Are Bigger Pearls Always More Expensive? Understanding the Many Factors Behind Price

Size affects a pearl’s price, but it is not the only criterion. Pearls of the same diameter can differ significantly in value because of variations in luster, nacre, surface condition, and shape. Rare origins, unusual colors, and excellent matching also influence price, but none should be judged separately from actual quality. When buying a single pearl, prioritize comparisons of luster and nacre; for necklaces and earrings, also consider how well the pieces match as a whole. Each small increase in diameter generally requires more cultivation time and involves greater risk, but a large pearl with weak luster and obvious blemishes is not necessarily a better buy than a smaller, finer one. After setting a budget, the rational approach is to find a balance among these different qualities.
