I am so excited for you and your gorgeous piece!
On the metal question, yes... it's so funny. All I wanted was an Alhambra set, but instead of using WG for the metal, I asked them to use Platinum (I know, no one will know if it's WG vs. Platinum, but I will know).
Horrors! What? You want to use Platinum for the casual Alhambra line? I now know that's what they were thinking, but the gentlemen was very polite and explained "No Madam, Platinum is usually reserved for our High Jewelry".
I am sure there are exceptions of course.
On L'ECOLE, there are two permanent schools and three travelling schools. A travelling school is where they come to the location every few years. The travelling schools are in NYC, Dubai, and Tokyo. The two permanent schools are in Paris and... Hong Kong! Yes... HK... just a hop and skip away from you!
They do exhibitions as well as hold classes. If you are interested, I would suggest you take a week and sign up for classes back to back and just enjoy the week there. I did that when L'ECOLE came to NYC. I just packed in as many classes as I could during that week. It was so worth it.
Regarding Switzerland vs. Paris, I am almost certain their main workshop is at Place Vendome in Paris. It's been there since VCA opened at Place Vendome in 1906 (hence their logo is the Vendome Column). VCA was bought by Richemont (same owner of Cartier) in 1999, so based on what you asid, I wonder if Richemont opened a workshop in Switzerland. I would love to hear what your SA says about a workshop in Switzerland, and if it's true, is it for any Richemont brand (e.g. VCA, Cartier, Buccellati...) or specific for VCA?
Here is the link to the L'ECOLE so you can browse overall. Then scroll all the way to the bottom and click on the HK school. Wow... you are so lucky you are close to a permanent school.

By the way, I travel a lot on business (well, used to) and used to fly to Asia. SG is beautiful, but soooo hot! I was in suits, dying of heat.
During my business trips, I often went to SG, but I would do a quick hop over to HK for the weekend. I think it's only a little over 4 hours, but that's a short flight when you're talking travel in Asia as I am sure you know. Take a look at the website and classes and see if any interest you. I really enjoyed them and plan to take more classes when L'ECOLE comes back to NYC.
I am sure you're going to love this piece even more knowing it's high jewelry!
I went back to your original post and it's gorgeous. Please post mods shots if you're not shy.
So happy for you!
