Like the matching pendant, this colorful material is a specific dichroic film called Olivine Titanium, manufactured only in Vietnam. Because each piece made from Olivine Titanium is unique, the pattern in your earrings will vary slightly from the pictures. However they are cut from the same film sheet and will be every bit as beautiful.
