Black diamonds, also known as carbonado, are extremely rare, and are found naturally only in Brazil and Central Africa. The cosmic origin theory is based on their carbon isotopes and high hydrogen content.

The only thing that saved me was talking to a local miner who gave me a “heads up” that private individuals owned all the mineral rights in that section.

Let’s set up a thought experiment: Suppose you had some material that ran one ounce per ton gold, which is generally considered high grade to fantastic grade depending on the circumstances.

I have found gold more than 200 feet above the river. It was not unusual for nuggets of an ounce or more to be found in these deposits, but fine gold and flakes are much more common.
