Medical texts prescribed Chalcedony to strengthen the eyes and treat eye diseases, to increase lactation in new mothers, as well as a cure for depression. It was specifically suggested that Chalcedony be worn as a bead and strung on donkey’s hair for best results, regardless of what specific protection, healing or good luck, was desired from the stone! When studying Chalcedony, it is beneficial to also explore donkey as a totem animal. Donkeys are hardworking, intelligent, and patient. They can be stubborn and resistant to change, but they are willing to serve others and work for the greater good. They thrive when offered kindness and humbly keep their faith in a better tomorrow.
Natural blue stones are relatively rare, and in the case of Blue Chalcedony each deposit has its own distinctive shade. As a result, many of the deposits have distinct names associated with them, such as Ellensburg Blue (found near Ellensburg, Washington USA), Holly Blue Agate (found near Holly, Oregon) and Mount Airy Blue Agate (found near Mount Airy, Nevada).
