As with the traditional wedding band, an unbroken circle symbolizes lasting love and commitment. Finding the perfect ring to represent such an important and meaningful occasion should be a fun undertaking, and most brides know when they've found just the perfect one.

Solitaire diamonds set in platinum or gold are without a doubt today's most popular choices. Many brides-to-be are also choosing one of a kind antique and estate rings as well as rubies and sapphires with baguettes or side stones as their engagement ring.

Wedding bands and engagement rings are often sold in sets so that rings fit together and the bride and groom's rings match. While there are an endless variety of styles and individual preferences, the rules governing the selection of a quality diamond are pretty much set in stone. A reputable jeweler can provide you with the best information. Plan to visit several jewelers to find a professional you can trust and one who can work with you to find the best quality within your budget.

Look for jewelers with credentials. Two of the most respected and prestigious associations are the Gemological Institute of America (GIA) and the American Gem Society (AGS). Educate yourself as to what makes a particular diamond valuable before you buy.

The four C's -- Cut, Clarity, Color and Carat -- are the factors commonly used to determine the quality and value of a diamond. A fifth C -- Certification -- has been added to the list recently. While most jewelers routinely provide you with a written guarantee and registration of your diamond, taking your diamond to an independent appraiser for their rating is a good idea.

With a little knowledge and your personal taste in mind, you are sure to find shopping for this most precious of personal possessions a once in a lifetime pleasure. Keep in mind that a diamond, like your upcoming marriage, is forever.
