Strata is part of the SGRAFFITO collection. The shape of these long bars permits a gradual gradient of color: aqua, blue, dark blue. Of the two styles available, mini-bars are the lightest earrings produced by MOMO Glassworks! The ear wires are argentium silver (nickel-free, slow tarnish) and come with silicone ear backs included. (please note that slight variations from the photographed item are inevitable due to the nature of this work -- each design is hand-painted)
