Clarity Grade

It’s all about what you can’t see

By the nature of their formation in the earth, most diamonds contain unique imperfections called inclusions. Diamonds with very few inclusions are rare and, of course, rarity affects a diamond’s value. Using a grading system, diamonds are given a clarity grade that ranges from flawless (FL) to prominent inclusions (I2). Every diamond is unique, but none are absolutely perfect. In determining a clarity grade, diamond graders consider the size, nature, position, colour, and quantity of clarity characteristics visible under 10x magnification.

Common Mistake

Often a first time buyer will mistaken the word clarity for a diamond’s sparkle and radiance. These elements are determined by the diamond’s cut.

Global Diamonds’ Tip:

In general, any diamond with a clarity grade of I1-I3, has inclusions visible to the naked eye. Global diamonds recommends avoiding diamonds in this scale, and advises to purchase in the SI2 grade or higher.

However further to this, a flawless diamond is not necessarily any more beautiful to the eye than an SI2.  For this reason, clarity is a grade you can keep down in the SI grades putting your budget towards other elements of the diamond such as better colour or cut.

Also note that grading for clarity is a subjective matter.  We see many diamonds that say they are SI2, but on inspection they actually look more like I1 grade.  This is where it is important to know that the seller of the diamond actually has the diamond in hand, or is willing to get it in from offshore, without any down payments.  You don’t want to end up with a diamond with inclusions that are visible to the naked eye.
