I just came back from Paris. I visited the Place Vendone boutique, and met a very lovely SA. I inquired about the workshop tour and she was kind enough to schedule me in within the next few days. I was told they started this workshop tour only a few months ago. It's a hybrid/virtual type of workshop, so you don't get to visit the 'actual factory' per se, due to confidential/security purposes etc. The setting is nicely done, where you get to meet virtually all the major artisans, and also get to see (and touch) their samples, tools etc. At the end of the tour, I've learned a great deal about how their jewelry is made and being pampered from the very first step. It was fun, inspirational, and informative at the same time! Hope this helps
