The colors on these earrings are amazing. You will feel transported to the tropics when you look at this beautiful natural blue agate. This agate has tones of turquoise, earth, and aqua. I dangled these with copper and teal glass beads on gun metal dagger pins. I love the movement of these earrings and I think you will too. The pins are on gun metal plated steel chain. The ear hooks are surgical steel and come with little plastic safety backs to keep them secure. Shipping is free in the continental US.
