Diamond Sofa

GSI graded a number of the diamonds larger than the GIA and a few lower, making it onerous to find out the consistency of a GSI grading. When in search of a diamond, it’s critical to chose a diamond licensed by a reliable, consistent entity, just like the GIA, so you realize that what you might be buying matches the actual value of the stone. To show how GSI grades diamonds in comparison with other labs, we sent four stones to GSI, IGI, HRD, EGL and GIA.
