RAPAPORT... The Gemological Institute of America (GIA) will host a presentation on ruby and sapphire treatments and pearls on August 27 and August 28, during the Japan Jewellery Fair in Tokyo. Ahmadjan Abduriyim, GIA's  senior research scientist and manager of colored stone services, will share the latest details about treatments applied to rubies and sapphires. Nicholas Sturman, GIA's manager of pearl identification, will discuss the colorful world of mollusks and their pearls.

These free GIA seminars will be held at the Tokyo Big Sight Exhibition Center. Abduriyim will detail the latest updates on ruby and sapphire treatments. The demand for natural, untreated rubies and sapphires continues to grow, but treatment processes that enhance the appearance of the stone are often difficult to detect outside of a gemological laboratory. Abduriyim’s presentation, “Gemological Observation of Ruby and Sapphire Heat Treatment,” will address how the GIA laboratories determine if a ruby or sapphire has been treated to improve its color or clarity.

Mollusks come in a range of colors, varied shapes, patterns and sizes.  From the world’s largest shell to the smallest, there are many reasons to appreciate these diverse creatures. One of their best attributes, however, is that they are able to produce pearls. Sturman will discuss important and frequently encountered pearl-producing mollusks, as well as some of the rarer ones. He will also cover topics related to their coloration, structure and optical characteristics.
