Yes it would be a shame to attach it to a piece of slate and still have it floating around.
You might be able to get it at Home Depot in the garden section. Also check in the flooring and tile section. You may check for broken sections in the cutting area.
Another place to check are garden stores. They often have a broken stone dumping area and you can browse through and get what you need for a fraction of the cost.
