Black Cherry granite

[DS]

We recently installed a black cherry granite countertops. The customer is getting scratches in the gray matrix portion. Does anyone know what the gray is, and is there a solution to avoid scratches, other than using coaster?

Softer stones can be scratched from foot traffic. Dirt, sand, and grit from your shoes are an abrasive to stone flooring. This is why it is recommended to use rugs or mats near entry ways and to dust mop frequently.
Sanded grouts are capable of scratching softer natural stones.
Dragging furniture across your floor may scratch it. Try to lift, not drag your furniture.
Softer stone countertop materials such as marble and soapstone may be scratched from toys, cutting on them, or tossing your keys across them.
