Earrings are made with natural Turquoise flat rounds, red spiny oyster rounds, and finished with a sterling silver round bead (Navajo pearl). Earrings measure approximately 3.5 inches in length and 0.5 in diameter. Ear hooks are nickle-free. This pair is not heavy to wear although it is a little more dense than my other earrings. Not recommended if your ears are sensitive to weight.
