There might be a quadrillion tons of diamonds 100 miles below Earth’s surface.

But the farthest we’ve traveled is 7 miles down, so how could we know that?

The American Chemical Society (ACS) is a nonprofit organization chartered by the U.S. Congress.

ACS’ mission is to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and all its people.

The Society is a global leader in promoting excellence in science education and providing access to chemistry-related information and research through its multiple research solutions, peer-reviewed journals, scientific conferences, eBooks and weekly news periodical Chemical & Engineering News.

ACS journals are among the most cited, most trusted and most read within the scientific literature; however, ACS itself does not conduct chemical research.

As a leader in scientific information solutions, its CAS division partners with global innovators to accelerate breakthroughs by curating, connecting and analyzing the world’s scientific knowledge.

ACS’ main offices are in Washington, D.C., and Columbus, Ohio.
