The Ooolala! necklace set, designed by Gabriela and Karina Iskin, Argentina, is a personal favorite. The Iskin sisters specialize in using unconventional materials in their jewelry designs, such as acrylic, stainless steel, anodized aluminum, and leather. Ooolala! consists of a necklace of silver rings in 3 sizes with 4 detachable links. These detachable links can be used for inserting one or more of 5 different colored anodized aluminum discs, for taking apart and designing earrings, linking up the rings into different shaped necklaces or bracelets...the options are endless. The Iskin sister's designs have been featured in the MoMA Design Store and are found in design and museum shops around the world.
