About the GIA Diamond Grading Laboratory

One of the most widely recognised independent diamond grading laboratories in the world, the GIA (Gemological Institute of America) created the international diamond grading system we use today to value diamonds - the 4Cs.

Grading laboratories, such as the GIA, exist to provide peace of mind by creating standards used to grade loose diamonds.

Diamonds 27 sells GIA certified diamonds and adheres to strict standards associated with diamond grading. Buy GIA Certified diamonds at exceptional value at http://www.diamonds27.com/
