These remarkably brilliant and colorful materials are from four specific dichroic films. They are Olivine Exotic, Olivine Mars, Olivine Mercury, and Olivine Titanium. These four materials are manufactured only in Vietnam. A black cord is included. Because each Olivine piece is unique, the pattern in your pendant will vary slightly from these pictures. However they are cut from the same film sheets and will be every bit as beautiful. Pendant Dimensions: 2” (50mm) H 1/2” (12mm) W
