They say that diamonds are a girl’s best friend, so diamond necklaces must be the best friend that lasts forever.

Diamond necklaces are one fashion accessory that can be worn with virtually any outfit. Depending on the size and the style of the necklace it can dress up a casual outfit of jeans or a sweater or it can be the finishing touch to an elegant gown.

Diamond necklaces come in many different designs and the most difficult part in choosing one can be deciding which one best suits your personality.

One of the first considerations when purchasing a diamond necklace is the size of the diamond. Diamonds are measured in carats with a larger number indicating a larger and more expensive stone.

Some diamond necklaces contain a single stone while others have a collection of smaller stones. In the case of the necklace with several smaller stones the diamonds weight are added together to give you a total carat weight for the necklace.

Although it’s important to consider the size when purchasing diamond necklaces it’s also advisable to take other characteristics of the diamond into account.

All diamonds are judged on their color. If you briefly glance at a diamond you might consider that they are all a brilliant clear color. This isn’t true.

There are diamond necklaces that cover a full range of hues. Diamonds are placed in several different color categories. Colorless and white are two of them. These types of diamonds when placed in diamond necklaces are considered the purest form of diamond.

Other colors of diamonds include blue, yellow, orange, pink, brown, green and red. If a diamond has a hint of any of these colors it is considered to be impure. They are stunning though and make a wonderful additional to diamond necklaces.
