"A rare diamond known as the Pink Star has been sold in Hong Kong for more than $71m (£57m), setting a new world record for any gemstone at auction. The oval-shaped 59.6 carat stone was bought after just five minutes' bidding at Sotheby's, reports said. It is the largest polished diamond in its class to go under the hammer. It sold for $83m in Geneva in 2013 but the buyer later defaulted. The record until now was held by the Oppenheimer Blue, which sold for $50m last May."

Can you recommend any places that would be good in Alaska. I think copper is much prettier than any other metal, having a few nuggets to put in the display would be neat!
Years ago I found a small copper nugget about the size of a 22 bullet at Matanuska glacier, sure liked that little nugget. Ended up putting it in a small vial of gold,
Sometime later I sold a spiral panner to a lady with a handicapped son. He really liked prospecting and she thought it was really helping him with his disability. She told me they were not having good luck finding gold and didn't know the difference between gold and fools gold. Well I marched rite into the house grabbed a vile of gold and gave it to her!
She really appreciated that and I felt good about myself until I realized that 1/4 oz of gold also had that little copper nugget in it. Still irritated about that!
Many years ago I bought this 105 grammer on ebay and it came out of the United States. I don`t know if this nugget is natural or tumbled and the glossy side has never dulled so I guess its got some kind of varnish on it. I`ve also got a 16 ouncer somewhere in the house that is all jagged and rough with green bits all over it.
Does anybody detect for copper in the States, does copper only come out of mines, or can copper just be lying around on the ground? cheers Dave
I found this rock while gold dredging last year in Indiana in a gravel bar. I didn't realize until a month ago,it is a crystal of sorts ,white and dark blue and a black splotch ? It is a double crystal,Indian head penny for size comparison against a chunk of coal I found in another creek. Have been told it might be a Blue Sapphire crystal or Blue Beryl Crystal? Maybe Chris Ralph will know the answer?
Dunno how it got into an Indiana gravel bar tho? Brought down by the glaciers with the gold from Lake Superior area perhaps? There was a pile of fine gold in the gravels on an inside bend of this 15 foot wide creek and numerous pretty rocks. I busted one open today and it is a Pink/white quartz inside. I guess it pays to eyeball a bit when gold hunting...I wonder if my crystal could be made into a ring or something?
Just measured a bit. The top layer is approx. 3/4 inch across the parallel flats and 5/8 inch thick. If its a sapphire, how many carats might it weigh? Should I take it to a jeweler?
Sunday, and i should go hunt for something...
there are rocks out there not in the fields in the USA, but they can be found in shops and rummage sales as items carried home by travelers from exotic lands. the stone I'm referring to is a very special white jade found in a specific area in China. the jade is hetian nephrite and comes from an area in Xin Jiang, China very near Turkey. it is easily confused with other white nephrites and tons of other white jades are passed off as hetian, the differences in the materials are slight, but the difference in value is tremendous.
the most valuable of the hetian jades and most highly prized by collectors are fatty pure white specimens found in river beds with the outer matrix worn off by the action of the water and surrounding gravels. the very highest quality hetian nephrite will fetch in the neighborhood of $1000.00 per gram US dollars. This jade has been prized for centuries and spurred a movement of sorts not unlike California's gold rush, the entire area is now off limits and under state protection from the ravages of collectors.
The gold nugget is 9.5 grams and the little jade fish is 5.2 grams, the nugget is worth in the $400. range depending on the buyer this little fish from the studio of Xio Fan in Suzho, China would bring close to $10,000.00 (or a new GPZ) from a knowledgeable buyer. in the second picture is another hetian pebble of aprox 30 grams a slightly lesser quality, but showing very good skin, alongside the little fish for comparison. the slight differences in color and clarity drop the value by as much as 1/2 of the top quality per gram.
so if you are out hunting in in odd shops and come across a curious little white rock some traveler carried home from vacation???
