To discuss how clarity grade in a diamond affects the diamond's value, we contrast and compare several of the world's diamonds measuring agencies. Of these we will compare other systems most particularly with the GIA, or Gemological Institute of America. You will find that the very top ratings for diamonds allows for and is limited to flawless diamonds to a power of ten magnification, using the small hand held jewelers tool, the loupe. So even if a greater magnification than ten may show microscopic flaws in the diamond, so for the sake of precision these top diamonds flawless to the power of ten.
Designations in the GIA are, from the top, FL or flawless, and IF in the second half of flawless. Next, IV is in the second tier of diamonds that are still yet flawless to the power of ten. Next categories in descending brilliance and value, are VVS1, VVS2,VS1, VS2, SI1, SI2, I1,I2, and I2, at the lowest value and quality. The top tier diamonds are one category divided into two in the SCAN, the Scandinavian system and in the American created GIA system. On the GIA scale FL is the grade that was designated flawless to the power of ten magnification. IF is the designation of the top and best diamonds in the GIA system.
IF diamonds or gemstones have no internal flaws and only a small amount of minor external blemishes that can be removed by pooishing such as nicks and scrapes, small pits. IF diamonds are rare when they are also colorless and well proportioned. This is what puts them ahead of lesser diamonds, with increasing numbers of flaws and blemishes. VVS1 and VVS2 are grades given to diamonds with flaws so minor inside that only the expert eye can detect them. VS1 and VS2 are the diamonds with very small flaws and inlusions, which are inner flaws. SI1 and SI2 are diamonds with flaws apparent enough that a non expert would be able to discern.
This would be done with the aid of a loupe, a small hand held magnifying glass held up to the eye. The viewer then holds the diamond up closely and turns it slowly all around. There are more diamonds with flaws than diamonds that are flawless, hence the increased price with the flawless diamonds. These grades are still sought after and as they usually cannot be seen by the eye when mounted, they are gaining in popularity. This enables one on a limited budget to get more diamond in higher color, or in a larger size.
The imperfect grades are given to diamonds that a qualified gemologist or jeweleer would be able to detect with the aid of a loupe.
They are graded I1, I2, and I3, or first pique, second pique, and third pique. If they are lively and brilliant, some diamonds from these classifications may be a bargain price. However, while you get a bargain on having in your possession a nearly flawless diamond at a low price, you may find the same reasons make unlikely for a good price on the resale, if you ever choose to sell. You should be clear in the understanding that each diamond falls within a range within its category, some bordering the higher, and some the lower grade. This will affect the cost.As example a VV1 diamond may be on the high end of its range and closer to being rated the higher VVS2.
If however the diamond is on the lower end of its valuation grade, it would be closer to a VS2 or even a SS1. If you are considering owning a diamond, be aware that some I1 diamonds are now machine made, and therefore not suitable for personal wear. Make sure you purchase from where you are confident in the company that guarantees satisfaction for your purchase. Shop around and browse before you make yup your mind, the thrill of possessing a diamond can be worth the effort. Ownership of a diamond is rrewrding in itself, let alone the opportunity for profit. Enjoy.
