Landscaping is done to beautify the outdoors. So why use regular stones if there are decorative stones at hand? It wouldn’t be everyday that these stones have to be installed outdoors but once they are installed, they can already beautify the outdoors forever.
Besides being more beautiful, decorative stones also perform other important functions like keeping the soil together, supporting plants, strengthening driveways, and giving a nice border on the pavement or patio. Regular stones can do all these, too. But they can never provide function and fashion in one like decorative stones do.
