Carlos Perez used a diamond polishing machine on his demo.
The lacy whitish features are sea shells cut into 3/8-in. slices.
Perez used stencils to create an unusual diamond polished overlay.
To achieve the finished look involved stencils, colored concrete, and sea shells diamond polished to a 3000-grit finish.
Take a closer look at the finished project.
The detailed look of the polished sea shells are complemented the tan overlay concrete.
