Many people think of an oyster or mussel producing one pearl. In fact a mollusc may create over a dozen pearls depending on how it is seeded. Some of these are button pearls, so-called because of their shape - round on one side and flat on the other
Sold as temporary strung 36-40cm 14-16 inches (approx) strands. PLEASE NOTE: The beading hole sizes for pearls is traditionally much smaller than for gemstone/semiprecious beads as the most popular traditional stringing method is to use silk thread. Holes are approx. between 0.3-0.5mm. The industry standard for measuring pearls is in millimetres through their round diameter - perpendicular to the axis of the drill hole.
