Nothing Says Everlasting Love Like a Bitcoin Engagement Ring

When considering a proposal, it's important to know the exact worth of the ring before the transaction is made. And with the Bitcoin engagement ring, your smartphone takes the place of a professional jeweler.
The BTC Ring is 3D printed with a QR code that lets anyone with the corresponding app scan your ring to find out the value of its blockchain. The physical ring itself has no value unless you happen to think it's a nice looking piece of jewelry.
