These are about 3/4 of an inch long. I call them petite in terms of size. Marked as 12kt gold filled. Natural carved shell. There is a bit of crazing on one of these although not something that would ever be noticed if worn. The pictures are blowing things up 500%. Good shape overall. We do not polish antique jewelry. Not sure the age on these somewhere in the 60-70 year old range I would think. Comes gift boxed.
