Treatment and Artificial Coloration of Pearls
(Mohave Room, 9:00 a.m. – 10:00 a.m.)
Elisabeth Strack, Gemmologisches Institut Hamburg, Germany. Intermediate - Advanced. Challenge your top sales people with in-depth information regarding ever increasing quantities, and treated and artificial colored pearls which are coming onto the market. Understand when and what type of treatments and artificial dyeing are applied. Learn about recent markets, what might need extra caution, what observations are necessary and when to get professional help. Strack offers a detailed overview on techniques applied for changing the outward appearance and color of cultured pearls and also concentrates on how far the naked eye and standard gemological testing methods can be used to detect treatments and artificial coloration. PowerPoint.
