    Default Strange diamond find

    Strange rock containing 30,000 diamonds baffles scientists

    Miners unearth rare rock stuffed full of diamonds that has baffled scientists



    By Andrew Trotman 5:20PM GMT 17 Dec 2014




    When Russian miners pulled a strange red and green stone out of the ground, they immediately knew it was different to the thousands of tons of ore they process every day.

    In fact, what workers at Alrosa's Udachnaya diamond mine had unearthed was a 30mm rock that contained 30,000 diamonds - a conentration 1m times higher than normal.

    However, despite the rare find the company donated the rock to the Russian Academy of Sciences, as the diamonds are so small that they cannot be used as gems.

    After scanning the rock with X-rays, scientists found that the diamonds inside measure just 1mm and are octahedral in shape - similar to two pyramids stuck together at the base. The red and green colouring comes from larger crystals of garnet, olivine and pyroxene.

    "The exciting thing for me is there are 30,000 itty-bitty, perfect octahedrons, and not one big diamond," said Larry Taylor, a geologist at the University of Tennessee, who presented the findings at the American Geophysical Union's annual meeting. "It's like they formed instantaneously. This rock is a strange one indeed."

    Scientists are excited at the finding as they hope it will shed further light on how diamonds are made. They know diamonds are crystals of pure carbon that form under crushing pressures and intense heat, mostly formed in the Earth's mantle, the layer beneath the crust or surface layer, at a depth of about 150km. However, certain processes in their creation remain a mystery.

    "The [chemical] reactions in which diamonds occur still remain an enigma," Mr Taylor told Live Science, which first reported the story. \

    Mr Taylor works with researchers at the Russian Academy of Sciences to study Udachnaya diamonds.

    Russia is the largest diamond-producing country in the world, and produced more than 33m carats last year. State-controlled Alrosa is the world's leading diamond miner, accounting for 99pc of Russia’s output and 27pc of global production. Its sees rough diamond revenues of more than $4bn a year.

    That is pretty cool. Someone must have pretty good eyesight to spot a rock that small. 30mm is less than an 1-1/4" inch in size. Pretty neat just the same and would like to have it in my collection.

    Me too. I love different looking rocks and minerals.

    I brought this back for a trip to Brazil back in the day.

    Cool Red, how large is that piece?

    I have a few geodes, lots of slabs and a nice pyrite sample in matrix from Spain. Small collection. Had lots of natural glass agates until the kids got ahold of them..lol

    Back in 1973 I did some timber cruising under contract. We had to go to this mountain side on one job. Well turns out this area was the silver capital back in the late 1800's and early 1900's. Lots of mines and Galena samples were everywhere. I regret not bagging a few samples now.

    Very nice samples Red.
    Digbird, I always bring back a rock samples from my travels.

    A few years ago we went to Niagara Falls NY and went to the bottom of the falls. I grabbed a brick size rock from the bottom and carried it all day in a backpack. When the wife found it I was in trouble. I also grabbed a Granite Paving block from the US Capital Grounds, they were repaving a section and had a pile of extras. I figured with all the taxes I pay, I own it right.

    That's a great display piece Red.

    I was young Boss and a was winter when we worked there. Snowshoes and snowmobiles were the mode of transportation. Adits or mines everywhere and thought one day I would return to explore without the snow but never did. But you're right I should have taken a couple of samples as they were everywhere in those days. Exploring the old mines was the fun part of that job. Silver wasn't worth too much back then in 1973.

    Probably the cheapest way to get some nice samples Yellowsnow. I would have to drive 700 miles, pay motel room and meals and a 1 day hike up into the mountains. A 1oz. coin trade for a display sample is cheap.
