Aside from oil and lean hogs, 2019 has been a tough year for commodities. Coffee prices have fallen 9%, natural gas is 11% lower and soybean prices have fallen 7% to name just a few. The diamond industry is also in a slump, Bloomberg reports.

What's new: De Beers revealed Tuesday its diamond sales fell to a 2-year low, underlining a slump in the industry worldwide. Sales fell 25% from a year ago and were down 29% from an offering last month.

What's happening: "Diamond miners are struggling across the board, especially those producing cheaper and smaller gems where there is too much supply," writes Bloomberg's Thomas Biesheuvel.

  • Diamond miners also have been hit by a shortage of financing for buyers and stagnant end demand.
  • The Indian rupee's weakness against the dollar has made gems more expensive for Indian manufacturers, who cut or polish about 90% of the world’s stones.

The Supreme Court ruled early Tuesday that federal executions can resume, reversing a lower court decision and paving the way for the first lethal injection since 2003 to take place at a federal prison in Indiana, AP reports.

The big picture: A lower court had delayed the execution, saying inmates had provided evidence the government's plan to carry out executions using lethal injections "poses an unconstitutionally significant risk of serious pain."

More Republicans say they're wearing masks

Data: Axios/Ipsos poll; Chart: Andrew Witherspoon/Axios

Nearly two-thirds of Americans — and a noticeably increasing number of Republicans — say they’re wearing a face mask whenever they leave the house, according to the latest installment of the Axios-Ipsos Coronavirus Index.

Why it matters: A weakening partisan divide over masks, and a broad-based increase in the number of people wearing them, would be a welcome development as most of the country tries to beat back a rapidly growing outbreak.

Buildings are getting tested for coronavirus, too

Testing buildings — not just people — could be an important way to stop the spread of the coronavirus.

Why it matters: People won't feel safe returning to schools, offices, bars and restaurants unless they can be assured they won't be infected by coronavirus particles lingering in the air — or being pumped through the buildings' air ducts. One day, even office furniture lined with plants could be used to clean air in cubicles.
