Black diamonds come from outer space 
Outer space may also be the birthplace of the mysterious black diamonds known as carbonados. From the Portuguese word for burned or carbonized, carbonados were first found in Brazil in the 1800s and have since turned up elsewhere, most notably in central Africa. Unlike the clear diamonds of engagement rings, which are single crystals, black diamond consists of aggregations of individual crystals, which lend the gem its dark color.

5 Record Breaking Gemstones Even Billionaires Can’t Buy
As Elizabeth Taylor once said: “I adore wearing gems, but not because they are mine. You can't possess radiance, you can only admire it.” It’s a good philosophy, because when it comes to the world’s biggest, rarest and most extraordinary gemstone discoveries, no one—not even billionaire President Donald Trump—could afford the possession. We’re not talking about the average diamond engagement ring that sets you back $4,000 and was probably grown in a lab. And we’re not talking about the $3,000 ru

“Blockchain” Stocks Collapsing by 40 to 90
It’s not a pretty sight. Short sellers are in Nirvana with these creatures that had surged by hundreds or even thousands of percent in days after they announced a switch to “blockchain” in their business model or added “Blockchain” to their name. Their shares are now crashing. I have written about a number of these outfits and their crazy share-price moves and their silly stock manipulation schemes on the way up. Now, not much later, here’s an update on how they’re doing on the way down. UBI Blo

The productivity myth
Every now and then, there’s a rash of commentary on national productivity. And for the British, productivity is all part of the Brexit angst, with the OECD, the Treasury, the Bank of England and Remainers all saying the average Brit’s poor productivity just goes to show how much they need the certain comfort of being in the EU. As Hilaire Belloc put it, we must hold on to nurse, for fear of something worse.Only this week, the OECD came out with a paper repeating its disproved nonsense about the

Fed's 'Imprudent, Misguided' Yellen Knocks Gold Bullion to 5-Week Low as Chinese Jewelry Demand Falls

Why I Use Precious Metals ETFs for Trading and Penny Stocks for Long-Term Holding
To the extent that the market represents the sum of all of the collective opinions of every investor everywhere, I must declare myself to be a card-carrying misanthrope, carrying with me a complete revulsion of the current state of the financial markets into battle each and every day and night that markets are open for "trading" (if that what you must call it). I further wonder whether or not my current approach to stock investing is much different from the way my father used to view a Jimi Hend
