Rough Blue Lace Agate

These blue lace agate pieces are from the famous mine (RECENTLY CLOSED!) in Namibia. Each piece displays various light shades of banded blue agate, NOT unbanded chalcedony. The bands tend to run fairly straight, as the blue lace agate is a seam formed between layers of host calcite. May contain traces of brown calcite.
Size: from 1/4 inch to .5 inch long.
Some are thin chips, others are small piece
