Sterling silver with moonstone cabochons, around 7mm in diameter. French wires.
The earring shape itself is about 1 1/2 inches tall. Lightning bolt or rik-rak.
I modeled the lightning bolts on the computer in Zbrush, 3d printed it, had a mold made which was used for the wax for the cast in silver. I do my own finishing.
Allow 1-2 weeks for shipping.
