Re: [Geology2] NC Farm Produces Emerald Shaped Into Massive Gem

Hi again,

Here ya go: http://en.wikipedia.org/wiki/North_American_craton

If you have questions after reading the section on "Interior Platform," just ask.  The best parts of geology, for me, are historical geology and vulcanism. "Old" is "in." :)

I could definitely check the Roadside Geology book but wouldn't know what to look f for interms of the oldest sections of the NA plate. Would I be looking for basalt rock or granite or what? Guess the book can tell me  but hey.. I like talking online..lol.

You'd have to check online or in a book of the likes of "Roadside Geology" in order to find the exact location.

We have a group here that pans for gold.. they usually show up at the WI geological society gem and mineral show put on here at Hart Park in early May... they say sometimes they find gold in our rivers up here although admittedly it is more of a social group. I dont' think there will be a gold rush any time soon..lol.

DALESIO, Associated Press Writer Emery P. Dalesio, Associated Press Writer – Mon Aug 30, 7:07 pm ET RALEIGH, N.C. – An emerald so large it's being compared with the crown jewels of Russian empress Catherine the Great was pulled from a pit near corn rows at a North Carolina farm. The nearly 65-carat emerald its finders are marketing by the name Carolina Emperor was pulled from a farm once so well known among treasure hunters that the owners charged $3 a day to shovel for small samples of the green stones. After the gem was cut and re-cut, the finished product was about one-fifth the weight of the original find, making it slightly larger than a U.S. quarter and about as heavy as a AA battery. The emerald compares in size and quality to one surrounded by diamonds in a brooch once owned by Catherine the Great, who was empress in the 18th century, that Christie's auction house in New York sold in April for $1.65 million, said C.R. "Cap" Beesley, a New York gemologist who examined the stone. While big, uncut crystals and even notable gem-quality emeralds have come from the community 50 miles northwest of Charlotte called Hiddenite, there has never been one so big it's worthy of an imperial treasury, Beesley said.
