In this session, Arthur Skuratowciz offers some common "red flags" to help you uncover all of the problem areas in a piece of jewelry. He'll also suggest some handy tips to ensure those repairs go as smoothly as possible.

Proof of Provenance
MARICOPA ROOM1:00 - 2:00 p.m. 
Klemens Link, Director of Development, Gübelin Gem Lab, New York
Beginning - Intermediate - Advanced
Consumers request more transparency on the provenance of the goods and services they purchase, and also applies to luxury products including gemstones. In stark contrast to this demand, the gemstone trade has a reputation of being opaque. No proper solutions are in place today that truly close this gap: the classical, gemology-based origin determination offered by gem labs merely states the country of origin, and cannot distinguish different producers mining the same geologic unit. Some mining companies have started to issue certificates of provenance, offering information such as the name of the mine, the mining company, and the mining period. The information provided in these documents, however, is largely based on self-declaration, i.e. is not an independent proof of provenance.
Rediscovering the Chivor Emerald Mine -
In the Footsteps of Peter W. Rainier
MOHAVE ROOM1:00 - 2:00 p.m. 
Robert Weldon, G.G., Manager of Photography and Visual Communications. Gemological Institute of America

An epic story of triumph over adversity, Peter W. Rainier, a South African, ran Colombia's Chivor emerald mine in the 1920s. He fought bandits, chased elusive emerald veins, and rode across the Andes. His story, revealed in his memoir Green Fire, was licensed by MGM for a movie starring Grace Kelly and Stuart Grainger.
Rainer brought Chivor into peak production, extracting the finest emeralds the world had seen. He fought in both World Wars, and helped defeat Rommel's troops at El Alamein. The rediscovery of a lost album of historic photos sparked the idea for a journey to retrace his path.
