I thought this was very interesting. Diamonds of gem quality are largely limited to very old kimberlite volcanic pipes however, there is some possibility that diamonds formed in impact craters could have value industrially. The efficiency and lower cost of manufactured stones make the mining of this impact deposit unlikely.

The article give a feel for the tremendous violence of an impact. Even diamonds could not form from the carbon rich gneiss at the center of this crater. As a result, the diamond rich breccia is found in a circle with a 12 mile diameter from the point of impact.

” In 2010 the worldwide production of synthetic industrial diamond was about 4.38 billion carats valued between $1.65 billion and $2.50 billion. This is an average price of about 50 cents per carat or less.”

You would have to literally mine a ton of diamonds a day to make it worth it.

I believe they’ve known about this for many years. They’ve kept it quiet so as to not flood the market and drive the prices down. Supply & demand, don’tcha know!

"5 to 8 kilometers in diameter"

"15 to 20 kilometers per second"

"thousands of cubic kilometers"

"metric tons"

"100 kilometer-wide"

I was born in America, where the common people are educated to use standard English measurements. Despite the fact that the academic class has adopted the metric system in their work, the average man and woman in this country has not.

I understand that a base 10 system of measurement is superior to others, but I also think it's arrogant when writers and scientists insist on using it to communicate to the broad American public when most of us only have a vague grasp of it.

It's really not that hard to communicate to us in a language we understand.

Does this mean that there could be diamonds formed by the Chesapeake Meteor which hit around the same time also leaving a 60 mile crater?
