SellDiamonds ("we", "us") operates brilliantbuyback.com as a neutral comparison platform. We do not buy diamonds ourselves — we forward quote requests to professional national diamond buyers. This page explains what information we collect and what we do with it.
What we collect
- Quote details you voluntarily submit: name, email, phone, ZIP, and information about the diamond or jewelry you want to sell (carat, shape, certification, photos).
- Contact messages you send through the contact form.
- Basic technical data your browser sends automatically (IP, user agent, referrer) used for security and aggregate analytics.
How we use it
- To forward your quote request to vetted professional diamond buyers so they can make you an offer.
- To reply to your questions.
- To improve the website and detect abuse.
We do not sell your personal information. We share quote details only with the buyers needed to fulfill your request.
Cookies
We use only essential cookies needed for the site to function. We do not run advertising trackers.
Your rights
You can request access to, correction of, or deletion of the personal information we hold about you at any time by writing to us via the contact page. We will respond within 30 days.
Data retention
Quote requests are retained for up to 24 months so buyers can follow up on open offers, after which they are deleted or anonymized.
