These earrings are made by Marika Desert Gold and are fully marked. The blackened texturing with golden shimmer is beautiful. These earrings are made with solid 18k yellow gold, and the blackened ring is sterling silver. The original retail price was approx $1800. Each earring has over 3 grams of 18k yellow gold. The 18k gold backings are also marked and original to the earrings. The overall weight of each earring is 7.8 grams. The overall length is 2" inches. As I showed in a picture, you're able to remove the gold rings if you want to wear silver& black assesories. Please take a moment to visit the Marika Desert Gold website to understand the wonderful processes and techniques used to handmake their products.
