Digital Hallmark
Jewelry Proof of Provenance
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The permanent record for your fine jewelry. Catalogue every piece, pair a Digital Hallmark chip, and prove authenticity and ownership with a tap.
Digital Hallmark turns the heirloom in your jewelry box into a tamper-evident, scannable record. A tiny Digital Hallmark chip fused into the metal links each piece to its passport — read in an instant, with no batteries and no wear.
WHAT IT'S FOR
Whether you're a long-time collector, just inherited a ring you can't quite explain, or walked out of a boutique with a piece that came with a chip, Digital Hallmark gives you one place to keep its full story: photos and video, appraisals and certificates, where it came from, and everyone who has owned it.
THE PASSPORT
Open a piece to see its passport — a clean record of provenance, appraisals and ownership history. Chipped pieces are anchored with a public on-chain proof, so a future buyer can verify them independently. Share a public passport link, or keep any piece completely private.
SCAN & VERIFY
Connect an optional Digital Hallmark UHF reader and scan a piece to confirm it is the original chip, a clone, or a chip that has never been registered. Useful at estate sales, when buying pre-owned, or anywhere you need to ask "is this real?"
TRANSFER & PROTECT
Transfer ownership securely when you sell or gift a piece, or request ownership of a piece you've scanned. Report a piece lost or stolen and get alerted with the time and place if anyone scans it.
OWN THE WHOLE STORY
Add photos, video, voice memos, documents and up to three links to each piece — your grandmother's account of where the ring came from, the auction lot number, the receipt. Search finds pieces by their notes and attached documents too.
PLANS
Start free for your first year. Optional subscription plans — Beginner, Vault, Collector and High Net Worth — add more pieces, chipped pieces and storage, collections, full history and the AI assistant. Subscriptions are billed through your Apple ID, renew automatically unless cancelled at least 24 hours before the end of the period, and can be managed or cancelled anytime in your App Store account settings.
PRIVACY FIRST
We don't track you across apps, we don't sell your data, and there are no ads. Delete your account anytime from Profile → Delete account; after a 30-day grace period everything is permanently erased. Export everything you've recorded from Settings → Account → Export my data.
WHO IT'S FOR
- Collectors who want a record their insurer will recognize
- Heirs and executors settling a jewelry box without a paper trail
- Jewelers who authenticate and hand over pieces with a verifiable history
- Anyone who has ever asked "is this real?"
