Every diamond. Every price. One search.

Facet Wire is a diamond price intelligence service. We track live diamond listings across major retailers — Ritani, Blue Nile, With Clarity, Frank Darling and Ada Diamonds — and line up stones with identical specs side by side, so you can see what the same diamond costs from store to store.

No. Facet Wire doesn't sell diamonds, hold inventory, or take payment for stones. We compare prices and link out to the retailer, where you buy directly. Prices shown here are the prices we tracked — always confirm the final price on the retailer's page before you buy.

We match on the specs that define a stone: shape, color and clarity must be identical, and carat weight must be within 0.10 carats. Lab-grown is only ever compared with lab-grown, and natural with natural. We only call two listings the same stone when the certificate number matches at both stores.

Chemically they are the same material — crystallized carbon with the same physical properties. A natural diamond formed underground over billions of years; a lab-grown diamond is created in a laboratory in a matter of weeks. That difference in origin drives a large difference in price, which is why Facet Wire tracks lab-grown and natural stones in separate sections and never mixes them in one comparison.

Listings are refreshed nightly, and the homepage shows when the tracked data was last updated. Retailers can change their prices at any time, so treat Facet Wire as the radar, not the register — the price at the retailer's checkout is always the final one.

When identical specs are priced far apart at different stores — for example a 2.79ct pear listed at $1,668 at one retailer and $6,025 at another — that spread is a price gap. The Price Gap Alert on the homepage flags the biggest gap found in the latest tracked data, with links to both listings so you can check them yourself.
