Made in the Czech Republic. These round open glass rings are made from pressed glass. Although no longer in production, we have inventory in a wide variety of colors and treatments. Also known as fisher rings in this size, they are great as links between other design pieces, spacers on a necklace or as accent pieces. Please note that small imperfections will occur as part of the manufacturing process and size, shape and color may vary slightly from lot to lot. Also, since they are no longer in prodution, when theyre gone...they be gone....
