I have had pins just like this before signed Krementz. This is only marked 14 Karat on the pin stem..... anonymous. I think I'll upload a picture of signed Krementz so you can compare :) Krementz is marked on a different type of clasp (see the last 2 images) with its distinct mark. I know several companies made these in a variety of sizes. This one is 2 by 1 inches and in excellent condition.
