Beautiful old award/merit pin with a star inside of a crescent moon. It is not marked, but tests absolutely as at least 10k (actually holds up to 14k acid, but turns a red shade, which I believe is indicative of very good 10k). Moon and star hang from a badge which could be engraved. It weighs 1.6 grams. The pin back is not gold. I am listing a couple of other gold award pins from this same estate and am happy to combine shipping costs!
