The Singelringen was first introduced in Sweden in April 2005 and has since spread to over 20 countries and has become a cult favorite among celebrities. Japan and Brazil have proven to be especially enamoured with the ring. The ring itself is a simple unisex design of sterling silver as a base, which is then layered with a shiny turquoise acrylic. Each ring's interior features a "Made in Sweden" engraving as well as a unique registration number, which you can register to your name on their website where they've formed a community of fellow Singelringens.
