Surprising your girlfriend with a beautiful diamond ring is a moment both of you will cherish your entire life. A once in a lifetime occasion, buying a diamond ring should be done carefully as your fiancée will wear it everyday, showing it off to her friends and family members, flaunting your love.

The market is flooded with numerous jewelers and shops claiming to sell the most authentic and beautiful diamonds there are. To make the right choice from the plethora of designs and variety can indeed be a confusing task. It would do you good to be aware of some basic tips on buying diamond jewelry before you buy one for your girlfriend. The ‘four c’s’, color, cut, clarity and carat, are the deciding factors for a diamond’s purity and value. This king of gems comes in all colors, with white being the purest and costliest. Although it is the hardest stone available, diamond can be cut in a variety of fancy shapes and sizes. The shape and cut determines the shine of the gem.

One should choose the shape of the diamond according to your girlfriend’s personality. If she is dainty-- buy a small elegant one; tall and well-buily? go for a large squarish rock. The sparkle of the diamond often holds more importance than the rock’s size. Clarity of the diamond ensures a dazzling shine every time the light passes through the stone. Carat, or the weight of diamond, also contributes to its price and value in the market.

Educating yourself about the ‘four c’s’ will keep you from buying imitations. Even though it is conventional to spend two months salary on your engagement ring, you can buy synthetic diamonds, which will be easier on your wallet. Synthetic diamond has the same physical properties of a real diamond but is more affordable than the real one. Finally, do ask the jeweler to provide a purity certificate, which will serve as a guarantee and later help in insuring your gems.
