Why it surfaced
CaratAtlas publishes a full colour-by-clarity grid across carat bands, reports 23,461 observations, and draws ten cuts to compare face-up size and geometry. Its plainspoken lessons— including “Magic sizes: the price cliff at 1.00 carat”—make an expensive, opaque market unusually legible.
