Myriam Tashey

Professional Bio
 

Myriam is the Vice-President of PGSL. She is a second-generation jewelry industry veteran born in Antwerp, Belgium who has worked in different fields of the industry worldwide since the age of 18. 



Her diamond career began as a "pintler," drawing on rough diamonds to assess their wax and grain and carefully examining their inclusions to maximize the cut and weight of manufactured stones. Myriam traveled extensively from 1974 to 1979 throughout Africa, buying rough diamonds in South Africa, Rhodesia (present day Zimbabwe), Botswana, the Congo (present day Democratic Republic of the Congo), Kenya, and Sierra Leone, and sold those diamonds globally. She also bought and sold rough emeralds from the mines of Zambia and Brazil. In 1980 she moved to Los Angeles, California, where she and Thomas Tashey worked in the gemological field.



Together, Thomas and Myriam have brought many innovations to the jewelry industry. They were the first independently owned lab to do business globally. Some of the trends they brought to the jewelry industry were the diamond consultation, grading on-site at all major jewelry shows, sharing their database of graded stones online with Polygon subscribers via a "Polygon Upload" - known today as report verification - introducing the "SI3" clarity designation on reports, and editing The World of Color. From 1992 to 1997, Myriam was a career counselor at GIA's Jewelry Career Fair in Santa Monica, CA, and she continues to mentor individuals who want to further their careers in the jewelry industry. In 2008 she was presented by WJA with the "Woman Making a Difference" award for her valuable contributions to the jewelry industry. 

Myriam is an avid social media user. You can follow all her updates on gemological trends, fashions, finds, treatments, and best business practices on her Facebook page or on Twitter, by following @MyriamT18.
