Clarity
She’s one-of-a-kind. And her diamond will be, too.
Diamonds are like snowflakes — each one is unique. That’s because during crystallization, minerals can get trapped in the diamond. These characteristics, sometimes called inclusions, or blemishes, give each diamond its individuality. Some people also call them "birthmarks." The number, color, size, and position of these all affect our assessment of clarity.
Size: How large the inclusion is.
Number: How many inclusions are present.
Position: Where the inclusion is located. For instance, it may be more hidden in the inside lower facets, or more obvious on the surface of the diamond.
Nature: Based on their size and location some inclusions may affect the durability of the diamond.
Relief: Based on color, some inclusions may be more apparent than others. For example black inclusions are much more visible than white or clear inclusions.

The Gemological Institute of America (GIA) has a scale to measure diamond clarity, ranging from FL, which means "flawless," to I3, which means obvious inclusions and blemishes are visible. Subscript numerals indicate the variations within each grade, with 1 indicating higher clarity, and 3 indicating less clarity.
Let’s be clear.
Most inclusions aren’t visible to the naked eye. So when you’re looking at different diamonds, you might decide to give a little on clarity so you can afford a better cut — or a larger size. That, of course, is a matter of personal taste. Because at the end of the day, you want the diamond that looks the most beautiful to you — and to her!
