About this library
25hours is an independent sterling silver jewelry brand — we design and sell S925 sterling silver pieces. These eight references are a contribution to the silver jewelry field, compiled from published and primary sources and shared openly. We are not a research institution or an educational organization and do not claim to be one. This is a brand-published open reference, and we hope it is useful.
These pages are open references, not marketing in disguise:
- No product links, no affiliate tracking, no email capture.
- External links point to primary sources (assay offices, certification bodies, government agencies) — not to us.
- Comparisons and ethics content are written to be descriptive, not persuasive.
- Brand presence is limited to the 25HOURS mark at the top, a share QR, and this acknowledgment — intentionally minimal so the references can stand on their own.
