Your finest objects deserve better than a drawer
Jewelry, watches, artworks, cars, silverware. Collection brings together your pieces, their proofs and their memories in one private place, and prepares their transmission. Photograph a piece: it fills itself in.
Public Preview. Free for up to three pieces, no card required.

What you own has a story. Today, it is slipping away.
The certificate sleeps in a drawer, the invoice in a mailbox, the provenance in your memory. A piece without its story is worth half of what it is. And when the day comes, your loved ones inherit the objects, not what gave them meaning.
Collection ties that thread back together, in a place that is yours.
Concrete, from the very first piece.
Photograph a piece: the app recognises the brand, model and year, and pre-fills its record. Add certificates and invoices. From jewelry to cars, each category has its own fields.
Attach to each piece memories in photo, text, voice or video. The who, the when, the emotion. What you know about the piece no longer lives only in your head.
A record of events, service, appraisal, exhibition, restoration, each with its trust level. The Maison or the workshop can counter-sign it. Documented provenance is value.
Track the estimated value of your pieces over time, and export a full insurance dossier. You know what you own, and you can prove it.
Entrust a piece or a gallery to a loved one, an expert or an insurer, read-only or contributor, through a private, revocable link. Everything is private by default.
Pass a piece to an heir, or gather a family circle of up to six loved ones. The piece travels with all its memory, documents and stories intact.
One day, your loved ones will not inherit an object. They will inherit its story.
Case
The écrin that keeps the memory of what it protects.
Do you own a watch or jewelry box signed by an Eternall écrin? One tap on the chip, and the écrin reveals the pieces it holds and their stories.
