Gold
Gold has been the inspiration for jewelry since the beginning of time. It's coveted for its gleaming beauty and strong yet malleable nature. Gold will not rust, corrode or tarnish.
Gold is measured in karats, abbreviated as the letter "K" and preceded by a number. 100% pure gold is 24K. However, in its pure form, gold is too soft to be used in jewelry. In order to give it resilience to hold up to everyday wear, gold is alloyed with other metals.

14 karat (58.3% gold)
Great for use in traditional jewelry. This is a hard, resilient metal that will maintain much of its original look (polish and detail) for many years.

18 karat (75% gold)
Excellent for use in fine jewelry with a rich, deep color. 18K gold is a little softer than 14K and will usually wear a little more, giving it a soft patina.

Platinum
Platinum is pure, an expression of integrity, a reflection of inner truth. Platinum's purity endows it with a brilliant white luster. This helps to reflect the true radiance of diamonds. Because it is generally 95% pure, platinum jewelry does not fade or tarnish and keeps its looks for a lifetime. Platinum's purity makes it hypoallergenic and ideal for those with sensitive skin.
Platinum jewelry is the perfect choice for a lifetime of everyday wear. Its density and weight make it more durable than other jewelry metals. Platinum does not wear away and holds precious stones firmly and securely. Like all precious metals, platinum scratches. However, the scratch on a platinum piece is merely a displacement of the metal and none of its volume is lost. 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.
