The Diamond Loupe June 16, 2015 In his latest Diamond Intelligence Briefings, Chaim Even-Zohar recounts the discovery and the documented reversal of a treated diamond, upgrading the stone temporarily by several grades, discovered at the Antwerp IGI lab in November last year. According to the IGI lab, the reversal process - through acid boiling -, which was witnessed and documented in an affidavit, revealed the diamonds were treated with a coating, temporarily upgrading the color grade of a 3.03ct diamond four grades, from J to G+ color. The precise nature of the coating, which may involve an very thin film visible only at 500 times magnification, is unknown. The article adds that the treated diamonds IGI discovered do not come from the same source(s) as the treated diamonds that were discovered by the GIA recently. IGI reportedly informed relevant trade bodies after the discovery to let them decide on taking disciplinary actions, but according to Even-Zohar, they kept silent.

Author“Visions of Beauty” is a video blog featuring customer directed custom designs ranging from the sublime to definitely ornate. It could be modern, vintage, classical, free form or anything else one desires. Customers bring to the table, pictures, sketches or ideas of what they want. With a good understanding of what they desire computer renderings are done for them to see if we understand their wishes. If the renderings are not right in their perceptions adjustments are made until they are satisfied. A wax model is then produced from the renderings which then show the exact size, height and width the ring will end up to be. If the wax is accepted then it is used to make the casting from which it is then finished and the diamonds are set. These are videos of the finished product. Each ring is exquisitely crafted to express the personality of the owner in creating their dream ring. Consider making yours today! Archives
