Zodiac MedallionZodiac Medallion. Although we are all different, we are all one The Zodiac Medallion is designed and hand crafted in Melbourne using solid 9crt gold and raw sterling silver. When designing the zodiac medallion, I wanted to symbolize although we are different we are all one. The three solid gold balls represent; past, present and future. The gold in the middle of the 12 star signs represents healing and letting go, which is needed in order to evolve.
