There are many edge details your countertop fabricator can install on your countertop. The presentation below is from The Marble Insitute of America. The profiles and names are intended to standardize the names but your fabricator may have different designations. The cost varies by difficulty and by the equipment available to your fabricator. Many will not offer all these options. The type of stone may also impact which edge may be used on your stone. For example, some granites have stones of varying hardness that make certain profiles difficult or impossible to install.
