Across 27,970 identical stones carried by more than one retailer, the typical gap between the cheapest and dearest listing is 163%, about $1,046.

How is the retailer ranking calculated?

Strictly by active inventory count for this exact spec. The retailer carrying the most stones at the spec ranks first. There is no editorial input, weighting or affiliate consideration.
