The dragonflies are pure brass stampings, and are soldered onto sterling silver. Earrings measure 1/2 inch, and dangle just over an inch including the handmade fine silver ear wires. The natural amethysts measure 4mm in diameter - about 1/8 inch.
If amethysts are not your color, just let me know in the message to seller when you place your order, and I will be happy to substitute different stones - I have most stones in stock.
These go nicely with the Amethyst Moon pendant here: https://www.etsy.com/listing/52435882/dragonfly-pendant-in-sterling-silver
