13x8mm Antique Silver Botanical Bead by TierraCast. The Botanical Birds collection is the result of a whimsical collaboration with renowned jewelry artist Jill MacKay. This tiny representation of birds and foliage brings to mind springtime and that special quality of light falling through the patterns of branching trees. Think of all the graceful greens in nature and wings that take flight. TierraCast creates components that lift your imagination and inspire you to create beautiful jewelry adornments, but also act as touchstones of the beauty all around us. These lead-free pewter beads are made with high quality metals right here in the USA! Sold individually.
