A pic of work-in-progress, paving cobbles for pathway for a residential society.

Not sure if the picture gives you an exact idea of the color of these cobbles. They are brown. In the language of stone, brown may be slightly different from what one understands in other contexts.

Size: 150 mm * 150 mm on the surface side, thickness 40 to 60 mm.

Somewhat similar to cobblestones are flagstones; they are mostly irregularly shaped and have bigger surface area. If someone attempts flagstone flooring indoors, should make that space ever-attractive.
