What is Diamond Grading?
Diamond grading is the process used to evaluate the true characteristics and therefore the true value of a diamond. IGL’s diamond gradin process is well known for our unique eight-step process.
Why is Diamond Grading Important?
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.
What are the "4 c’s"?
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.
What are hearts and arrows?
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.
