Frequently asked questions

Is MiaDonna or Ada Diamonds cheaper for diamonds?

On Facet Wire's live tracked data, MiaDonna lists 232 stones with a median of $1,175 ($775/ct); Ada Diamonds lists 153 with a median of $2,850 ($1,545/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 1.08 ct natural radiant (E color, VVS2 clarity) currently shows a $6,259 spread — $4,267 at With Clarity versus $10,526 at Blue Nile for matching specs.
