Spring cut stone? What does it look like IRL

[chel180]

I was looking around a well known PS vendor and found a selection of Spring cut stones, they were all virtual selections so no useful photos.

I found this information page on them but I was wondering if anyone actually owned one or had a real photo of one? The look rather interesting but I'd never heard of a spring cut before today.
