The ancient Chinese coin is round on the outer side, and square on the inner side (天圆地方). It is a philosophical thought in ancient China and a manifestation of the theory of yin and yang. The sky and the circle symbolize movement; the earth and square symbolize stillness; the combination of the two is the balance of yin and yang, and the complementarity of movement and stillness. So, an Ancient Chinese coin represents balance, harmony, and peace. 

Size: 18-19.6mm 

No crack. No hairline. May has a cotton area, and cotton spots, processing makes. The square may not be a prefect square. The purple is lighter than in photos since purple is very camera friendly

Without a certificate, 100% natural jadeite jade is guaranteed.
