SWAROVSKI GEMOTION. Simple and ingenious, Swarovski Gemotion is an outstanding product for setting stones in flexible materials such as leather, or for applying them to movable rails. Thanks to its rivet-like function, designers and manufacturers can create jewelry, eyewear and individual accessories with ease. Gemotion consists of two parts: a mounting, set with a 2mm, 3mm or 4mm genuine gemstone or created stone; and a counterpart, or closure. Both parts are made out of Silver 925. Both parts are connected easily, and permanently, by simply snapping them together.
