This is a popular item the crescent moon / horn in gold or silver. This is a beautiful minimalist necklace hung on an 18" gold or silver plated chain. The crescent moon charm is approx 1/2" across. If you would like a different length just message me on purchase I'm happy to adjust. Each necklace comes in a white jewelry box with a polishing cloth and a gift card ready for giving. Makes a great gift.
