Important Details When Purchasing a Diamond

A diamond has long been revered as the ultimate symbol of lasting love because of it's purity and ageless beauty.

Whether you have experienced buying diamonds for engagement rings before or not, you may be unsure as to why one is worth $3000 while another one is only worth $300. What goes into determining the price of a diamond?

The physical weight of a diamond is referred to as its "carat". The value of a diamond is directly proportional to its size. The larger the diamond, the more valuable it is, because larger diamonds are less common. Greater size makes the diamond more spectacular, and therefore increases the purchase price.

After carat weight is obtained, the next aspect that can cause price deviation is the clarity. You can determine the clarity of a particular diamond by a number of features. The term inclusions refers to imperfections inside the diamond, while blemishes refer to imperfections on the surface.

The quantity, type, location, measurement, and tint of its inclusions, or internal facets, as well as its blemishes, or features on the surface, all factor into the clarity. The clarity ranges from the rank of 'pure,' meaning no flaws, to 'heavily included,' meaning that it is seriously damaged.

These differences are due to the cooling process of the diamonds against other materials. Lack of clarity is a lack of perfection. A diamond is forever, and no one wants to be stuck with an imperfect one forever; therefore, this impacts the price.

Color is the next factor that determines a diamond's overall value. If possible, a diamond should be as clear as water, but this is not always the case. Colors from other gases and minerals around during the time of the diamond's formation may have altered its clean appearance and left the gem tinted.

Diamonds range in color from a designation of "D" to "Z", with "D" being no color at all, and "Z" being a diamond with a color that is deep enough to be very noticeable to the human eye.

Cut is the final factor in diamond grading. This is an often forgotten element of diamonds, but it is extremely important, as it gives this remarkable stone its ability to come alive.

A diamond that sparkles and glitters can be said to have 'fire'. The actual rating system uses common words like good, average, and irregular. The bottom line though is if you want your diamond to sparkle even in dim light, then you need to make sure the cut is impeccable, and that will cost you more money.

So there you have it, the 4 C's of choosing a diamond: carat, clarity, color and cut. Understanding these basic concepts before you enter a diamond store will go a long way towards making an outstanding buying decision.
