World's Biggest Pink Diamond Mine Closes

he world's largest pink diamond mine has shut its doors after exhausting its reserves of the expensive gems, global mining giant Rio Tinto said Tuesday.

The Argyle mine, in the remote Kimberley region of Western Australia, churned out more than 90 percent of the world's pink diamonds -- sought after for their incredible rarity.

The seam was discovered in 1979 and the Anglo-Australian firm began mining operations there four years later.

It has since produced more than 865 million carats of rough diamonds, including a small but steady stream of prized pink stones, according to Rio Tinto.

Argyle employees and indigenous landowners attended a ceremony at the shuttered mine to mark the end of operations.

The company expects efforts to decommission and dismantle the 37-year-old site will take around five years.

"A new chapter will now begin as we start the process of respectfully closing the Argyle mine and rehabilitating the land, to be handed back to its traditional custodians," mine manager Andrew Wilson said.

Over the past two decades, the value of pink diamonds has risen by 500 percent, Rio Tinto's Sinead Kaufman told public broadcaster ABC.

The end of operations at Argyle is likely to push the price of the diamonds even higher, jewelers say. At current rates, the gems can fetch up to $3 million per carat.

Diamonds are typically clear, but jewels such as those mined at Argyle become pink through extreme heat and pressure during their creation. Those conditions warp their crystal lattices and alter the reflection of light as it passes through the body of the diamond.

Millions of Southern Californians were on edge as a final round of dangerous fire weather was forecast for the region on Wednesday, along with a rare warning of a “Particularly Dangerous Situation” for an area near where two massive blazes have killed at least 25 and destroyed thousands of homes.

Firefighters got a reprieve Tuesday when winds were unexpectedly light and they were able to make progress battling the two huge Los Angeles area fires and quickly snuff out several new fires.

The Eaton Fire burning just north of Los Angeles and the Palisades Fire that destroyed much of the seaside LA neighborhood of Pacific Palisades broke out Jan. 7 in conditions similar to what’s expected Wednesday. High winds last week pushed flames at remarkable speed and carried fire-sparking embers sometimes miles away.

The National Weather Service issued red flag warnings – done when temperatures are warm, humidity is low and strong winds are expected – from 3 a.m. to 3 p.m. from the Central Coast 275 miles (443 kilometers) south to the border with Mexico. The “Particularly Dangerous Situation” was in effect for an area that includes parts of Los Angeles and Ventura counties.

“Key message: We are not out of the woods yet,” the weather service said in a post late Tuesday. “The winds underperformed today, but one more enhancement could happen tonight-tomorrow.”

More than 77,000 households were without electricity as utilities shut off power to prevent their lines from sparking new blazes.

A state of alert

Weary and anxious residents were told to be ready to flee at a moment’s notice. They remained vigilant, keeping an eye on the skies and on each other: Police announced roughly 50 arrests, for looting, flying drones in fire zones, violating curfew and other crimes.

Of those, three people were arrested on suspicion of arson after being seen setting small fires that were immediately extinguished, LA Police Chief Jim McDonnell said. One was using a barbecue lighter, another ignited brush and a third tried to light a trash can, he said. All were far outside the disaster zones. Authorities have not determined a cause for any of the major fires.

Among nine people charged with looting was a group that stole an Emmy award from an evacuated house, Los Angeles County District Attorney Nathan Hochman said.

The biggest worry remained the threat from intense winds. Now backed by firefighters from other states, Canada and Mexico, crews were deployed to attack flareups or new blazes. The firefighting force was much bigger than a week ago, when the first wave of fires began destroying thousands of homes in what could become the nation's costliest fire disaster.

Kaylin Johnson and her family planned to spend the night at their home, one of the few left standing in Altadena, near Pasadena. They intended to keep watch to ward off looting and to hose down the house and her neighbors’ properties to prevent flareups.

Preparing for another outbreak

Planes doused homes and hillsides with bright pink fire-retardant chemicals, while crews and fire engines deployed to particularly vulnerable spots with dry brush.

Los Angeles Mayor Karen Bass and other officials who were criticized over their initial response expressed confidence that the region is ready to face the new threat. The mayor said she was able to fly over the disaster areas, which she described as resembling the aftermath of a “dry hurricane.”

Winds this time were not expected to reach the same fierce speeds seen last week but they could ground firefighting aircraft, LA County Fire Chief Anthony Marrone said.

He urged homeless people to avoid starting fires for warmth and to seek shelter.

Wildfires on the rise across LA

With almost no rain in more than eight months, the brush-filled region has had more than a dozen wildfires this year, mostly in the greater Los Angeles area.

Firefighters have jumped on small blazes that popped up, quickly smothering several in Los Angeles county, including a blaze Tuesday evening in the Angeles National Forest.

The four largest fires around the nation’s second-biggest city have scorched more than 63 square miles (163 square kilometers), roughly three times the size of Manhattan. Of these, the Eaton Fire near Pasadena was roughly one-third contained, while the largest blaze, in Pacific Palisades on the coast, was far less contained.

The death toll is likely to rise, according to Los Angeles County Sheriff Robert Luna. Nearly 30 people were still missing, he said Tuesday. Some people reported as missing earlier have been found.

Just under 90,000 people in the county remained under evacuation orders, half the number from last week.

Hollywood on hold Hollywood’s awards season has been put on hiatus because of the crisis. The Oscar nominations have been delayed twice, and some organizations postponed their awards shows and announcements without rescheduling.
