to ensure the metal’s sturdiness, as silver is very soft, and does not diminish the value of a piece. Rather, silver jewelry is priced according to the complexity of design and the amount of labor necessary. It is highly reflective and versatile and is commonly used for designer jewelry. Silver is beautiful and long lasting.
