Pearl Quality Factors
When considering pearl quality, experts consider origin, lustre, shape, size, surface, and nacre thickness. When parcelled as a strand or pair, one also considers how closely the pearls match. Here’s a brief description of what makes a pearl most precious.
Lustre
Indicating a thick layer of nacre, lustre refers to the reflective, glowing aspect of a high-quality pearl.
Shape
While there are plenty of reasons to love irregular Baroque and Keshi pearls, a perfectly spherical shape is typically most valued.
Size
The larger the diameter, the rarer the pearl, which usually translates into a greater price across all varieties.
Surface
Ideally, a pearl’s surface should be free of cracks, bumps, or irregularities of any kind.
Color
The most popular colors are flattering against skin tones: silver, white, and light pink pearls suit fair complexions, while cream and gold-tone pearls glow against darker skin.
