Martin Katz Unveils Energia della Vita Jewels Honoring Tuscan Sculptor Andrea Roggi

“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,” Martin Katz said as he unveiled Energia della Vita at Galeries Bartoux, 5 Avenue Matignon, in Paris. The limited-edition jewelry series was presented as part of Andrea Roggi – 50 Years of Creation, Roggi’s first Paris retrospective running February 13–March 8, 2026.

The origins of Energia della Vita trace back to 2023, when Andrea Roggi unveiled a monumental bronze in the Salone dei Cinquecento at Palazzo Vecchio in Florence crowned with a luminous jeweled sphere conceived by Katz. Roggi’s bronze was cast using lost-wax techniques and finished with dynamic molding and fire patination; the bronze-and-sphere assembly later traveled to Paris for exhibition at Hôtel de Crillon in 2025, where jewelry and sculpture were shown together.

The original Katz sphere offers a technical ledger of intent: crafted in 18k white gold, the piece required two months of meticulous work and was set with nearly 2,000 precious stones secured by more than 8,000 setting points. The gem palette for that first sphere included blue sapphires, Paraíba tourmalines, tsavorite garnets, and white diamonds, a constellation of materials that translated Roggi’s monumental form into refracted light on a micro scale. Katz described each jeweled sphere in the limited collection as “a microcosm of cosmic energy.”

Energia della Vita extends that experiment into wearable jewel forms conceived as small, relief-worked spheres that echo Roggi’s Tree of Life vocabulary. The retrospective at Galeries Bartoux charts Roggi’s five-decade practice through paintings, drawings, sculptures, and archival materials, and the jewelry appears within that curatorial frame as an effort to make the sculpture’s life-force portable and intimate, stones functioning as concentrated light atop miniature, textured orbs.

Katz’s wider 2026 calendar reinforces the atelier’s one-of-a-kind focus. Martin Katz will present one-of-a-kind creations at L’Amusette, a salon-style pavilion produced by Concept Privé at the Naples Sailing & Yacht Club from February 22–25, 2026; the Pavilion opens Sunday, February 22, with an evening reception and a live performance by Lilit Sarkissian. The Martin Katz curated-collection pages note that each Katz piece is either one-of-a-kind or produced in limited edition and is “meticulously signed and numbered,” and the brand site credits photography to Oliver Borde.

Several commercial and technical details remain to be confirmed: Katz has not disclosed the edition size or per-piece specifications, retail pricing, or sales channels for the Energia della Vita series, nor have sourcing or certification details for Paraíba, tsavorite, sapphires, and diamonds been released. For now, Energia della Vita stands in Paris through March 8, 2026 as a rare public moment where Tuscan monumentality and Beverly Hills high jewelry meet at the scale of a jeweled sphere.
