After notching up 30 years of jewellery-making and gemmology expertise separately, Walter Costantini and Marco Valentini opened Kryos together in 2017. The atelier is located in cosy Campo San Tomà, and is housed in the historic headquarters of Gioielleria Sfriso, which for over a century was the only silver factory in Venice. Walter and Marco opted for a renovation that kept the original buildings intact, creating a workspace full of space and light.

Together, they work as a team, crafting jewellery in gold, silver and other metals with settings that enhance the jewellery with gemstones and one-of-a-kind workmanship. Walter and Marco offer a bespoke service. More recently, they started offering workshops to craft your own ring out of metal under their guidance.
