Keystone Shaped Concrete Pavers and Molds by Olde World Stone & Tile

This circle was made with a mixture of 11 each #CS-6531 & #CS-6541 Pavers. The outer circle edge is 38" and the inner circle is 26".
This circle measures 16" inside and 28" edge to edge outside and is made up of 16 individual #CS-6531 Pavers.

This elongated circle is made up of 8 #CS-6541 Pavers and 13 #CS-6541 Pavers. Note that the Keystone Pavers can make a straight line also.

These triangles were made using 12 each of #CS-6531 and #CS-6541 Pavers. The #CS-6531 were used mainly at the corners, and note that the #CS-6541 Pavers were used to make the somewhat straight runs between the corners.

Many designs and unique patterns can be created with these Keystone shaped pavers. The examples below could be used in the garden, around trees, around a small fish pond, or to just highlight an area in the yard. And below are some photos to provide ideas of how you could use 1.5" thick Keystone shaped pavers over a concrete driveway or patio.  The 2.5" thick Pavers can be used for both patio or driveway applications to make circular or curved patterns. 

Part Numbers and Paver Measurements, and How They Relate to Each Other

As is the case with many of our part numbers, they relate directly with the measurements of the mold and/or finished stone piece itself. Paver #P-0882 measures 8"x8"x2.5" in size. We round off the thickness to either 1 for 1.5" thick, or 2 for a 2.5" thick paver. And most measurements are approximate, or what are referred to as "nominal". A term used for close or an accepted assumption.

As an example, the #CS-6531 is a Castle Stone style paver that is 6" top to bottom, 5" across the top, 3" across the bottom, and 1.5" thick. The P-6531 paver has the same measurements, but is smooth, not chiselled like the Castle Stone. Whereas a #P-6522 paver measures 6" top to bottom, 5" across the top, 2" across the bottom, and is 2.5" thick. It is a smooth cobblestone style.
