Right now my studio works on a series of caviar and salmon packaging and we keep discussing what is premium in package design. There can be many types of packaging qualifying for that term, I think, while your clients rarely state what they really want. While browsing through the premium packaging examples, I found this one (from around 2007), created for Hennessy's Beauté du Siecle special edition. This unique bottle of Hennessy Cognac is worth $200,000 and it comes in crystle bottle by Baccarat and a chest, both designed by a French designer Jean-Michel Othoniel. Now, looking at this, I don't think my caviar is all that premium after all... :)
