The silver bud is of an agapanthus flower. It has been incorporated into a beaded necklace using the colors of the agapanthus plant. The bud was "captured from the wild", incorporated into a mold and then converted into pure silver. These plants abound this time of year and I love the purple color of the flowers, never paying much attention to the buds until recently.
 
The pendant is hung from a beaded necklace which brings out the purple and green colors of the plant. It measures 17.5" in length, and is closed with a sterling silver heart shaped toggle clasp.
