Sources. Pearl facts come from GIA's gem encyclopedia, research articles and lab notes, the FTC's Jewelry Guides and consumer advice, and other named publications. Each page lists its sources. Checked October 22, 2026.
No invented numbers. We do not estimate prices. Reader price reports appear only after at least five people report the same kind of pearl, and we never show individual reports.
Colors on screen. The pearls drawn on this site are illustrations to show color, overtone, luster and shape. Screens vary, and real pearls change with the light.
