Tonos is a limited edition handmade ring consisted of two materials with diverse properties. A 14 karat gold cylindrical core interlocks with an external layer of grey concrete. Tonos is a punctuation mark specifying the correct pronunciation of a word. Driven by the actual use in Modern Greek language, the name is used in a metaphoric way. The projected segment of the gold core is intentionally employed to emphasize the transition of the materials and balances the shiny and matt side of the object. Each piece is unique, numbered and available in a variety of precious metals and colors.

Motivated by cement’s prominently characteristics and properties, the architect Elena Kapompasopoulou employs innovative design and fabrication techniques to disrupt the conventional bond between concrete and architecture, and familiarize the human body with a material used until now only for construction purposes. Her brand Cement Chemistry, launched in 2014, focuses on the unique applicability of concrete as a malleable resource for architectural jewelry design, and brings to life handmade, limited edition jewelry, inspired by raw materiality and geometry - available in bold shapes and colours.
