The Marble Institute of America (MIA) has introduced the Home Approved Stone program, a national stone safety-testing program where all products that pass the uniform test will be labeled with a Home Approved Stone logo, which indicates they have been screened and approved for interior use.

The MIA says it has begun “distributing stringent testing protocols across the nation, which granite distributors and fabricators can use to test granite for the presence of radon and radiation.”

The organization further adds that the details of the program’s implementation are “still being finalized with scientific consultants and will be in place before any stone is labeled with the ‘Home Approved’ sticker.”
