Black and White Lichen
This ring contains dead/dying/unhealthy Birch lichen. Generally a dull green (think mint gum), the parts that begin to die take on a dark or lack of color, generally turning browns, grays, blacks and white. They also begin to become very brittle. These are tricky to find and work with, so I do have them listed at a higher price to reflect the work involved. I don't harvest more than needed (other things eat dead lichen).
