CULTURED: A white gold ring with diamond accents and NFC-embedded Momento Pearl.

US jeweller Galatea has unveiled Momento Pearl, a cultured pearl that contains an NFC chip. Using an accompanying NFC app, “the user records a message or uploads an audio file,” the jeweller explains. “By tapping the pearl against an NFC-enabled mobile device, the audio is played and other digital material displayed.”

Galatea plans to introduce more NFC-enabled jewelry including gemstones and diamonds over the coming months.
