Earrings are handcut and sanded, for smoothness. A brass finding dangles from the earring with a small piece of tin adhered inside from a different complimentary tin.
Earring wires are antique gold-plated brass, 16mm flat 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.
