23rd April 2025: London, United Kingdom – Jewelex, a revered name in fine diamond jewelry, and Ultrahuman, a pioneer in wearable technology, have come together to combine time-honored craftsmanship legacy with cutting-edge health technology with Ultrahuman Rare, the world’s first luxury smart ring.

At the heart of Rare lies a profound respect for artistry and precision. Jewelex, with a heritage spanning over 59 years, has continually set new benchmarks in diamond and jewelry craftsmanship. Their legacy is defined by innovation, where advanced metalworking techniques enhance traditional artistry, ensuring exceptional detail and consistency in every creation.

Rare embodies the seamless fusion of meticulous craftsmanship and precision engineering. Leveraging cutting-edge CNC machining, the ring’s intricate design is executed with micron-level accuracy. While machines deliver exacting precision, the final touch is entrusted to skilled artisans – who then polish and refine each piece to ensure warmth, character, and the unmistakable essence of true craftsmanship.

Jewelex integrates sustainability into every facet of its Rare’s manufacturing, operating on 100% renewable energy since January 2023. Rainwater harvesting at its corporate headquarters further supports resource conservation. By continuously investing in clean energy and eco-friendly practices, it reaffirms its commitment to a greener future in fine jewelry.

On the other end of this union, Ultrahuman has reimagined wearable technology through its mission of health optimization. From the world’s lightest sleep-tracking wearable, the Ultrahuman Ring AIR, to the advanced Ultrahuman M1 continuous glucose monitoring platform and the revolutionary Ultrahuman Home health monitoring device, the company has been at the forefront of turning health data into actionable intelligence.

Ultrahuman Rare was unveiled at the world’s premier technology event, Consumer Electronics Show (CES) 2025 in Las Vegas, marking a defining moment in the evolution of fine jewelry.

Rare launched with the “Desert Collection”, featuring three distinctive designs: Desert Rose, Dune, and Desert Snow. Inspired by nature’s most captivating landscapes, these pieces reflect the fluid elegance of wind-sculpted dunes, embodying the balance of beauty and resilience found in arid terrains.

• Dune and Desert Rose rings are meticulously crafted from 18K Gold, sourced exclusively from London Bullion Market Association (LBMA)-approved refineries and hallmarked by the Bureau of Indian Standards (BIS), ensuring the highest standards of authenticity and quality.

• Desert Snow is engineered from Pt950 platinum, a metal renowned for its rarity and prestige. 

Commenting on the partnership, Bobby Kothari, Jewelry CEO, Jewelex India Pvt Ltd, stated, “The power of collaboration lies in the ability to bring together diverse strengths. This partnership demonstrates that when traditionally separate industries unite, the potential for growth and innovation is limitless. This is a prime example of how cross-industry synergy can redefine consumer experiences.”

Each Rare ring begins its journey in Jewelex’s expert hands before making its way to UltraFactory, Ultrahuman’s advanced manufacturing facilities in Plano, Texas, and Bengaluru, India.

Here, the skilled artisan-crafted fine jewellery is transformed through intricate manufacturing processes into Rare.

Precision-engineered PCBs, 6-axis motion sensors, and medical-grade temperature sensors are meticulously integrated into the ring’s structure. A proprietary resin casting process ensures seamless embedding of technology while maintaining the aesthetic integrity of the jewelry. Each ring, available in sizes 5 to 14, undergoes extensive testing and multiple rounds of quality control, ensuring impeccable performance and craftsmanship.

Finally, Ultrahuman’s custom-programmed firmware is updated on Rare. These firmware updates are designed to be seamless, ensuring that Rare continuously evolves through adaptive software that’s unique.

Mohit Kumar, Founder & CEO, Ultrahuman, added, “Our collaboration with Jewelex brings together two worlds: their legacy of craftsmanship and our expertise in cutting-edge health technology, redefining fine jewelry in the age of wearables. 

With Rare, we’re catering to individuals who want their health journey to be as elegant and meaningful as the rest of their lives. The possibilities ahead are limitless.”

Rare made its grand debut in two iconic capitals of luxury: Paris and London.

• Selfridges London, an emblem of modern luxury, is where heritage and innovation converge to redefine the retail experience.

• Printemps Paris, with its Belle Époque grandeur, embodies the spirit of Parisian chic through its exquisite curation of global luxury.

Rare’s perfect blend of heritage and future brings the world a statement of sophistication, where old-world artistry meets the future of wearable intelligence, offering an unparalleled experience of beauty, craftsmanship, and technology.
