I've been checking out the comments for this movie and am slightly surprised that no one has noted what appears to be a fairly obvious metaphor. Diamonds are cold, hard, many faceted and beautiful. Catherine Deneuve is the star here. I rest my case. There is, of course, more to it than that but not a lot more. It's French so it's stylish by definition but Nicole Garcia, like so many French actors/writers/directors, was born in Oran, Algeria - gateway to Lisbon and, by definition, a free world, as we learned in the first reel of 'Casablanca' - so there's also something of the outsider element, the shopgirl who came to the ball because her beauty captured the heart of the Second Son, and who feels always slightly uneasy that it all may end tomorrow. So, what do we get for our money? Style, opulence, quasi-noir, great acting. Is that enough? You tell me. 7/10
