An artefact.
A story.
A lasting link.
Natural stones, made personal. Digital passports, made verifiable. A physical object and its story — connected, wherever they go.
Explore the first passport
Not just a bracelet.
Your own constellation.
Choose the stones that speak to you. Shape their rhythm, colour and meaning — on your own, or together with a maker.
Our online atelier begins with natural-stone bracelets: 8 and 10 mm beads, a personal composition and a fit made for your wrist. Personal symbolism is part of the story, not a scientific claim.

The object stays tangible.
Its story becomes portable.
A digital passport records an artefact’s composition, its known history and the evidence behind it. An Ethereum NFT can anchor the fingerprint of that exact record — without locking the passport into one website.
Record
A structured, versioned JSON passport. Public object data only; private owner data stays out.
Fingerprint
A SHA-256 hash of its canonical form. Change the content, and the fingerprint changes.
Anchor
A transferable Ethereum NFT holding that hash. Storage can move; the committed record remains identifiable.
A hash proves a match to a record, not the truth of every claim inside it. An NFT is not a gemological certificate or, by itself, proof of legal ownership of the physical artefact.
Meet the first artefact.
A real bracelet, an inspectable record. Explore each stone, download the document, and check its fingerprint yourself.
Black agate
Select a numbered stone to read its record.
Numbering starts with the black agate and runs clockwise. Colours are illustrative; names are maker-reported, not laboratory verified.

This digest is calculated from the downloadable passport, not retrieved from an NFT.
Check the passport.
Verify this example, or choose a downloaded copy. Everything runs in your browser; your file is not uploaded.
For the curious: what exactly is being verified?
The passport uses a restricted, deterministic JSON canonicalization profile: sorted object keys, preserved array order, UTF-8, no insignificant whitespace. SHA-256 is calculated over those bytes. Reformatting the JSON does not change its canonical fingerprint. The manifest, file locations and NFT status are outside the hashed payload.
This page compares your file with the example manifest served by this same website. It is not yet an independent on-chain verification. After a Mainnet mint, verify the digest against the NFT contract as a separate source of trust.
One passport.
More than one home.
You should be able to keep the record even when a website changes. The same passport can be copied and verified wherever it is stored.
Find your stone.
Give its story a future.
We’re building the atelier and the passport together. Come back on 1 December to explore the first collection and create an artefact of your own.
