Signal history

Beth Tamara Gerstein: trading record in brief

Beth Tamara Gerstein is a declared insider of Brilliant Earth Group, Inc. (chief executive), with filings sourced from SEC (Form 4). The record holds 25 filings, for trades running from 27 September 2021 to 19 August 2026.

Both buying and selling appear: 2 purchases worth €11k, against 10 sales worth €4.5M. Netting one side against the other leaves €4.5M of net selling. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. 2026 to date brings 2 purchases and no sales.

Most recently, on 19 August 2026, the filings show an open-market purchase worth €7,333 in Brilliant Earth Group, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. US insiders must file a Form 4 within two business days of a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
