With so many choices, how do you choose the metal for your wedding rings? Here are some fun facts about each metal:

Gold: Gold is a rare element, and has been used throughout history as currency, jewelry, decorative objects, and more. It has spawned wars and launched voyages. It is extremely durable and malleable. One ounce of gold can be pounded into a 187 square foot sheet or stretched into a wire 40 miles long. Pure gold is 24 karat, although you will more often see it alloyed with other metals to bring it to 18 karat or 14 karat. Its bright yellow color is loved for being rich and beautiful.

White Gold: White gold is gold that has been alloyed with nickel or palladium, then plated with rhodium to give it a cool, white tone. Rhodium is extremely hard and bright, and is actually one of the most expensive precious metals. Over time, rhodium may need to be reapplied to maintain its white finish.

Platinum: Platinum is the strongest and rarest of the precious metals. It is naturally white, and platinum jewelry is typically 95% pure, making it a good choice for those who have sensitive skin or an allergy to nickel. Platinum is a dense metal, and jewelry made from it will be more expensive than gold. Platinum is also used in the medical field for pacemakers, and in the automotive industry for catalytic converters.
