These earrings are lightweight and make a nice tinkly sound when the chains brush the mica. They are also just a tiny bit sparkly. Mica is a mineral that grows all by itself in these really flat, thin layers. It diffuses and reflects light and images and is very heat resistant. Mica is a perfect forum for embellishment with stamps of all kinds. Consider using Staz-on inks to add words or images to the mica or split the sheets and place photos, watch parts, feathers or leaves in between them.
You may wish to cut the pieces of mica if they are too large for your tastes. A sharp craft knife will slice through a sheet of mica. Drag the knife across the surface slowly to cut through one layer at a time. Be patient, this takes a while.
