Martin Katz Unveils Jewels Celebrating the Creation of Tuscan Sculptor Andrea Roggi February 18, 2026 (0 comments)
PARIS, France--Beverly Hills high jeweler Martin Katz and Tuscan sculptor Andrea Roggi unveiled a limited-edition jewelry series titled, Energia della Vita (Life Energy) at Galeries Bartoux in Paris.
The jewelry collection is presented as part of the exhibition, Andrea Roggi – 50 Years of Creation that will run to March 8 in the gallery at 5 Avenue Matignon.

In harmony with Roggi’s organic bronze forms, Martin Katz says he translated the concept of life force into a new series of jeweled spheres — each described by the jeweler as a microcosm of cosmic energy in the limited collection.
Unveiled during Roggi’s first major retrospective in Paris, the collaboration extends sculpture into the language of high jewelry, translating the artist’s philosophy of vital energy into precious stones.
“The concept I used for the Life Energy series is that the Earth's energy comes from the sun, which we see in the changing color of the sky as it evolves into each season,” Katz said.
Within each jeweled sphere, are pink-blue tones of dawn to luminous midday blues, shifting into the yellows and orange and reds of dusk, before deepening into the midnight horizon returning once more to sunrise. Together, these stones reflect the Earth’s perpetual revolution and the cyclical force that sustains life, Katz said.
Each sphere is handcrafted in:
- 28 grams of gold and set with 87 diamonds (0.54 carats total weight, DEF color, VVS clarity) that were responsibly sourced from South Africa through DTC Botswana.
- 281 colored gemstones (22.99 carats total weight), including blue, violet-blue, violet-pink, pink, orange and yellow sapphires, topaz, and aquamarines
The limited-edition series is available exclusively at Galeries Bartoux Paris during the exhibition period.
The origin of Energia della Vita lies in a work by Roggi unveiled in 2023 in the Salone dei Cinquecento at Palazzo Vecchio in Florence, Italy. Cast in bronze using lost-wax techniques, dynamic molding and fire patination, Roggi’s sculpture was crowned with a luminous jeweled sphere created by Katz.
Crafted in 18k white gold, the original sphere required two months of work and nearly 2,000 precious stones secured by over 8,000 setting points, including blue sapphires, Paraíba tourmalines, tsavorite garnets and white diamonds.
In 2025, the creation was exhibited at Hôtel de Crillon in Paris, where sculpture and high jewelry converged.
Now, in 2026, that collaboration evolves into a limited-edition series — translating Roggi’s philosophy of life energy into an intimate encounter between sculpture and high jewelry, where material and light respond to one another.
