Terms

Last updated 31 August 2026

These terms cover this website. They do not cover the product. Any supply of an instrument, software or service runs under a separate written agreement, which takes precedence over anything here.

How to read the grading claims

The system assigns grades by machine, from measured optical, spectral and dimensional signals. It is an instrument, not a gemmological laboratory, and its output is not a laboratory report. Where value or a filing turns on a grade, treat the record as a measurement and apply your own commercial judgement.

Where the system identifies a stone as laboratory grown, it records it as laboratory grown, in that wording. Disclosure at the point of sale remains the seller’s obligation under the FTC Jewelry Guides at 16 CFR Part 23.

The documents shown on this site

The grading report and the due diligence statement on the home page are specimens, marked as such on their face. They illustrate the records the system writes. Neither describes a real stone or a real shipment, and neither is a valid certificate or a valid statement.

Forward looking statements

Throughput figures and capabilities described here reflect the system as designed and are targets, not guarantees. Nothing on this site is an offer of securities.

Intellectual property

The text, layout, marks and visuals on this site belong to Jewel Labs. You may read it, quote it briefly with attribution, and link to it.

No warranty on the site

This site is provided as it is. To the extent the law allows, Jewel Labs is not liable for indirect or consequential loss arising from your use of it. Nothing here limits liability that cannot lawfully be limited.

Governing law

These terms are governed by the laws of the State of New York, United States, without regard to conflict of laws rules, and do not remove any protection you have under the mandatory law of your own country of residence.
