That pricier granite does not necessarily mean it is a better quality?
The real factors that impact cost & quality:
Quartz, a type of engineered stone, has a more contemporary look and typically has a more solid color. This type of stone is good for almost everything, including kitchens, fireplaces and bathrooms.
Because of the various natural designs and colors within granite, it has much more character than other stones. This type of stone is good for almost everything, including kitchens, fireplaces and bathrooms.
Marble is a calcium-based product. It is softer than stone which makes it good for a master bath, fireplaces, or powder rooms that do not receive excess use. Because it can stain and etch, it is not recommended for kids bathrooms, or places where products like tooth paste will cause etching.
