The most elegant homes in the world often include a plethora of exotic natural stone surfaces. 
But where do these stones come from?  And what’s the process involved in actually getting them into
my house?  Read below for a geological overview as well as the methods used in sourcing stones for
your home.

   Brazil is the world’s leading granite producer but it can also be found in other countries like
Italy, Spain, China, and India.  Granite is categorized as an “igneous” rock, meaning that it is formed from
cooled lava that seeps through the earth’s crust.  The majority of Marble for your home is produced in
Italy, with other countries like Spain, India, China, and Africa all yielding it as well.  Marble is classified as
a “metamorphic” rock, which is the process that happens when limestone is subjected to extreme
pressure and temperature, commonly created in converging tectonic plates.  Most marble is found in
large deposits that can be hundreds of feet thick.

The process of mining for both granite and marble is a difficult and laborious one.  Once a
desirable patch of stone is discovered, quarry managers determine the best method of exacting the
stone -which can include techniques like drilling and even planned detonation.  Once a large block of
stone is extracted, it is divided into smaller chunks (which can weigh between 15,000-40,000 lbs each
depending on stone type).  These chunks are eventually cut with a diamond saw into the slabs that are
polished and sent to stone suppliers (like UGM!) for use in your home.

These stones have undergone millions of years of natural production to make it onto your
countertop.  We at UGM understand how special these natural stones are, and hope that you’ll turn to
us for all of your future needs!
