Paris jewelry

Dear All,

I've got a question, are the wedding rings in all sizes available in Paris ? and if so, which locations sell these rings ?

For fine jewelry, your best option is Louis Vuitton's boutique 23 Place Vendôme in Paris. This store is specialized in jewelry - definitely worth the trip.
 
I'm now in paris, bought a ring from lv. Prices are perfectly displayed. Friendly people. Bought also a tie from goyard. My day is perfect.

The pieces i've seen are soo beautyfull. I was there in jeans, not formall clothes and i think they didn't care
