Polished Black Cosmic Granite Slabs

Cosmic Black is one of the most classic of all the granite color options.

It comes with many variations and you’ll want to see the exact stone 

that you’re going to use in your project. There are often quartz pockets on this stone 

as well which adds to the natural elegance.

The ideal rooms for cosmic black granite are kitchens and bathrooms. 

Not only does this provide a darker, more subtle look than some other options, 

but you can also match appliances and fixtures to your granite color. 

Cosmic black granite provides a beautiful white swirl throughout the black, displaying a light touch within the dark.

Black Cosmic Granite-1

The textures and colors in cosmic black granite can vary since it is a natural stone. 

You may have light browns and yellows mixed in with the white and black on your particular stone. 

This provides a unique appearance that is only found in your home, since no two stones are the same. 

This personalized touch can be chosen with any color granite and not just cosmic black.

Black Cosmos Granite

Cosmic black granite can be found throughout many portions of Brazil. 

The large stones are unearthed and then sanded down to create blocks

that can be used as various surfaces throughout the home. 

The blocks may have to be cut to fit the desired shape, but diamond saws can do so easily. 

This choice of granite may be hard to use on larger surfaces since they usually are found in smaller blocks. 

However, the right installer can expertly seam the pieces together and you will never know the difference.

The installation and care of black cosmic granite is generally the same as others. 

One of the biggest differences, however, is the fact that darker granite can be sealed 

and joined with other countertops and surfaces without being noticed as much. 

The dark color blends in well with the others, and with the right installation, you will not notice seams. 

The granite surface will have to be sealed and finished to ensure it retains its high quality. 

Consider the instructions given to you during the time of installation to keep your 

cosmic black granite surface looking the best that it can.
