Frequently asked

How much do retailers differ on the same diamond?

Across 1,490 identical stones carried by more than one retailer, the typical gap between the cheapest and dearest listing is 371%, about £564.

Can I see retailers for one exact grade?

Yes. Each of the 25 colour and clarity combinations above has its own page listing the retailers that stock exactly that grade.

No. We earn zero affiliate revenue from any retailer in our index.

How fresh is this data?

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.

Why do you not show per-retailer prices on this page?

Prices vary per stone, not per store. Click through to any matched diamond and you will see every retailer's price on the exact same physical stone, which is the meaningful comparison.
