Are larger pearls always better quality?

While size can influence the value of a pearl, larger pearls are not always better in quality. True pearl quality is determined by several factors—including luster, surface condition, shape, and nacre thickness—not size alone.

Larger pearls like South Sea or Tahitian varieties are often more expensive due to their rarity and long cultivation periods. However, if a large pearl has weak luster or visible surface imperfections, it may be less desirable than a smaller pearl with a brilliant, mirror-like shine and a clean surface. For example, a 7mm Akoya cultured pearl with excellent luster and perfect roundness can be more valuable than a 10mm pearl with dull shine and many flaws.

When buying real pearl necklaces, real pearl earrings, or real pearl rings, focus on overall balance—size should enhance the design, but luster and surface quality matter more. This is especially true in dainty pearl jewelry, where smaller pearls with exceptional luster create understated elegance. Baroque pearls, though often larger and irregular in shape, are prized not for size but for their artistic beauty and rich personality—making them popular in freshwater pearl jewelry and unique pearl jewelry gifts for her.

In short, bigger doesn't always mean better. A well-matched, high-luster, smooth pearl—regardless of size—is the true mark of quality.
