What if your diamond ring could tell you when someone important messaged—without a buzz, ping, or screen? That’s exactly what SPKTRL, a new French luxury technology maison, has unveiled with its debut product: a high-jewellery ring that silently lights up in colour to deliver essential digital signals, while leaving the noise behind.
Founded by Katia de Lasteyrie, a former innovation leader for LVMH’s Watches & Jewellery division, SPKTRL has officially launched with a bold vision: to redefine wearable tech through a luxury-first lens. Its first release, a screenless diamond ring, marks the beginning of what some are calling high jewellery’s “smartwatch moment.”

But this isn’t another gadget dressed up in gold. SPKTRL’s ring is visually indistinguishable from a traditional Place Vendôme masterpiece. Nestled at its centre is a CVD lab-grown diamond—optically flawless, yet uniquely embedded with proprietary technology that allows it to light up in personalized colours based on the wearer’s preferences.
Imagine: a soft blue glow for a loved one’s text. A flash of magenta for a mission-critical work alert. Everything else? Silenced.
This diamond does not buzz. It does not flash garish lights or vibrate on your finger. Instead, SPKTRL’s wearable is a quiet companion in a noisy digital world—one that blends material craftsmanship with minimal tech to preserve attention and aesthetic integrity.

A New Language of Luxury: The Diamond as Interface
At the heart of SPKTRL’s technology is a striking paradox: complex innovation hidden in simplicity. Powered by a discreet chip and controlled through a minimalist app, the ring gives wearers complete control over which messages warrant a light cue—and which can wait.
Each diamond is colourless and precision-grown using chemical vapour deposition (CVD)—the same technique used to produce quantum-grade diamonds in deep-tech industries. These are not plastic simulants, but real diamonds with ethical and technical pedigree, chosen for both performance and symbolism.
The result? A ring that communicates through colour, keeping the wearer in tune with their world, without interrupting it.

From Smartwatch to Smartstone: Reclaiming Time in Style
SPKTRL represents a subtle yet radical shift in how luxury clients engage with technology. Unlike mass-market wearables that demand constant attention, SPKTRL’s diamond ring honours time as the ultimate luxury. It appeals to a clientele fluent in technology, but uninterested in being tethered to it.
With pre-orders opening in Q3 2025, the ring will be released to a limited group of jewellers, elevating its allure among collectors, design-forward technologists, and mindful luxury seekers alike.
For de Lasteyrie, SPKTRL is the culmination of nearly two decades exploring the intersection of emotional design, jewellery heritage, and functional innovation.
“Our technology isn’t designed to replace your phone or make you faster,” she explains. “It’s designed to give you back control. The stone is the interface. The colour is the language.”

The Future of Quiet Luxury Is Here
As the luxury industry reckons with growing digital fatigue, SPKTRL offers a refined path forward: one where jewellery doesn’t just decorate—it enhances clarity. In the same way that the smartwatch revolutionized timekeeping, this screenless diamond ring may herald a new era for jewellery: where design leads, and tech disappears.
For those who seek less input and more intention, SPKTRL’s launch marks the dawn of a new art de vivre—where elegance meets presence, and your most important moments shine through in light, not noise.
