Frequently asked questions

Is Ritani or Blue Nile cheaper for diamonds?

On Facet Wire's live tracked data, Ritani lists 26 stones with a median of $116 ($333/ct); Blue Nile lists 176 with a median of $592 ($697/ct). Medians mix shapes and sizes — the honest test is the same certified stone at both stores, which is what the table below tracks.

Do the same diamonds appear at both retailers?

Stones with identical specs — same shape, carat, color, clarity and cut — routinely appear at multiple retailers at very different prices. Facet Wire matches them spec-for-spec so the gap is visible before you buy: one tracked 2.79 ct pear currently shows a $4,357 spread between the cheapest and priciest retailer.

How often is this comparison updated?
