FACETWIREPrice IntelligenceFrequently asked questions
How Facet Wire tracks listings, matches stones across stores and flags price gaps — in plain terms.
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.
Not yet — Facet Wire is focused on the stone itself: comparing loose diamond prices across retailers. The retailers we link to sell settings, and most will happily set a stone you buy from them.
Retailers build very different margins into the same stone. Brand, overhead, inventory position and promotions all feed the sticker price, so two listings with identical shape, color, clarity and carat can sit thousands of dollars apart. That spread is exactly what Facet Wire exists to expose.
A certificate number ties a stone to its grading report from a lab such as GIA or IGI — it is the closest thing a diamond has to a fingerprint. Facet Wire records certificate numbers from listings, which is how we can tell when the exact same stone appears at more than one store. As coverage grows, certificate numbers will also power looking up one specific stone's tracked prices across retailers.
Yes — browsing listings, comparing prices and reading the guides is free. Facet Wire Pro is a paid tier for dealers and retailers who need competitor price intelligence, undercut alerts and deal flow. See the Pro page for what it includes.
