How every comparison is scored
Published weights, the same basket at every store, sources on every policy line. Every retailer is scored on the same five criteria and the numbers are shown. Read the full method or open the Policy Register.
| Verified price on identical specifications | 25% | We price a fixed basket of stones and finished pieces at each retailer on the same day and record the listing. |
|---|---|---|
| Certification and physical verification | 20% | Does the retailer sell only GIA, IGI or GCAL graded stones, and does it inspect the stone and laser inscription before delivery? |
| Inventory depth and imaging | 15% | Number of certified stones searchable online, 360 video on the listing, and filter precision. |
| Published policies | 20% | Return window, resizing, warranty, upgrade program and insured shipping, taken from the retailer's published policy pages and recorded in our Policy Register. |
| Expert access and reviews | 20% | Commission-free advice before purchase and what independent review platforms show (Trustpilot, Google, BBB). |
