Have your ever wanted to know about the Four Cs of diamonds? Here is some information that will explain the Four Cs to you so that your diamond purchases will be easier and convenient.

The four Cs of diamonds are Clarity, Color, Cut, and Carat. Lets go over the basics of each one, starting with Clarity. Diamonds are formed in the Earth and they contain “birthmarks.” These birthmarks can be internal and/or external and they affect the Clarity grade of the diamond. The diamond clarity scale was created by the Gem Institute of America (GIA), the gold standard of diamond grading.

Here is an excerpt from the Gem Institute of America:

The GIA Clarity Scale contains 11 grades, with most diamonds falling into the VS (very slightly included) or SI (slightly included) categories. In determining a clarity grade, the GIA system considers the size, nature, position, color or relief, and quantity of clarity characteristics visible under 10× magnification.

Flawless (FL) – No inclusions or blemishes are visible to a skilled grader using 10× magnification
Internally Flawless (IF) – No inclusions and only blemishes are visible to a skilled grader using 10× magnification
Very, Very Slightly Included (VVS1 and VVS2) – Inclusions are difficult for a skilled grader to see under 10× magnification
Very Slightly Included (VS1 and VS2) – Inclusions are minor and range from difficult to somewhat easy for a skilled grader to see under 10x magnification
Slightly Included (SI1 and SI2) – Inclusions are noticeable to a skilled grader under 10x magnification
Included (I1, I2, and I3) – Inclusions are obvious under 10× magnification and may affect transparency and brilliance
At the Spexton Fine Jewelry store on Cherry Street in Tulsa, Oklahoma, our staff will help you find just the right diamond. One of the co-owners of the store, Andy Marcum, has almost forty years of experience in the diamond industry and he can help you obtain the best diamond possible for your taste and budget. At Spexton Fine Jewelry, we allow you to log-in to our diamond trading network to see all of the diamonds on the market. Once we find a diamond that fits your perimeters, we have the diamond shipped for you to see it in person (with no obligation to buy). You can view the diamond under 10x magnification to see the clarity characteristics.

We show you the invoice of what we pay for the diamond and charge just ten percent on top of that. For example, if we pay $5,000 for the diamond, you pay just $5,500 (plus sales tax). It is that simple.
