How Facet Wire tracks prices

No estimates, no sponsored order — just observed listings and their history.

01We scrape listings

Every sweep records retailer, URL, price and the full 4Cs plus cert lab and number — never overwritten, always appended to price history.

02We match the stone

Listings collapse to one canonical diamond by (lab, cert number), so the same stone at four stores shows side-by-side with a best-price badge.

03

We flag the moves

Drops over 5% get a price-drop badge; first-seen dates prove who carried a stone first. Stale listings age out of every best-price computation.

Freshness rule: a price counts toward best-price only while its listing is freshly seen (hourly retailers < 2h, daily < 30h). Older rows stay visible with a "last seen" note.
