Aztag Mayan Calendar pendant Detailed piece

Beautiful gorgeous huge Aztag Mayan calendar pendant unisex Looks like a vintage cleaned it good it has a very detailed work not sure what the material is but it doesn't stick to magnets so I'm guessing it's silver but it doesn't have any stamp on it that's why selling it as a regular piece the pictures don't do it justice it's multipurpose can be hung on the wall or in a car or can be worn as a pendant It's silver with the vintage Black look
