My rune stone focal is a fossil found here on Mackinac, probably some type of sea creature that once lived in the ancient sea that formerly covered this area.
My color palette is based on the colors of limestone, a variety of greys and used beads of varying sizes and finishes.
If you look closely, I tried to incorporate coral fossil forms in the beadwork. I once again left areas on the back open to allow the base stone to be visible.
I photographed this particular rune stone sitting on a very large fossil ammonite my husband found as a child.
