You need to know how to choose a loose diamond, but you are not sure where to start. Two diamonds that look almost the same to you may be a couple thousand dollars apart in price. All you know is that carats are good and you want a lot of them, but beyond that you are stumped.The first thing you must do when you want to know how to select discount loose diamonds is to learn the famed “four C’s”: cut, color, clarity, and carat. They are the four most important parts of any diamond and will go the farthest in determining the value of a diamond. Let us consider them in turn.

Cut

When you are choosing a loose diamond, the most difficult trait to quantify is cut. This is the manner in which the diamond is shaped, its symmetry, and the way that it looks under light.

A properly cut diamond will reflect and refract incoming light through its facets, creating sparkle. Unfortunately, cutting a diamond also removes carat weight, so many borderline diamonds will not be cut ideally.

In the most general sense, the more facets a diamond has, the more it sparkles. However, this is not absolutely true and should not be considered a hard and fast rule.

Color

Diamonds come in all colors of the rainbow. Blue, green, orange, yellow, whatever you like. Some colors are rarer than others, with completely colorless diamonds being the rarest and most valuable of them all. Some so-called “colorless” diamonds actually have a very slight yellow tint, though it will be all but invisible to anyone other than a trained professional.

Diamonds are graded on their lack of color, as the clearer they are, the more sparkle and fire they show. Thus, the less color a diamond has, the more valuable it is.

Colors are generally graded on the scale instituted by the Gemological Institute of America. The scale ranges from D-Z with D being absolutely colorless.

Any diamond with a color other than clear are said to have “fancy colors”.

Clarity

Clarity is affected by flaws or blemishes inside the diamond and identifying marks inside the diamond or on its surface. Flawless diamonds are exceptionally rare. However, a few imperfections within the crystal can help identify a diamond and prevent fraud.

Inclusions and blemishes will affect the value of a diamond, particularly if they cause the diamond to be murky or if they are visible to the naked eye. Inclusions are caused by foreign substances that were in the way when the diamond was formed. Blemishes are caused by the intense stress placed on the diamond by the cutting process. Cracks, chips, and nicks caused by the cutting process will affect the price even more, as they are errors in cutting that should have been avoided.

Carat

The most commonly considered trait of a diamond is the number of carats. The carat is a unit of weight equal to 200 milligrams. Carat can also be expressed in the number of “points”. For instance, a 1.25-carat diamond will have 125 points.

If you are thinking about a diamond, just remember that more carats are better. It is simply a unit of weight and, therefore, the size of the diamond.

Also, when you want to know how to select discount loose diamonds, don’t forget that these are not the only considerations. You should also see a rapaport sheet on any diamond you are considering. It is a 鑽石等級 report that should come with any diamond. These reports grade the diamond according to strict guidelines and prevent fraud. So take a look at the rapaport sheet that comes with any diamond before you buy.
