Vintage Green Banded Onyx mortar & pestle (Missing pestle).
This was an Estate find. I thought that this was made from some type of marble but apparently, according to my research, it is actually Green Banded Onyx.
It is a mortar & pestle BUT IT IS MISSING THE PESTLE!! No pestle included at all, just mortar.
I think this was from the 1960s to 1970s. There are no markings on this piece except on the bottom you can faintly see where someone wrote the numbers: 170, which you can see in the next to last picture.
