Dolomite

Dolomite is a sedimentary rock made mostly of the mineral dolomite. Dolomites can look similar to marbles as they generally have a similar appearance and mineral composition.  Marbles are predominantly consisting of calcium carbonate; whilst Dolomites consist of calcium magnesium carbonate. People in the industry often refer to Dolomite as a “hard marble”. The reason for this is that those stones classified as Dolomites are harder wearing than Marble. Dolomites are generally denser stones providing higher scratch resistance and are not as easily etched by acidic substances (e.g., lemon juice) when compared to a typical Marble. Dolomites would sit in between a Marble and Granite on the durability scale.  Dolomites tend to come in shades of white to grey/blue. White Fantasy (aka Super White) is a well-known dolomite which has been an extremely popular choice for countertops in recent times. It is important to keep in mind that whilst dolomites tend not to etch as quickly or deeply as a typical Marble does, they can still etch so we recommend that clients select a honed or satin finish, especially for kitchen benchtop applications, as the effects of etching are barely visible on a honed or stain finish Dolomite but can be more visible on a polished finish.
