Jewels have a good deal more resale value than perfume, and I daresay the wise mistress made her gift wishes accordingly!
It's interesting how many of the jewel-named perfumes are on the cheap side, isn't it? Avon and Elizabeth Taylor. I've heard really good things about the Boucheron frags, including Jaipur.
I'm sure I don't need to ask whether you've read Colette's Gigi -- I just love her grandmother's tirade about "artistic" jewels. I would love to have any of the pieces she singles out for scorn!
