What the retailer and appraiser need to know to recognize these gems and their proper disclosure

Abstract: In today’s market, ruby remains one of the most popular gems sold at the wholesale and retail level. Yet never more than now have such a breadth of various treatments existed in the marketplace for this revered gem. Unaltered versions of these gems are available, but the majority of rubies sold in the US and abroad have undergone some form of enhancement or treatment. These range from simple or rudimentary forms of enhancement that are easy to detect, to the very sophisticated, requiring advanced analytical techniques to identify. This lecture and workshop will review natural ruby available in the market today - both untreated and the various forms of treated.  It will also include lead-glass treated, otherwise known as Composite Ruby. Guidelines for how the average gemologist may recognize these various ruby treatments will be provided.  In addition, the first 30 attendees will have the opportunity to examine a number of examples.
