All rather confusing, isn't it. To cut to the quick, if you want something that for most people will look colorless or white, you're probably best buying something higher that I on the color grading scale. On the other hand, recently diamonds in the various Cape grading ranges have become quite popular as fashion jewelry, being marketed with such names as champagne diamonds or cognac diamonds. If you would like some more perspectives to help you make a buying decision, see the discussion on which diamond to buy, found elsewhere in Cyberspace. Clarity Clarity refers to how free of inclusions the diamond is.
Most diamonds have small inclusions, usually small spots of carbon.
These are often called flaws, but there are other types of flaws as well, such as fractures. Inclusions that are so small as to not be seen under 10 power magnification are considered to not exist when it comes to grading. Just as with the letter grading scale for color, there is also a letter grading scale for clarity. No inclusions visible under 10 power magnification. Extremely small inclusions that under 10 power magnification are visible, but are very hard to find.
