Earrings are handcut and sanded from the Vintage English Tin shown in the images. Iridescent midnight blue glass bead is added.
Ear wires are gunmetal-plated brass, 15mm fishhook with open loop, 21 gauge.  Each pair come with silicone clear earring backs. 
Earrings have been treated with a museum grade wax to protect and enhance, called Renaissance.
Some of the tins are vintage and have been lovingly used over decades. Therefore, there may be fine scratches or imperfections.
