The sale of treated corundum has dramatically increased the supply of products sold as ruby and sapphire. Accurately pricing corundum requires the professional gemologist to distinguish not only between treated and natural, but also between the various treatments encountered in today’s global market.
The workshop is designed to reconcile the pricing of rubies and sapphires by specific treatment type. Participants will examine a variety of natural and treated ruby and sapphire followed by a presentation concerning pricing considerations. The hands-on session is supported by a PowerPoint presentation featuring high quality images of certain characteristics that reveal if and how the stones have been enhanced.
Christopher Smith, President of the American Gemological Laboratories, is the scientific adviser of this program.
Cultured Pearls and Pricing Workshop
Cultured pearls are one of the fastest growing sectors in the gem trade. Many varieties of Chinese freshwater pearls have earned widespread consumer appeal across the global market. (Click Title to Read More)
However, visual similarity of these pearls to the once dominant seawater varieties like akoya and south seas have created some challenges for buyers, sellers and appraisal professionals whose responsibility is to accurately grade and price pearl products for their clients.
Today, cultured pearls are produced in an array of colors, shapes and sizes. Yet the standard remains the round to near round white products. Although visually similar, beyond appearance these products share little in common. Market availability, surface quality and of course price differ greatly from variety to variety as well as among pearls of the same variety. Accurately pricing cultured pearls requires the professional gemologist to distinguish not only between types, but also to correctly assess quality and shape factors within the same variety.
In this workshop, participants will examine and grade a variety of cultured pearls followed by a presentation concerning common enhancements and pricing considerations. The hands-on session is supported by a PowerPoint presentation featuring high quality images of certain characteristics useful for assessing overall grade.
