You can find Finland's most interesting rings at the Caratia online store. Finland had a thriving goldsmith industry in the 1950s-70s. The selection includes many discontinued models. Each ring is cleaned and any engravings are removed. All jewelry is thoroughly inspected. Older pieces are intentionally left with a time-worn patina. Newer models are cleaned more thoroughly and are often like new. You can find the most interesting sold-out rings in the Jewelry Archive.
