Jewelry, Eyewear and Watch Design Tonos Ring by Elena Kapompasopoulou 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.
