Sterling Silver Plum Blossom Charm Embellishment. This detailed Plum Blossom Flower Jewelry Component is perfect for customizing your Jewelry Designs! This Solderable Accent does not have a jump ring, so it can be easily soldered onto a custom Jewelry Design. The plum blossom is a unique flower because it blooms in the dead of winter, while there is still snow on the branches. In Japan, plum blossoms are treated as an early sign of spring, symbolizing the end of winter and the beginning of a season of warmth and fertility.
