Riverstone is formed when calcium carbonate (limestone) is deposited by rivers, springs, or geysers as layers of sediment over a long period of time. These riverstone beads were stabilized and dyed. Testing for colorfastness recommended. (Actually, we recommend that you rinse and test ALL beads before using.) Bead measures about 4mm; temporarily strung to approximately 16" in length.  ONE (1) strand of 4mm round blue riverstone beads per package.
