Newly Found 'Star Sapphire' Is Worth $100M

(NEWSER) – Kate Middleton's $45,000 sapphire ring can't compare to this showstopper: Gemologists in Sri Lanka say they've dug up the largest blue star sapphire ever found at a mine in Ratnapura, known as the City of Gems. The star sapphire—named for the star-shaped reflection that appears on its polished surface—weighs 1404.49 carats, according to a certificate from the Gemology Institute of Colombo; the previous record-holder weighs only slightly less at 1,395 carats, reports the BBC. "When the stone was brought to me I suspected that it might be the world's largest blue star sapphire, so I took a risk and bought it," the anonymous owner says. He won't say what he paid for the stone, reportedly found last August, but experts say it's worth about $100 million.

The owner thinks he could get as much as $175 million for it at auction, but "I am not interested in selling it at the moment as it first needs international exposure," he tells Ceylon Today. He adds the rock is too big to be "set in any kind of jewelry" and is "destined to be a priceless museum piece." He is said to have called the gem the Star of Adam, based on the Muslim belief that Adam traveled to Sri Lanka after he was banished from the Garden of Eden and cried tears that became the region's gems. Sri Lanka's gem industry is on the rise: An official tells CNN exports have increased by 135% in recent years, due in part to interest in Middleton's ring.

Second-Largest Diamond in History Is Found

(NEWSER) – Canadian mining outfit Lucara Diamond has just uncovered the world's second-largest diamond—and the biggest one found in more than a century. Found in the south lobe of the Karowe mine in central Botswana, the Type IIa stone is 1,111 carats and just slightly smaller than a tennis ball, reports Bloomberg. Only the 3,106-carat Cullinan Diamond among the British Crown Jewels, found in South Africa in 1905, is bigger; the largest diamond found in the last 100 years was a 603-carat stone. However, that find has now been shuffled to third place, thanks to a second diamond newly found in Karowe that's 813 carats, reports the BBC. A 374-carat stone was also found.

"I am truly at a loss for words," Lucara's CEO says. "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." So what is this rare rock worth? "It is almost impossible to estimate a value for such an extraordinary stone given that a valuation is highly dependent on the color, clarity, and cutting and polishing characteristics," an analyst says. Bloomberg notes that Lucara sold a 341.9-carat stone in July for $20.6 million. Others tell the Financial Times that the find is "a balance sheet changing development" for Lucara, which recently made large diamonds its focus. (This blue diamond, a daughter's birthday gift, just sold for a record amount at auction.)

Mining company claims to have found second largest diamond in history


The boss of a small diamond company says he is at a "loss for words" after several large diamonds, including the largest in more than a century, were recovered in Botswana.

Canada-based Lucara Diamond said the 1,111-carat stone was found on the south lobe of its Karowe mine in the southern African nation, declaring it the world's second-biggest gem-quality diamond ever recovered after the Cullinan diamond which features in the Crown Jewels.

The company said that it was yet to be fully examined and processed, meaning it was impossible to put any kind of value on it.

It will be determined by its color and clarity and how it is cut.

After Lucara announced the gem's discovery, it confirmed 24-hours later that two further stones - the largest being an estimated 813 carats - had been found as well at the same mine.

The focus, however, was on the Type IIa diamond - which measured 65 mm by 56 mm by 40 mm.

Hey I watched this video tonight from probably the largest bike related content provider on YT whilst they tour a producer of Graphene.

I'm only posting it here as they say (in a very layman way) that graphene and diamond are actually quite similar once you arrange a few molecules around.

The Star Sapphire is Awesome ! I would be curious as to how many Hi- Market diamonds they get out of the diamond.

It would be really exciting to be the "Finder" of these things!  ::)

Wonderful! I saw a pink star sapphire once, which I wanted badly, but the cost was prohibitive at the time.

In hindsight, I wish I'd gone into hock for it.
