IGL Laboratories is a well-respected diamond grading laboratory. IGL has been acclaimed as an innovator in the diamond grading industry due to our continuous research and our development of the first scientific system used to evaluate how well a diamond has been cut. IGL Laboratories are respected by diamond manufacturers, jewelry retailers and consumers alike for our accuracy and consistency in every aspect of diamond grading.
It is essential for each diamond proprietor to know the credentials of their diamond in order to obtain confidence and assurance of the integrity of what they have acquired. An IGL Diamond or Gemstone Certificate is a statement issued by one of our independent gemological laboratories documenting the characteristics of the stone as determined by our experienced diamond graders at the time of evaluation.
A diamond's value is based on four main characteristics known as the "4 Cs". Clarity, color and cut (proportion) together with the carat weight determine the value of a stone.
Hearts and Arrows Diamonds are precision cut variations of the traditional 57 faceted round brilliant cut. They are cut to “ideal proportions” with superior optical symmetry and a specific faceting pattern. When all these factors are in harmony the result is a repeatable, near perfect pattern of eight symmetrical arrows in the face up position and eight symmetrical hearts when viewed in the table down position.
