Spiny Oyster Shell Adjustable Ring by Alfred Martinez, Navajo

Expertly handcrafted by Navajo artist Alfred Martinez, this adjustable ring features a beautifully cut tear drop shaped Spiny Oyster Shell stone, set in intricately detailed sterling silver.

According to research, spiny oysters are found buried at deep depths or attached to rocky reefs. The deeper they dig, the darker the pigment of the oyster shell which is how the colors range from a bright orange to a deep purple.
