Related: About this forumNice Chunk of Carbon
The second-largest gem quality diamond ever discovered has been unveiled by a Canadian diamond mining company this week.
Announced by the Lucara Corporation, the 1,111-carat diamond was unearthed in the company's Karowe Mine in southern African nation of Botswana.
William Lamb, the CEO of the mining company wrote in a press release, ""The significance of the recovery of a gem quality stone larger than 1,000 carats, the largest for more than a century and the continued recovery of high quality stones from the south lobe, cannot be overstated."
The only diamond larger than this example was the Cullinan Diamond, which when uncut weighed in at over 3,000 carats, was eventually cut into pieces and placed in England's Crown Jewels.

There are five carats to the gram. There are 28 grams in an ounce. There are 454 grams in a pound.
That's 222.2 grams, which is .489 pound.
Wow! Biggest diamond since the Cullinan. Note: Diamonds (cubic carbon) are face centered cubic structure.
Most crystals look like 2 pyramids stuck together base-to-base.

Over the next few millions of years this pristine diamond will turn into graphite.
Just as I planned all along...
MUHAHAHAHA!

(62,534 posts)4. just keep believing the propaganda that diamonds are "rare" and therefore...
justify their expensive price tags.
this little beauty will generate, (if they cut it all the way down) hundreds of diamonds.
