I have the small open heart pendant and just bought the open heart earrings from eBay. The seller said these were a gift from a few years ago, and I do know that Tiffany's used to make the earrings in a larger size than the mini that is available now. I'm trying to figure out which size I have (they're bigger than I imagined). The earrings measure just over 1/2" at its widest part... can someone who has the mini size also measure and let me know? I went to Tiffany's website, but there's no info on sizing. TIA!
