Clarity in a diamond, we have all heard about it, but what does that really mean when one looks at a diamond or diamond ring? What do I see in real life? How beautiful is a diamond with a certain clarity?
Clarity is a value based upon inclusions. Inclusions are natural flaws in a diamond (or gemstone). Formed in the earth, most all gemstones have large, small or minute variations inside them. These irregularities are desirable and prove that the material is indeed natural and made by nature. However, some variations can affect a diamond’s beauty or brilliance.
For a start, let’s review how diamond clarity is graded. It begins with the famous F or flawless and moves down the scale from there. Most diamonds one will find for sale or set into jewelry are graded in the ranges below:
You probably didn’t realize that you cannot see with the naked eye any inclusions or flaw of most all the grades listed above, from an SI1 or better. In fact, some diamond inclusions you cannot even see if above an SI2.
Diamond inclusions come in many types but have two basic divisions, those that are dark, and those that are clear. If the inclusions are clear, and the grading is above an SI2, good luck finding them with your eyes! In most all cases, you don’t see a thing. Using a microscope or a jeweler’s loupe (magnifying glass for jewelers) reveals those inclusions in the finer ranges.
Price is strongly effected by clarity certainly. But did you know that antique diamonds most commonly fall within the VS2 and lower range? Surprising that a majority of the grades listed above are rarely found among antique diamonds such as the old European or old mine cut. When choosing a diamond ring or engagement ring, it is helpful to know before making your final choice.
