Tissue-nucleated pearls can grow freely in all directions. Potato pearls are short ovals that are drilled vertically (the shortest direction). The slight out-of-round shape gives a larger look, with a more organic feel.
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.
