Our SWAROVSKI ELEMENTS chessboard cut crystal rhinestone is a design masterpiece. This gorgeous piece in a geometric square is shaped for maximum sparkle. Aquamarine is a bright choice of color because it brings to mind the element of water, which adds a clean fresh shimmer to your accessories. Please note that when using flatbacks, you should never use a glue gun or super glue (cyanoacrylate) as they will damage the foil backing on the rhinestones. Also be aware that while flatbacks are terrific for adding sparkle to clothing they should never be dry cleaned. Please follow the cleaning care instructions on your glue; many glues require that clothing be air-dried. If you do machine dry always turn the article inside out before being placed in the dryer to avoid damage.
