Mayors jewelry 2 colors 14K white gold diamond bar drop necklace

Gorgeous necklace in original packaging. This was a gift in 2008 I never ever wear. I count 15 stones in each side. White and rose. I never get it appraised so the prices is what I Google it. The case (box) has some damages from storage but it is the original. The original pouch has not stain or damages on it. 20 inches length of the chain
