These are natural lotus seeds. They are possibly given this name because they resemble the buds of a lotus flower, however, they do not come from the Nelumbo nucifera or Lotus plant. The white lotus is an important Buddhist symbol and represents perfect purity. Lotus seed is the name given to these beads in Nepal and India, they are typically seen as round beads and are very popular for Buddhist malas. The first time I encountered lotus seeds in this natural shape was in August 2009. each seed measures 18.40 mm x 15 mm
