Privacy Policy

Effective date: August 26, 2026

This Privacy Policy explains how HST Lab-Grown Diamond Jewelry (“HST Jewelry”, “we”, “us” or “our”) collects, uses and protects personal information when you visit hstjewelry.com, submit an inquiry, contact us through WhatsApp, or complete one of our social-media lead forms.

We are a China-based manufacturer of lab-grown diamond jewelry serving wholesalers, jewelry brands and designers worldwide.

1. Information we collect

We collect the information you choose to provide to us, including your name, company name, business email address, telephone or WhatsApp number, country, product interests, estimated quantity, design references and messages.

When you submit a Facebook or Instagram lead form, we may receive the contact details and responses you submit through that form. Our website may also receive basic technical information needed to operate securely, such as browser type and server logs.

2. How we use information

We use your information to:

reply to inquiries and prepare product quotations;
discuss custom designs, samples, production and delivery;
provide customer service and manage business relationships;
protect our website and prevent fraud or misuse; and
meet applicable legal, accounting and record-keeping obligations.

We will only send marketing communications where permitted by law or where you have given the required consent. You can ask us to stop marketing communications at any time.

3. How we share information

We do not sell or rent your personal information. We may share information only when necessary to provide our services—for example, with communications, payment, logistics or IT service providers—or where required by law. Those parties may use the information only for the relevant service or legal purpose.

4. International processing

HST Jewelry operates from China and serves customers internationally. By contacting us, you understand that your information may be processed in China and in other countries where our service providers operate. We take reasonable steps to protect information during such processing.

5. Data retention and security

We retain inquiry and order information only for as long as reasonably necessary for the purposes described in this policy, including customer service, business records and legal obligations. We use reasonable administrative and technical safeguards to protect information. No internet transmission or storage method is completely secure, so we cannot guarantee absolute security.

6. Your choices and rights

Depending on applicable law, you may ask to access, correct, delete or restrict the use of your personal information, or to withdraw marketing consent. To make a request, contact us at info@hstjewelry.com. We may need to verify your identity before completing a request.

7. Third-party platforms and links

Our website and communications may link to third-party services, including Facebook, Instagram and WhatsApp. Their collection and use of information are governed by their own privacy policies. We are not responsible for the privacy practices of external websites or platforms.

8. Changes to this policy

We may update this policy when our practices or legal obligations change. The updated version will be posted on this page with a revised effective date.
