Below are some useful explanations of basic diamond information known as the Four C’s.
A diamond’s weight is measured by carats. Generally, the size of the diamond is proportional to the weight of the diamond. While the carat size is the easiest aspect of diamond buying to understand, it alone does not set the value of the stone. Before running out and buying a huge diamond, first consider the other 3 C’s. Smaller diamonds with better clarity and color could hold more value than larger, less perfect stones.
Some exotic diamonds can be found in pinks, blues, greens, or canary colors. The most common diamonds, however, generally range in color from colorless to yellow. Absence of color marks the purest diamond. We suggest that you determine the color grade that best fits into your budget when compiled with the other three C’s.
A “G”,”H”, or “I” diamond is not colorless, however they will appear pure when set in a ring. Also, consider using a platinum setting because it will make the diamond appear more pure.
There are several aspects to consider when looking at the cut of a diamond. First, diamonds can be cut into a variety of shapes. Cut also refers to the proportional nature of the cut. A well cut diamond will be proportional in terms of size (the top, or table of the diamond) and depth (the cone of the diamond) and the cuts will be symmetrical. When a diamond is cut well, it will reflect the light better and appear to sparkle more.
Below are a few charts which can assist you in determining quality of cuts.
- Very good cut: Represents roughly the top 15% of diamond quality based on cut. Reflects nearly as much light as the ideal cut, but for a lower price.
- Good cut: Represents roughly the top 25% of diamond quality based on cut. Reflects most light that enters. Much less expensive than a very good cut.
- Fair cut:Represents roughly the top 35% of diamond quality based on cut. Still a quality diamond, but a fair cut will not be as brilliant as a good cut.
Clarity refers to the lack of imperfections, or inclusions, in the stone. A diamond that has an inclusion that can only be seen at 70X magnification holds a hefty price. Again, consider the other three C’s when making your own diamond selection. An inclusion that can be seen at 10X magnification is much cheaper, and will not be visible to the naked eye. Inclusions do interfere with the way light passes through a diamond. Therefore, a diamond with more inclusions will not sparkle like a diamond with very little inclusions.
