  What 10-Baggers (and 100-Baggers) Look Like 
Now that it appears clear the bottom is in for gold, it’s time to stop fretting about how low prices will drop and how long the correction will last—and start looking at how high they’ll go and when they’ll get there. When viewing the gold market from a historical perspective, one thing that’s clear is that the junior mining stocks tend to fluctuate between extreme boom and bust cycles. As a group, they’ll double in price, then crash by 75%... then double or triple or even quadruple again, onl

Hardness, color and clarity scales
The Mohs scale measures the hardness or durability of minerals and natural gemstones. Hardness refers to the gemstone’s ability to resist abrasion. In other words, it describes the stone’s capacity to resist scratches from other minerals. If you were to take a diamond (has the highest score) and try to scratch its surface with a ruby (the next highest score), you would be unsuccessful. However, if you were to take the diamond and scratch the surface of a ruby, it would cause a scratch in the ruby stone.

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.
