When you said that, Dave, initially at first glance I thought you were probably right but in looking @ the pictures of the matching necklace on Ursula's site & comparing it to pictures of the 'Greville' necklace, they are similar but not the same (unless it's been altered, of course). The diamonds around the center emerald are round vs. square & the diamond spacers between the emeralds seem to be very different, as well.
