Two earrings in one. First you have a simple stone stud, your choice of american turquoise, azurite/malachite and copper calcite. Second, you have a larger piece that slides between your ear and earring, a hammered arc shape with textured drops.
Azurite/Malachite, mined in New Mexico is a deep, inky blue with occasional bright green sparks.
Turquoise, mined in Nevada is a beautiful and consistent robins egg blue.
Copper Calcite, mined in Arizona is an ivory/peach with coppery gold.
