Very, very sparkly!
One of the sparkliest products I've ever used. I like to wear it lightly dusted over other eyeshadows or layered for a disco ball effect on my eyelids. A little goes a very long way and the slightest amount will make a huge difference. It reminds me of Make Up For Ever's Diamond Powder in a way. They're quite different in form and color, but have similar effects and usage.
