Further, we are exicted to announce the lecture about "The Gemstone Market: A Historical Perspective" given by Helen Molesworth.
The jewelry industry and gem markets have seen great change and development in recent years, apparently more than ever before. Markets have experienced both growth and fluctuation on a massive scale. World records are constantly being broken. Recent sales results are frequently observed and discussed. Yet all this often happens without a larger context. Much of our price and value knowledge comes from recent, living memory… but what do we know about gem pricing in the recent and even distant past? How have we gotten to where we are today, compared with a hundred or more(!) years ago? How has our concept of prices and value changed? Furthermore, can this help indicate where we are going? Helen will address the importance of history through examples and models, with special references to Ruby in particular. She’ll also investigate shifts in the gem market from the perspective of the bigger picture.

Date: Friday, 7 February 2020
Time: 1:00 p.m until 2:00 p.m.
Location: Greenle Room at the Tucson Convention Centre

Registration is not required, but seating is limited.


We look forward to seeing you in Tucson!
