Diamond clarity is graded under standard viewing conditions with 10x magnification. The grader carefully examines the diamond in order to identify internal clarity and surface characteristics. Tiny crystals and other features enclosed in the diamond when it formed are called inclusions. Surface features on the outside of the gem are called blemishes. Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone.
While no diamond is perfectly pure, the closer it comes, the higher its value. Diamonds with no internal inclusions visible at 10x magnification are Internally Flawless. Diamonds that are graded VVS1 have a minute inclusion or two that range from extremely difficult to very difficult to see for a skilled grader using 10x magnification. The inclusions in a VVS1 diamond are likely to be pinpoints, clouds or needles.
And why not settle with the second best if it will give her the same wow and the maximum value for your money? The flaws in this grade are so slight that even an expert can find it difficult to view imperfections in 10x magnification. VVS1 diamonds have superb sparkle because of their very minute impurities. This makes the light that enters the gem almost totally unbarred!
The kinds of inclusions experts see or sometimes have a hard time seeing are clouds, pinpoints, and needles. Before we delve in further…. However, this is what experts use to detect flaws and according to the amount of impurities, they assign a respective clarity grade. The bigger in size and amount the inclusions are, the lower its grading. Diamonds are labeled from Flawless to the lowest level of Included. This picture below gives a good depiction of the different clarity grades:.
Take note that no two diamonds are alike. Inclusions may also vary in position and reflectivity that greatly affects the quality of the gem. And even then they will be hard to see. VVS diamonds are all eye-clean. Inclusions are easier to spot in step cut diamonds, and the bigger the diamond the more visible the inclusions will be.
Again, the bigger the diamond the more visible the inclusions. While a 3 carat VS2 round brilliant can be eye-clean, it also might not be. Buying a diamond is part art, part science.
Going with an internally flawless diamond makes quite the statement. Not really. VVS is a measure of clarity, not sparkle. While inclusions can impact sparkle if they obstruct the light, this really only occurs in very low clarity diamonds with very large inclusions.
The inclusion s is barely visible under magnification and requires very extensive training to identify under magnification. The inclusion is literally microscopic. The most common inclusions for VVS1 are pinpoint, feather or natural. The inclusions are typically only viewable from the bottom or pavilion of the diamond. No imperfections can be identified by the naked eye.
In summary, the only material difference is price.
