A really big stone

 

In case you missed it, the second-largest diamond ever found was found a couple of weeks ago in Botswana.  Bonus -- it's a blue-white diamond.

(Actually, though, I think it's the second-largest clear diamond. Because the "Sergio", a black diamond (a carbonado), appears to have been the actual largest -- at least according to this: List of largest rough diamonds)

All I can say is, somebody better start making a crown.

This one was just discovered, so I doubt that any plans have been made for it yet. My first question, which may be on the minds of many people, is:  do they go for the record?

The world's largest cut diamond is the Golden Jubilee, 545.67 carats. The second-largest, and more famous (and also blue-white, aka colorless) is the Cullinan I, in the scepter of the British Crown Jewels, 530.2 carats.

So given the size of this new one, will they consider trying to cut at least one chunk into a faceted diamond heavier than the Golden Jubilee?  Because opportunities like this don't come along very often.

Second-largest diamond ever, 2,492 carats, unearthed in Botswana

"Lamb [president and chief executive of Lucara Diamond, the Canadian mining company] credited X-ray technology that has been used by the company since 2017 for the detection of the massive diamond, which was retrieved intact."

There aren't too many pictures of it yet; there are a couple in the article, one of which is the same as shown below.
