Kind of want to keep them the size they are for decorative purposes.Break the rocks into smaller rocks.
Drill a 3/8-hole about 6-inches deep.
Fill it with silly putty.
Cover the thing with some old carpet
Take 32-caliber Ram-Set, with the heaviest charge, and longest pin they make.
Center the Ram-Set on the hole full of silly putty, and give it a good smack.
The hydraulic pressure will split the rock.
Traditionally, a ”Stone Sled” was made with two lengths of 4X6, with the fronts tapered up, and the whole length faced with 1/4-inch steel strap. You then put 2X cross pieces over the 4X6s to make a deck. Two hole were drilled near the front of the runners, to attach towing ropes or chains.
I think you could find actual plans for one in the plan archives of the Agg Engineering Schools, at the Land Grant Universities. They are a good resource for farm related designs, for everything from barns, sheds, houses, and chicken coops and implements.
