This is Empress from the Royals Collection by Leigh Designs! The bling on this is awesome! I thought about photographing it in direct sunlight so you could see all of it! LOL
Here is the framed piece on display at the TNNA San Diego show the past weekend! I snitched the photo from the TNNA Facebook page.
