Found this today,It is on a necklace(I am not sure it is suppose to be) but I'm not sure what it is.And the mark resembles H.H. curtis but I did not know they made jewelry. Anyway it is marked 925 over 1000 and the number 204 and this mark. any idea how old it is or who made it and what the heck is it anyway
It is about 3 inches x 3 inches
thanks
