As the diamond industry has evolved, so too have the quality features we use to help benchmark a diamond’s quality. Some other critical factors to consider when purchasing a diamond are:
There are many diamond grading laboratories around the world that offer varying degrees of diamond identification and grading services. At Tok Jewellers, we recommend purchasing diamonds that are accompanied by an independent grading report from the GIA (Gemmological Institute of America) for added peace of mind. GIA is the world leader in diamond research, grading and consistency with their processes. They are the most highly regarded laboratory around the world by the diamond industry. Other reputable diamond grading laboratories include AGS, GSL, IGI, HRD and DCLA.
Diamond fluorescence is a fascinating, natural phenomenon where diamonds glow when exposed to UV light. This is where our extensive knowledge and supplier network can assess the diamond by hand and determine if the fluorescence is positive or negative, thus ensuring that you make a worthy purchase. The presence of fluoresce can significantly affect a diamonds price, especially if the reaction is negative. At Tok Jewellers, we recommend that if a diamond has a Medium, Strong or Very Strong fluorescence grade, it should be inspected before purchasing to ensure that the fluorescence is positive. Diamonds with no or faint fluorescence can be purchased without hesitation, provided all other quality factors are ideal.
Along with the overall cut-grade of a diamond, it is also very important to ensure that a diamonds final polish and facet arrangement (symmetry) are of high standards. If the diamond does not have a high polish and has lop-sided facets, it results in the diamond looking dull and can cause dark spots on the surface of the diamond, which makes them look very unappealing and reduces their light performance. Polish and Symmetry are graded as being from EXCELLENT, VERY GOOD, GOOD, FAIR or POOR. At Tok Jewellers, we stock and sell GIA-certified diamonds with polish and symmetry grades of EXCELLENT and VERY GOOD as they represent the best quality diamonds.
