Diamonds And Precious Gems

A more in depth answer can be found at How do You Read An ASET Diamond Image Q: hi, I want to buy a diamond and have been looking at diamonds online and am wondering if you could shed some light on the images that are red and green. I see that they are labeled ASET, but I don't know what that means? Do you have anything on the topic? I know I can search online but I figured it would be better to ask someone that knows about diamonds. I like your way of explaining things very simply.

Clarity is an important characteristic of a diamond if it is to be used in jewelry, particularly in an engagement ring , and it is important to know the clarity of a diamond before you buy one. Understanding what clarity means will give you an idea of how it affects the look of a diamond. It is actually quite easy.  We can divide this up into two categories: 1 Diamonds with visual inclusions and blemishes, 2 Diamonds that are ‘eye clean’ meaning that there are no inclusions or blemishes that can be seen with the naked eye. From there, the clarity of a diamond is further broken down into subcategories. Many people mistakenly think that diamond clarity refers to how clear it is. This isn’t so. Clarity actually refers to the internal and external imperfections of the diamond. The best diamonds, of course get a grade of FL or IF – Flawless or Internally Flawless – meaning that it is perfect. A grade of I-1, I-2 or I-3 means that the diamond has inclusions,  w...
