Original Swarovski®- crystals of high quality leaded glass.The crystals split light into the colour spectrum when hung in a sunny window casting a number of shifting small rainbow patterns on the walls. This playing with sunlight lends itself well for a mobile for hanging over a cot as present for a baby. Some of the crystals are mirrored and marked as AB.Similarly shaped but somewhat differently polished are other glass objects which are simpler, lead free and somewhat cheaper. Theses are marked as BF.
