Spktrl’s AI diamond ring aims to cut screen time

France – Parisian start-up Spktrl is reimagining wearable technology with the launch of its AI-powered Light Ring, a piece of fine jewellery designed to curb screen time. Set with a 1.5-carat colourless lab-grown diamond, the ring discreetly filters smartphone notifications, only lighting up for urgent messages.

Founded by Katia de Lasteyrie, former innovation lead at LVMH, Spktrl positions itself at the intersection of luxury and digital wellbeing and offers what de Lasteyrie calls ‘quiet tech’ – technology that refines attention rather than demanding it.

The ring uses a self-learning AI model to adapt notifications by colour, rhythm and brightness – with green signalling work, blue for family and purple for social contacts. Positioned as a tool for modern digital detoxes, it remains inactive most of the time so that users check their phones only when necessary.
