Pearl Attributes
Orient (the play of light and inner glow created by light refracting through the nacre of the pearl);
Surface Beauty (absence of spots, bumps, dimples or cracks);
Shape (generally, the rounder the pearl, the higher its value);
Color (pearls come many hues);
and Size (the average pearl sold is 7-7.5 mm, usually the larger the pearl the higher the value).
High-quality pearl strands and earrings will feature pearls well-matched in these characteristics.
