June is Pearl month. This is how pearls are graded.
Pearls are timeless classics and are prized for their luminous glow. Whether you’re drawn to large South Seas, dramatic Tahitians, bright akoyas or colorful freshwater pearls, here are key factors to consider when evaluating a pearl:
Size: South Sea pearls are typically the largest, reaching 15mm or more. Akoyas over 9mm are considered large.
Shape: While round pearls are the most valuable, off-round strands can look round from a distance and baroque strands can make for affordable statement pieces.
Color: Overtone, orient and popular bodycolors such as deep gold can increase the beauty and value of pearls.
Luster: This is one of the most important value factors for pearls. South Seas are known for their soft, satiny glow, while akoyas are known for their bright, mirror-like shine.
Surface: This refers to whether the pearl has any surface blemishes such as dimples and scratches. High surface quality pearls should be smooth and clean.
Nacre: Consider the continuity, thickness, and condition of a pearl’s nacre when evaluating pearl quality. Avoid pearls that appear dull or chalky, or where the nucleus is visible beneath the nacre.
Matching: In a well-matched strand, pearls should be consistent in key quality factors—especially luster, shape and surface. Designers may occasionally mix colors or use graduated sizes for artistic or unique effects.
