Presenter: Stuart Wilensky

Mr. Wilensky will present on the process of emerald specimen evaluation. This exhibition will focus on natural emerald, both in its natural form and in its preserved specimen and crystal form. By bringing together many of the world’s finest known examples of natural emerald specimens, we can better understand all emerald specimens. We estimate that there are less than 25 exceptional natural emerald specimens in the world. Of those 25 specimens, half of them are on exhibit at the Wilensky Exquisite Mineral Gallery.
