Puzzle rings are such a unique addition to any ring stack! They are wonderful for those who like to keep their hands busy, enjoy a little challenge, or just appreciate the design. These puzzle rings in particular are comprised of 6 interlocking bands that come together to make a woven design. This style has 2 inner bands that create an X in the center and 4 outer bands (2 sets of 2) that weave in and out of the X. They are made of sterling silver and, depending on the size, weigh between 5.48 - 6.13 grams. They currently come in sizes 6.5, 7, and 7.5. At its thinnest point, also dependent on the size, the bands measure between 4.4mm and 4.6mm thick. If you have an affinity for unique jewelry, a puzzle ring might just be the perfect addition to your collection!
