Large Belt Buckle Made in Israel by Elanomi - Might Be Sterling - Any additional info would be great! I don't know much about the maker, and have only found a few things about this maker online. I am getting acid tomorrow and I'll test it to see if it's sterling. Everything I have seen from this maker has been sterling. What type of design do you think it is? Do you know what kind of stone is in the middle? Anything would help!! Thank you all so much in advance!
