  • Communicate with you about your requests, updates to orders, or changes to our Services.
  • Send you the CrownStone Journal newsletter if you have subscribed (you may unsubscribe at any time).
  • Comply with legal obligations under Kimberley Process, OECD, anti-money-laundering, and applicable national laws.
  • Detect, prevent, and address fraud, security issues, or misuse of our Services.

4. Sharing & Disclosure

We do not sell, rent, or trade your personal information. We may share information in the following limited circumstances:

  • Service providers: Trusted third parties who assist us with website hosting, email delivery, analytics, or customer support, under confidentiality agreements.
  • Trading and verification partners: When necessary to complete a trade or verify provenance, we may share relevant details with recognised diamond traceability platforms, Kimberley Process authorities, grading laboratories, or logistics partners — with your knowledge and for the specific purpose of the transaction.
  • Legal requirements: Where required by law, regulation, court order, or to protect the rights and safety of CrownStone Diamonds, our users, or the public.

6. Data Security

We implement appropriate technical and organisational measures to protect your personal information from unauthorised access, alteration, disclosure, or destruction. These include access controls, encryption in transit, secure storage, and staff training on data protection.

No method of transmission over the internet is completely secure. While we take your privacy seriously, we cannot guarantee absolute security of information transmitted to or stored on our systems.

7. Cookies & Tracking

Our website uses cookies and similar technologies to enhance your experience, remember your preferences, and gather analytics about how the site is used. You can control cookies through your browser settings. Disabling certain cookies may affect the functionality of the site.

8. Data Retention

We retain personal information only for as long as necessary to fulfil the purposes for which it was collected, including any legal, accounting, or regulatory requirements. Trade enquiry data is retained for the duration of our professional relationship and for a reasonable period afterwards to allow for order updates and verification.

9. International Transfers

Because we trade diamonds sourced from Botswana, Canada, Namibia and South Africa, your information may be transferred to and processed in countries outside your country of residence. Where this happens, we take steps to ensure your information receives an adequate level of protection consistent with this Privacy Policy.

10. Children's Privacy

Our Services are not directed to children under the age of 16, and we do not knowingly collect personal information from children. If you believe we have inadvertently collected information from a child, please contact us so we can take appropriate action.
