VS1 + VS2
VS1 and VS2 diamonds are two grades of clarity standing for Very Slightly included 1 and 2. This clarity grade is given to stones that have very few inclusions visible to the eye, or even to the eye using 10x magnification, or a jewelers loupe. VS1 and VS2 stones usually have inclusions but during the cutting and polishing process they have been strategically placed so that they do not affect the aesthetic of the stone, or the inclusions themselves are light in color and look like small feathers or pinpoints. When you see the certificate of a VS1 or VS2 stone, you may be able to take a look at the image of the stone identifying exactly where its inclusions are located and how it may affect the clarity of the stone.
SI1 and SI2 are the next two grades down from the VS’s we just spoke about. SI meaning slightly included, these stones tend to have more inclusions than VS stones, which are either darker in color or more noticeable due to their placement. The difference between the look of an SI1 and an SI2 stone can be noticeable, so again, it is always good to take a look with a loupe and read the diamond certification. SI1 and SI2 stones are usually great value for your money and though they contain inclusions, are still considered a good diamond clarity, SI1 is obviously just a bit better than SI2.
When shopping for your diamonds, take a look at one of each to see the differences in price, the number and type of inclusions and see which looks best to you. All the above clarity grades are considered good, but remember someone else has given them that grade! Take a look for yourself and see which stone looks the best clarity-wise to you. Each stone is different and the inclusions in the end are what make your stone so special!
