Not a gem-like as you might think
While this does read as multiple facets of real diamonds in the sample picture, it's not really that way in person. This design is more wedges and pieces of diamonds collaged together with some computer magic... as a result at real size you can see the collage elements. That said, this paper still says diamonds just in a more abstract sense. Zoom in on the photo. This paper might work for you and might not.
