QUESTIONSelecting Onyx - I am an architectural designer who currently has a client who is looking for an onyx slab (color: honey/pale orange/pink/some white). The slab must be able to accommodate a finished 9' x 2' rectangle. Your prompt attention would be appreciated.
ANSWERANSWER - Color and look is very subjective. Then you need to consider performance based on physical properties. Unlike other materials that you specify for a project, stone is natural so you have to select it for the project and application to ensure it is suitable.
The best way to find what you want is to visit a stone importer who has a large selection of onyx. Go through the inventory and pick the slab that is of the right size and looks. Then substantiate with the supplier that it has the right physical properties to perform for its intended use. Good Luck!
