IKO is a stained glass studio based in central Italy specializing in custom designed panels for homes and religious buildings, as well as intensive and residential courses for beginners or professionals.
At IKO Studio, we bring the elegance of decorative glass to life, crafting unique pieces that cater to every style—whether classic or modern, sacred or contemporary. Driven by passion we create stunning works that blend tradition with contemporary design.
Our glass pieces, crafted with exceptional skill and meticulous attention to detail, are perfect for enhancing windows, doors, sliding doors, internal partitions, skylights, and backlit ceilings.
Our dedication goes beyond traditional panels; we create intricate, personalized designs tailored to every taste and crafted with the highest professionalism. In addition, we offer a selection of custom wall lights, ceiling fixtures, and special keepsakes for celebrating life’s memorable moments, such as weddings and births.
IKO Studio’s glass artworks are made using the finest colored glass available on the market, enriched by our expertise in painting with the traditional grisaille technique. Our meticulous attention to detail makes each piece visually striking from a distance and remarkably precise up close. Each layer of paint is applied with specially selected pigments, enamels, and silver stains, then fired at high temperatures to ensure long-lasting durability.
The studio was founded in Rome by artist Diego Tolomelli, who, after over ten years of experience in renowned glass studios in the United Kingdom, chose to return to Italy. Following two years of collaboration with a historic Roman workshop, he decided to pursue an independent path. In 2007, he established IKO Studio, drawing on his expertise and best practices to create unique, high-quality work. His mission is to produce pieces of the finest quality, where the art of glass reaches its most refined and perfect expression.
IKO Studio collaborates with architects and interior designers to create high-quality glass panels for churches, public buildings, hotels, and private homes, both in Italy and abroad. Our experience enables us to provide bespoke products, delivered on time and always within the agreed budget.
Located in the historic heart of the medieval town of Bolsena, along the shores of Europe’s largest volcanic lake, our studio is a fascinating stop for those who appreciate art, history, and nature. Come and visit us to explore our exhibition space and learn more about our work.

For me, the magic of stained glass comes from the way in which coloured glass becomes transformed by light, the way in which the tiny bubbles trapped within the glass, give it movement and sparkle. The magic becomes complete once paint is applied to the glass, creating delicate shading, subduing the light in places whilst highlighting it in others. This art form is unique. It has transparency within its soul and this becomes glorious and radiant with light.
