Thanks Duke
found a picture of queen nazlis van cleef & arpels necklace worn by barbara hutton the famous american heiress , i wounder if she was the one who bought it from the queen's jewellery auction .
To make it sure: It is Eva Peron!
I'm pretty sure that is Eva Peron not Barbara Hutton. Here's another picture of her wearing the necklace.
