Diamond Grading

At Diamond Brother’s, we adhere to the Gemological Institute of America’s (GIA) International Diamond Grading System when purchasing and when selling diamonds. The GIA standards are also used for appraisals. The 4 C’s of Diamond Grading Each diamond is one of kind so no two diamonds are the same. The 4C’s of Diamond Grading, which include Cut, Color, Clarity, and Carat help identify and determine the value of your stone. When shopping for a diamond, you should first have an understanding of the 4 C’s so you can better understand their value and relative importance to you.

  1. Cut – GIA refers to cut as the ratios of height, width and depth of the diamond as well as the size of the table – the horizontal facet on the flat of the diamond. An ideal cut diamond reflects the most light back out, enhancing its overall sparkle.
  2. Color – When it comes to diamonds, the less color the higher the grade. The scale ranges from D-colorless to Z-light yellow or brown. Colored diamonds (such as pink, Canary or chocolate diamonds) are graded on a separate scale and can be as valuable or more valuable than colorless diamonds.
  3. Clarity – Diamonds are assigned a grade based on the number of inclusions. A flawless diamond has no inclusions under 10x magnification, making them very rare and valuable. The grading continues to Internally Flawless, Very Very Slightly Included, Very Slightly Included, Slightly Included, and finally Included. Many inclusions cannot be seen with the naked eye.
  4. Carat – The size of diamonds is measured in carats. A one carat diamond is substantially more rare than .50 carat diamonds. Because of their uniqueness, one carat and larger diamonds are more valuable.
