These two pieces were found in the same area of Ayrshire and look like they were once part of the same rock. This material is a lot like banded calcite but with shiny jasper or chalcedony lines through them. 
These pieces have been in the rock tumbler. Since they are a mixed material the hardest parts took a shine while the calcite did not.
Looking to be removed asap. From a smoke free home with only two rockhounds.
