I’ve written on how still photography can’t capture sparkle. (internal link) Rolf Luetke comes close (external link) , though, in this slightly blurry photo of crystals showing striations.

There are also swirls in the photo as light plays off varied crystal faces. I’ve noticed in my photography that a sparkle diminishes as the lens focuses. A pleasing spot of light changes into a single, sharp point. The blur shown above helps depict movement, still the key element to letting sparkles shine.
