Caron's Violette Précieuse, a 1913 fragrance by perfumer Ernest Daltroff that was the favorite of many violet fans before it was discontinued, is back on the market. The French Sephora site has it in stock (and says it is an exclusive) for 51,30€ for 50 ml of Eau de Parfum.
Update: by all accounts, Violette Précieuse has been reformulated and is quite different from the original. Try before you buy!
