2 carat emerald cut heirloom diamond from my grandmother. It fell out of prongs during Charity Walk on Saturday, May 16th. Last seen at Hilton Hawaiian Village, then walked through to Ala Moana Park. Please call if found. I will pay $500 or more, it has so much sentimental value!! Walked on Ala Moana Blvd through park past tennis courts. Please call/text
