Kymi is a jewelry collection by goldsmith Tero Hannonen. The pieces are crafted from 18K white gold, yellow gold, and 950 platinum with sapphires or diamonds. The first Kymi ring was designed under the theme "The New Beginning." Tero wanted the ring to embody the idea of a lifelong journey.

"A river often symbolizes life. It has a beginning and an end. Both in the river and in life, there are sometimes gentle and peaceful waters where the pace slows down. Then the journey continues again and the stream happily flows between the rocks."

The Kymi ring was nominated as a finalist in the "Most Beautiful Ring of the Year 2022" competition. Since then, the design has grown into a beautiful collection of earrings, necklaces, and rings — available in various widths and gemstone colors. The Kymi collection is unisex, making these pieces suitable for everyone.
