Hi FHB, the Diamond white you have is a large-chip pattern reconstituted stone. If it is of any help in seeing images of this type, then Caesarstone have a similar looking stone style in their range called Nougat 6600 and on their web page for this they have lots of kitchen images which have used this Nougat 6600 material. Their site link is here.
Quantum Quartz also have a Galaxy Black similar to your Diamond Black and on their website they don't have many kitchen images but they do have a kitchen visualizer page that will allow you to load up the Galaxy Black into a preset kitchen image.
