How current are these prices?
The prices in the table above were last captured from public retailer listings on September 17, 2026 (September 2026 collection cycle). In the October 24, 2026 (October 2026) collection this certificate was not found at two or more tracked retailers, so no current comparison is shown. Retailers reprice and delist stones continuously, so any listing shown here may have sold, been delisted, or changed price since capture.
