A bevelled edge means that countertop has an angled or rounded or edge to it. Bevel edges bring a contemporary look and may not cost extra if the bevel is on the top only.
Bullnose is a variation where the top edge is rounded more dramatically, and a full bullnose converts the edge of the countertop to a perfect half-circle.
A very common edge is the eased edge, sometimes called a straight edge. It has a square, boxy appearance, and no embellishments are cut into the granite.
The ogee edge consists of a tiered and curved effect that in profile resembles the letter S.
