For a fun design full of symbolism, try the antique pewter fertility pendant. This circular pendant features three rabbits chasing each other in a circle. They are each hopping above a ball. What makes the design so fascinating is that each of the ears is shared by two hares, so only three ears are visible. The design is on both sides of the pendant. This ancient symbol is associated with fertility, as rabbits are very fertile creatures. This pendant is made from pewter and features an antique finish for a dark, silvery shine.
