Heishi (also spelled heishe) are a style of small disk or tube-shaped beads that have been formed by humans for thousands of years. Traditionally, heishi were ground down by hand. TierraCast metal heishi are cast in the USA using modern techniques and lead-free pewter to give you high quality metal beads in several styles. Nugget heishi mimic the organic look of ancient heishi beads. Faceted heishi are hexagonal (6 sided) spacers. Regular heishi offer smooth round disks, and additional styles provide you with fun textures to play with.
