Clarity

General Information

A flawless diamond is said to have zero or almost impossible to see inclusions within its physical composition. Clarity is graded on the number of inclusions, frequency, size and locations. The fewer in number these imperfections are, the greater the value of the diamond and the “cleaner” a diamond appears to the eye or loop.

Almost all diamonds have natural characteristics, or inclusions unique to the particular stone. Some are obvious at a glance, some are undetectable with the naked eye. Inclusions affect a diamonds ability to refract light, thus determining the overall brilliance. The fewer the inclusions, the more valuable the stone.

Flawless diamonds are rare, and are usually found in crowned collections. Diamonds with very, very small (VVS) or very small (VS) inclusions are highly valued and are closer to the top of the diamonds scale. Diamonds graded I1-I3 has inclusions that can be seen by the untrained eye.

Practical Views

Clarity of a diamond is the easiest of all the five C’s. We personally like any diamond were we cannot see any inclusions. We try to keep people between VS2 and VVS1 clarity. You can purchase a flawless diamond but the sparkle will not increase. The only difference is under 10X. The flawless diamond will have fewer inclusions if any, than the VVS1.
