See it in the yard.
Honeycomb earns its name. This limestone comes from ancient sea beds, and marine life left it riddled with holes. The result is a rock full of pockets, tunnels and texture. It is a favorite for aquariums, and it is just as interesting as a garden accent. Every piece has a different pattern of holes, so plan to sort through the pile and pick the shapes you like.
Limestone shaped by the sea
The holes in Honeycomb were formed by marine life in ancient sea beds. That history is what gives the stone its open, lacy structure.
Turn a piece over in your hands and you will find openings on every side. Some pieces are more open than others, which is part of the fun of choosing.
A natural for aquariums
Honeycomb is great for aquariums. The holes give a tank depth and plenty of places to tuck into.
Bring the inside measurements of your tank so you can choose pieces that fit. Tell staff about your setup and they will help you pick.

Stone is sold by weight, so you can buy a few hand-picked pieces or a larger amount. Visit 5300 Excelsior Road and choose your own.
