The 5 Largest Gold Nuggets that Still Exist
Throughout gold rush and gold mining history, the discovery of a large gold nugget is a phenomenon which always causes excitement throughout a mining community as well as capturing the wider public's imagination.

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.
