HEADSTONE WITH KERB SET
The headstone (which can have any top shape - showing here is an 'arc' top shape) and kerbs are set onto a concrete frame foundation and can have either stone chippings within the bed or soil. Vase posts can be incorporated within the kerbs.
HEADSTONE WITH KERB SET AND FULL COVER SLAB
The headstone (which can have any top shape - showing here is an 'arc' top shape) and kerbs are set onto a concrete frame foundation and topped with a full cover slab.
GRAVE VASES - FLOWER VASE
A cube of stone with a metal-spun insert (which is called the 'flower container' and domed lid with holes for the flower stems. They are available in different shapes and sizes, but this is the most basic type.
TABLET
Usually square, but can be rectangular and has a flat face - which lays on the ground - it can be made of any stone type and can be any size - but they are usually quite small - say 12" square - up to about 15" or 18" square.
WEDGE MEMORIAL
Similar to a tablet, but with a sloping face - it is higher at the back than at the front which allows rain to run off the surface more readily than a tablet.
DESK MEMORIAL
As the name suggests, a desk memorial is similar to an old school desk - with a sloping face and flat top area - which can incorporate a flower container if so desired.
OPEN BOOK LAWN TYPE
A popular choice if the memorial is destined for two inscriptions.
