Cellini sorts, selects, and ships, only the highest quality diamonds, selecting the top four colour grades (D-G) and the top three clarity grades (IF, VVS, & VS), and most importantly, accepts only the highest standard of cutting.

The linked guide will help anyone to understand diamonds and how they are graded. Diamonds are the only gemstone that has a universal grading system which enables comparison by the purchaser. However as general advice; if you want a diamond to really sparkle, always focus on quality.

If you would like to understand diamond grading, certification, or Cellini's diamond policy please follow the links below.
