KREMENTZ silver necklace

KREMENTZ floral silver necklace vintage. From similar listings this should be from 1950’s. Also similar styles with the same chain list it as Italian Silver. I am not an expert but the chain is shiny and in excellent condition. I do not know what this is made of. I do know it is beautiful, has all stones, is about 15 inches in chain length and is super quality made. This is a score !!
