Governance and disclosure

Ownership

Caratlytics is developed and operated by the team behind Carat Hunter (carathunter.com). The two sites share ownership, infrastructure and data. Caratlytics is not an independent third party and does not present itself as one: it is the published standard that Carat Hunter holds itself to.

Funding

Operations are funded by Carat Hunter's consumer subscriptions (the Carat Hunter Pass). We earn no affiliate commissions from retailers, charge retailers no fees, accept no advertising and sell no placements. No revenue line depends on how any retailer or stone scores.

Scoring independence

• Retailers cannot pay to influence a score, a grade band or index inclusion.
• No retailer sees scores before publication.
• The same methodology version applies to every retailer and every stone simultaneously; there are no per-retailer adjustments.
• Methodology changes apply from their effective date forward and are recorded in the public changelog.

Data practices

Scores and the index are computed from publicly listed retail data collected by Carat Hunter. We publish aggregates and methodology, not personal data. Certificate numbers shown in worked examples are quoted from public retail listings and verifiable with the issuing laboratory.

Corrections

If you find an error in the specification, a worked example or an index release, write to the address on the contact page. Confirmed errors are corrected with a note; index releases are corrected by publishing a superseding release, never by silent edits.

What Caratlytics is not

Caratlytics is not a grading laboratory, does not inspect physical stones, and does not provide investment, valuation or purchase advice. The score is a data product about listings on the retail market, with the limitations documented in the specification.
