Many people are of the understanding that chalk turquoise comes from the grinding of unusable chips of turquoise left over from cutting beads. This type of bead is actually called ''reconstituted turquoise.'' The left over turquoise pieces are ground into a powder, or chalk, then mixed with resin and formed into sturdy shapes that can be used as beads. By using the turquoise chips for this process, reconstituted turquoise is very affordable to use in everyday jewelry designs.
