SICIS: The Alchemy of Eternal Paintings and the Resurrection of Micro-Mosaic

In the quiet, historic streets of Ravenna, Italy, the walls of Byzantine churches whisper stories of eternity. Here, mosaics are not merely decoration; they are “eternal paintings,” surfaces where light dances across stone and glass, preserving narratives for centuries with an imperishable vibrancy. It was this ancient heritage that Maurizio Placuzzi sought to channel forty years ago when a member of the Saudi royal family approached him with a singular vision: to clothe a palace in the most luxurious of textures.

Placuzzi, inspired by the glimmering heritage of his hometown, presented the Sheikh with small mosaic souvenirs—fragments of Ravenna’s soul. The concept resonated instantly. Yet, the transition from a souvenir to an architectural skin revealed a significant void in modern craftsmanship. The industrial capacity to produce mosaics had all but vanished, strangled by the sheer difficulty and slowness of the traditional method, which required artisans to apply tesserae—small blocks of stone or glass—directly onto walls, one by one, on-site.

To bridge the gap between ancient artistry and modern demand, Placuzzi had to reinvent the process. He developed the “double indirect method,” a technique that allowed the creation of mosaics to be transferred from the scaffolding to the atelier. This innovation led to the founding of SICIS, a workshop where artisans could handcraft mosaics panel by panel, metre by metre, in a controlled environment.

Once crafted with the precision of a painting, these sections are assembled like a grand puzzle within the client’s space, allowing the ancient aesthetic to scale at a pace previously unimaginable. “From nothing, my father built a business out of his passion, which is now part of my family’s DNA,” reflects Gioia Placuzzi, Maurizio’s daughter, who now carries this legacy into a new dimension as the creative director of the SICIS jewelry branch.

The Shift from Wall to Wrist

While the atelier successfully revived the architectural mosaic, gracing the interiors of hotels, yachts, and estates, the ambition of SICIS eventually turned toward the intimate. The philosophy was simple yet profound: if a tessera creates majesty on a wall, its miniaturization could evoke intimacy on the body. This pursuit marked the revival of the long-lost art of the micro-mosaic.

“There’s no limit to the size of a tessera,” Gioia observes. “It can be big on a wall or as small as you can imagine on jewelry.”

The transition required a return to 18th-century methodologies, a time when nobles and royals wore mosaics as wearable grand tour souvenirs. However, the technique had largely faded into obscurity by the 20th century. It took SICIS five years of rigorous research and experimentation to reclaim this forgotten virtuosity, eventually establishing a standard of craftsmanship that led to partnerships with high-jewelry houses like Harry Winston and cultural institutions like the Vatican.

The process of creating a micro-mosaic is a feat of patience and thermal chemistry. It begins with Venetian glass, melted and pulled into long, impossibly thin rods—some merely a millimeter thick. These rods, known as “spun enamel,” hold the chromatic DNA of the final piece.

Once cooled, the glass filaments are fractured into hundreds of tiny fragments. These are not merely tiles; they are the brushstrokes of a solid painting. An artisan must then delicately place each speck, piece by piece, into a bezel or frame. The result is an image that possesses the durability of stone but the fluidity of a watercolor painting.

Chromatic Depth and the Malmischiati Technique

To truly replicate the nuance of painting, SICIS realized that standard glass colors were insufficient. They developed the malmischiati technique—literally “badly mixed” or “mixed”—which involves blending various colors within a single tessera rod. This deliberate imperfection creates a nearly infinite spectrum of shades, allowing for gradients and textures that flat color could never achieve.

The result is jewelry that breathes. The tesserae do not just sit beside each other; they interact, creating depth and luminescence. This technical mastery is perhaps most visible in the Quetzal collection, a series born from a moment of awe in the Amazon rainforest.

During her travels, Gioia was captivated by the quetzal bird, a creature defined by its radiating plumage of red, aquamarine, and blue. “I fell in love with its beauty,” she recalls. “Just imagine the birds flying. I wanted to recreate the same lightness, the same soul of the bird.”

The challenge was to capture not just the color, but the iridescence and movement of the feathers. To achieve this, the micro-mosaic work was paired with titanium and gold. The inclusion of titanium provided a structural lightness and a unique luster that mirrored the joyful, sparkling spirit of the bird in flight.

Through these creations, SICIS asserts that the mosaic is not a static relic of the Byzantine era, but a living medium. Whether spanning the vaulted ceiling of a palace or resting against the pulse of a wrist, the arrangement of glass and stone remains a testament to the human desire to build eternity out of fragments. “Innovative design,” as Gioia notes, “is the star of our sky.”
