Terms of Use

Last updated: May 5, 2026

1. Acceptance of Terms

These Terms of Use (“Terms”) govern your access to and use of the DiamondCheck AI website at diamondcheck-ai.com and the DiamondCheck AI iOS application (collectively, the “Service”), operated by Mizrahi Diamond (“we”, “our”, or “us”). By accessing or using the Service you agree to be bound by these Terms. If you do not agree, do not use the Service.

2. The Service

DiamondCheck AI provides AI-assisted diamond pricing estimates based on the Rapaport wholesale price list and an artificial-intelligence model trained on historical grading data. The Service includes:

  • A free web tool for looking up GIA-certified diamonds by certificate number or by uploading a certificate image.
  • A free web price calculator for entering diamond specifications manually.
  • Educational guides about diamond pricing and grading.
  • An iOS application that unlocks a full report including a deduction breakdown, negotiation guidance, and a letter grade, available via in-app purchase.

3. AI Estimates Are Not Appraisals

The Service provides estimates, not appraisals. All prices, grades, and analyses produced by the Service are computer-generated estimates based on publicly-available benchmark data and machine-learning models. They are provided for informational and educational purposes only and:

  • Are not a substitute for a formal appraisal by a certified gemologist;
  • Are not financial, investment, insurance, or legal advice;
  • Do not establish a contract price between any buyer and seller;
  • May contain inaccuracies, particularly when based on uploaded certificate images analyzed by AI vision.

Always verify any diamond's value with a certified gemologist before making financial decisions. We make no guarantee that any estimate reflects the actual wholesale or retail value of a specific diamond.

4. Eligibility and Use Without an Account

The Service is intended for users aged 13 or older. The web tools do not require an account; the iOS application uses a randomly-generated device identifier (not tied to your Apple ID) to manage in-app purchases and scan history. If you do not agree to these Terms or are not eligible, do not use the Service.

5. License to Use

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your personal, non-commercial purposes. All rights not expressly granted are reserved.

6. Acceptable Use

You agree not to:

  • Scrape, crawl, harvest, or otherwise extract data from the Service in bulk, except for properly-credentialed indexing by search engines via our public sitemap;
  • Reverse-engineer, decompile, or attempt to derive source code from the Service;
  • Use the Service or any output for any commercial pricing, appraisal, or resale service without our prior written consent;
  • Upload certificates or images you do not have the right to use;
  • Interfere with, disrupt, or attempt to gain unauthorized access to any part of the Service or its underlying infrastructure;
  • Use the Service to violate any applicable law or regulation.

7. In-App Purchases (iOS)

The iOS application offers in-app purchases for unlocking full reports. All purchases are processed by Apple Inc. through the App Store and are governed by Apple's standard payment terms and the App Store Terms and Conditions. We do not receive or store your payment information. Refunds for in-app purchases are handled by Apple in accordance with Apple's refund policy.

8. Web Payments

Where the website offers paid features, payments are processed by Square, Inc. We do not store full payment card numbers on our servers. Your payment information is handled in accordance with Square's privacy and security practices.

9. Third-Party Services

The Service relies on third-party providers including, but not limited to, Apple (App Store, App Hosting), Square (payments), Supabase (data infrastructure), the Gemological Institute of America (publicly-available certificate verification), and Rapaport (wholesale benchmark pricing data). We are not responsible for the availability, accuracy, or terms of those providers' services. The Service is not affiliated with, endorsed by, or sponsored by the Gemological Institute of America or Rapaport.

10. Intellectual Property

The Service, including all software, designs, text, graphics, logos, and the DiamondCheck AI name and brand, is owned by us or our licensors and is protected by intellectual-property laws. You retain all rights in any certificate images or inputs you upload; by uploading them, you grant us a limited license to process them solely for the purpose of providing the Service to you.

11. Disclaimers

THE SERVICE IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS, WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THAT ESTIMATES PRODUCED BY THE SERVICE WILL BE ACCURATE, COMPLETE, OR RELIABLE. WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE.

12. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL WE OR OUR AFFILIATES, OFFICERS, EMPLOYEES, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US, IF ANY, IN THE TWELVE MONTHS PRECEDING THE EVENT GIVING RISE TO LIABILITY, OR (B) ONE HUNDRED U.S. DOLLARS ($100).

13. Indemnification

You agree to indemnify and hold us harmless from any claims, losses, liabilities, damages, costs, or expenses (including reasonable attorneys' fees) arising from your violation of these Terms, your misuse of the Service, or your violation of any rights of a third party.

14. Modifications to the Service and Terms

We may modify or discontinue any portion of the Service at any time, with or without notice. We may also update these Terms periodically; the “Last updated” date at the top of this page indicates when changes were made. Material changes will be highlighted on the Service. Your continued use after changes become effective constitutes acceptance of the revised Terms.

15. Termination

We may suspend or terminate your access to the Service at any time, for any reason, without notice. You may stop using the Service at any time. Sections that by their nature should survive termination (including Disclaimers, Limitation of Liability, Indemnification, and Governing Law) will survive.

16. Apple App Store Provisions

The following applies to your use of the iOS application:

  • These Terms are between you and Mizrahi Diamond, not with Apple Inc. Apple is not responsible for the iOS application or its content.
  • Apple has no obligation to provide maintenance or support for the iOS application. Any maintenance and support is solely our responsibility.
  • In the event of any failure of the iOS application to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any). Apple has no other warranty obligation with respect to the iOS application.
  • We, not Apple, are responsible for addressing any claims relating to the iOS application, including product liability claims, claims that the iOS application fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer-protection or similar legislation.
  • In the event of any third-party claim that the iOS application or your use infringes that third party's intellectual-property rights, we, not Apple, are responsible for the investigation, defense, settlement, and discharge of that claim.
  • You represent and warrant that you are not located in a country subject to a U.S. Government embargo, or that has been designated as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties.
  • Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple has the right (and is deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

17. Governing Law and Disputes

These Terms are governed by the laws of the State of California, U.S.A., without regard to its conflict-of-laws principles. Any dispute arising out of or relating to these Terms or the Service will be resolved exclusively in the state or federal courts located in Los Angeles County, California, and you consent to personal jurisdiction and venue in those courts.

18. Severability and Entire Agreement

If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions will remain in full force. These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the Service.
