The 4 Cs and 3 Others

Perhaps the most well known characteristics of diamonds (aside from their toughness) are the “4Cs”. These are:

• Cut
• Clarity
• Colour
• Carat

I also believe that there are three other Cs which could be added.
These are:

• Certification (from independent gemmological laboratory)
• Choice (of merchant)
• Conflict (diamonds)

The following sections will give a thorough explanation of each of the Cs.
