I'm a sucker for the neatness of the square.

Both have their place depending on taste and budget.

Personally I'd be very careful adding stacked stone next to the dark bricks. I think stacked stone can work next to rendered areas to provide contrast/add another element but next to dark bricks it could easily look too busy/too much. It's your home though so do what will make you happy when you drive up to it! If you're dead set on the stacked stone then find the brick manufacturers location and ask to speak to one of their designers for an opinion/options. If they can't help then ask brick manufacturer for the addresses of some properties in your city that have used your particular brick and check a few out. They will usually give you some addresses if you explain what you're trying to do. I'm sorry to have not answered your question as to what colour stacked stone to use. Good luck, exciting times for you.

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. Hope this helps, Malcolm, Compass KItchens
