How to Use 珍珠指数计算器

The Pearl Index Calculator combines pearl market value, a quality coefficient and market average price into a relative index. Choose currency, enter the value, quality coefficient and average price, and monetary outputs display with the selected symbol.

The quality coefficient can represent luster, blemishes, roundness, size, color and matching. Average quality may be 1.00, premium quality may be 1.20 or higher, and below-average quality can be below 1.

Formula & Theory - 珍珠指数计算器

The index is not an official market quote. It adjusts current value by quality coefficient, then divides by the selected market average to express a relative multiple. A value near 1 means close to average; higher values suggest stronger relative value.

Pearl pricing also depends on origin, certificates, brand premium, matching and sales channel, so the index supports comparison but does not replace appraisal or transaction data.

Pearl index = (current pearl market value × pearl quality coefficient) / market average price

Use Cases for 珍珠指数计算器
