How would jewelry that hides a private key work?
Discussion
NFC chips lol
Shamir or Seed XOR will allow you to keep analog and more resistant to physical damage. But I like the idea of some distributed set of rings or something. Maybe ideally something rather subtle than too flashy and appealing to dumb thieves.
I wouldn't trust gold or Jewelry with my seed.
The looters go after that stuff when they rob you.
Jewelry gets stolen.
A disguised Ledger-like device where the PIN is entered by pressing a particular series of beads or links on the jewelry. You'd have to have a PIN (and a complex one) or else you're talking about embedding a bearer asset on something that can easily walk away.
QR code of the private key holographicaly engraphed into a diamond. When you point a laser to one side of the diamond a hologram of the QR code appears in mid air on the other side.
You might take plain glass stones instead of a diamond if you want to add some more sats to the wallet.
NFC tangem is doing it. Not a bitcoin only wallet, but a great idea.
For example, you can buy two cards and a ring, all our backups of your seed phrase. Lose all three and lose your keys.

Have you seen the size of SD cards ?
