This 18k gold and diamond pendant by Tate, dubbed the White Diamond Petite Pendant and available exclusively at Barneys, is definitely petite. They don’t list the diamond weight but I would be surprised if it’s more than .10. Having said that, it’s a pretty and discreet piece if you want something with a tiny bit of sparkle. It sells for USD$1,295 and comes with a 16 inch polished 18k yellow gold chain.
