The 4 Cs of a Diamond

Below we explain the 4 C’s of a diamond and why they are important to know before you buy a diamond.

CARAT

A diamonds cut is casually used to describe its shape which isn’t correct.

A diamond’s cut in actuality is used to describe the stones interaction with light and the ability with which light penetrates and reflects off of it – this is also known as the stones “cut grade”. 

A diamonds cut grade depends largely on the proportions of the facets and diamond itself – a diamonds cut can be too long or shallow, both of which have a negative effect on the cut grade.

COLOR

Yes, diamonds do have color. From bright to yellow.

When it comes to diamonds, the ideal color is no color – that is, a colorless diamond is the most valuable diamond. The color of a diamond is carefully determined in a controlled environment with carefully controlled lighting and specific conditions for viewing conditions.

A diamonds “color” ranges from D through Z, with a “D” grade color being completely colorless and a “Z” grade color being saturated with a yellow tint. As the alphabetical letters progress, the differences from the first to the next are subtle to the untrained eye – that is, an “E” grade diamond  might not appear to be different from an “F” grade diamond to the untrained eye, but they might vary highly in price.

CLARITY

All diamonds naturally have inclusions or blemishes inside them.

The clarity of a diamond is defined as its absence of blemishes and inclusions. A blemish, in terms of diamonds, is an external defect, while an inclusion is internal. Diamond clarity is examined under 10x magnification and is rated as follows in the picture below. 

If you’re in the market for the best of the best, an FL diamond is your best bet. If, however, you’re looking to skim a few bucks, we recommend an “eye-clean” diamond which may have internal inclusions, but they are not visible to the untrained and unaided eye.

 

CUT

A diamond’s cut grade is the most important element of the 4C’s and the highest indication of the diamonds value.

A diamonds cut is casually used to describe its shape which isn’t correct. A diamond’s cut in actuality is used to describe the stones interaction with light and the ability with which light penetrates and reflects off of it – this is also known as the stones “cut grade”. 

A diamonds cut grade depends largely on the proportions of the facets and diamond itself – a diamonds cut can be too long or shallow, both of which have a negative effect on the cut grade. A diamonds cut grade also depends on the cuts influence over the brightness, fire and scintillation of the diamond. A diamonds brightness is the extent with which is takes light in and reflects it out, its fire is the rate with which the light taken in is scattered into a rainbow effect and the scintillation is the diamond’s sparkle and the shadows and light created within the diamond by reflections.
