Features

• According to Keidel.com, quartz grows in clusters. After mining and manufacturing, clusters become the slabs---in a variety of colors and patterns---used to make quartz countertops.
  
  

Benefits

• Quartz countertops don't require sealant or surface conditioner to prevent staining or premature deterioration. Quartz countertops are stain-resistant and---because they are nonporous---quite resistant to bacteria as well.
  
  

Considerations

• One serious drawback to quartz countertops is that they are much heavier than most other countertops, including those made of granite. Safely and properly installing a quartz countertop requires several people---it should be done by trained professionals, urges Keidel.com.
  
  

Comparisons

• Quartz countertops are more resistant to mold than most other types of countertops. They are also much stronger than most countertops, including granite, says galttech.com.
  
  

Cost

• The overall cost of quartz countertop installation depends on the size of the project. According to December 2009 estimates from galttech.com, installation typically costs between $50 and $90 per square foot, including the cost of materials.
