Crystal AB is a clear crystal with an iridescent ‘aurora borealis’ coating that makes it reflect different colours as the crystal moves. It’s the mainstay for sparkle and works well on any colour. Magpie sew-on crystals are AAAAA grade top quality crystals with a slight bevel edge, flat back and two small holes for stitching in place. The sparkle of these crystals is unbeatable. Small navette = 6 x 12mm
