All of the semi-precious beads are sold individually, by the ten or by the 40cm string and so high quality beads have never been so accessable. The beads do have small holes and so we would recommend that you use tigertail or Softflex for bracelet and necklaces. A tool that is also invaluable is the bead reamer...a hand held tool that allows you to enlarge and smooth holes of semi-precious beads and Freshwater pearls. Semi-precious stones also have meanings, representation and qualities, all of which can be found within our Crystal and Mineral Guide.
