Bonanno Award for Excellence in Gemology at the evening Gala.

Gemstone Paternity Test

The cutting-edge technology behind gemstone traceability will be explained by Daniel Nyfeler, Managing Director of Gübelin Laboratory, Switzerland. Nyfeler will share the lab’s program to identify the history of gem materials combining DNA tagging and blockchain accountability. Initiated with emeralds in partnership with Gemfields, the “Provenance Proof Initiative” brings the discussion of industry transparency to the forefront.

Pearls of the New World and Beyond

Gina Latendresse, Tennessee, grew up in the American freshwater pearl business and is now one of the world’s leading authorities on U.S. as well as exotic natural pearls. She will trace the origins of a market that captivated Europe hundreds of years ago and continues to be a vibrant industry niche as well as supply for nucleus material to the Tahitian pearl market. Attributes of other natural pearls, including conch, Baja, Melo and Quahog will be examined as well as some telltale signs of when a pearl was cultured.

An In-depth Look at Tourmaline

A complex group with stunning color variation and marketing possibilities will be explored by Dr. Claudio Milisenda, Managing Director of the German Foundation for Gemological Research (DSFF), Germany.  Dr. Milisenda will cover the varieties and qualities of tourmaline at market, discuss origin factors and treatments now encountered in the laboratory.
