I wonder about the same thing!
During the 90's my DH gave me a lot of david yurman. Many pieces have dark red (not purple) garnets, pearls and diamonds. A lot of the equestrian style....a watch, necklace, those cable bracelets, several pairs of earrings.... It's pretty but feels dated to me now.
Once in a while I'll see somebody wearing it and I think that I should drag it out....although I don;t think I will ever wear any of those earrings again.
