Above is the range panel located at our factory on Portland which shows the typical geological characteristics of Grove Whitbed™
Shelly Whitbed - predominantly grey shells with some large white shell fragments. The shells are mainly large thin clams up to 100mm long laid parallel to the bedding.
The shells are randomly distributed across the stone, but due to the large clam shells, some banding is evident particularly in larger slabs.
The large clam shells are associated with voids. The texture in between the voids is often tight and dense.
Typical Portland colour - creamy/white, although the large concentrations of grey shells can darken the overall colour.
