Across 1,593 identical stones carried by more than one retailer, the typical gap between the cheapest and dearest listing is 386%, about SGD 1,297.

Listings refresh as we re-read each retailer, most of them every day. Static facts about each retailer refresh weekly.

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.
