Yin and Yang... It is known to symbolize many interconnected and interdependent tangible dualities such as: male and female, sun and moon, light and dark, fire and water... This set contains: Two rings that exist very well separately but once united they form a perfect circle, they create peace between two forces. Two medallions designed to be easily disassembled and used as earrings. They can also be united. And assembled together, completing each other, they form perfect circle medallion; If you are interested, take a look at my other models, there is another version of this set, it's not assemblable and features just the earrings.
