You just continue to get better and better through the years!
The visual balance of this piece is very nice, the crown and side jewels really compliment the main setting jewel.
The color choices really compliment each other, and I do love purple, black, blue and silver!
I might have chosen a different drop pendant for the bottom, it doesn't really have the same feel as the main setting and side pieces. Something a little more baroque, in my opinion, that echoes the leaves and ornamentals on the main setting.
But, I would certainly wear this piece, as is! Kudos!
