Thursday April 3 Morning Practical Workshop held at the CGA classroom
Pearls Dr. Cigdem Lule
CGA Member $195 Non Member $245
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. 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.

Emerald specimens have been specifically treated for this program to illustrate the common treatment types and levels of enhancement encountered in the market.

Identifying Diamond Types and Synthetic Diamonds with UV lamp, Microscope and Polariscope Branko Deljanin, B.Sc., GG, FGA, DUG
CGA member $185, non-member $195; includes CPF booklet ($25 value)
The use of treatments based on high-pressure, high-temperature (HPHT ) annealing, low pressure annealing and irradiation with energetic particles with the aim to alter the color of diamonds has become increasingly popular in the past 10 years. Diamonds can be also grown in the laboratory (HPHT or CVD) and these synthetic diamonds could be colorless (type IIa), yellow (type Ib ) and blue (type IIb ).
This lecture and workshop is designed for dealers, gemologists and appraisers. You will learn to identify different types of diamonds and synthetic diamonds. You will also learn about possible treatments/synthetic diamonds and their relation to types in order to know when to send stones to an advanced lab for further testing for natural, treated or synthetic origin.
