                                                  Are ‘Post-Growth Treatments’ Permanent?

                                                  As lab grown diamonds gain popularity consumers have questions about the "post-growth treatment" comment seen on many IGI grading reports. Post-growth treatments are commonly used to reduce, eliminate or change the diamond's color-appearance. Logically, people want to know "are the treatments permanent?"

                                                  Inclusions Seen in Lab Grown Diamonds

                                                  There are two sophisticated ways of producing lab-grown diamonds. One process assembles the diamond in vertical layers and the other uses a metal catalyst to dissolve carbon. These different approaches produce inclusions which differ from those seen in natural diamonds.

                                                  IGI Now Issuing Cut Grade for Fancy Shapes

                                                  IGI has added a grade for cut to fancy shape diamond reports. In addition to traditional polish and symmetry analysis, the institute is now assessing the influence cut quality has on light behavior seen in shapes other than round.

                                                  Can this ‘Wizard of Oz’ Restore Diamond Magic Down Under?

                                                  The spellcaster in L. Frank Baum's fictional land of Oz may have been a charlatan, but the appropriately named Merlin diamond mine in Australia could potentially restore gem-quality diamond sparkle to that country.
