Although this looks convincingly like tortoise shell, rest assured no animals were harmed so you can look stylish. By Machete, they explain “The tortoise shell acetate we source is high quality and non-petroleum based, imported from Italy. Cellulose acetate is a natural and renewable material, providing an eco-friendly alternative to petroleum-based material.

Cellulose acetate is made by extracting cellulose fibers from cotton and wood pulp to create a transparent paste. This paste can then be colored, processed, and molded for a variety of industrial applications. For our jewelry, it is cut from a large block into thin sheets, and then cut again into smaller rectangular blocks. All of our earring posts are made from hypoallergenic stainless steel.”

These are available for USD$38.
