HI ALL!

Here's some more info about this rough- and diamond cutting in general......

I can't emphasize the importance of waste- or lack of it in planning the diamond.

Think about this- we go thru a lot of effort to mine this thing, then simply grind away a part of it?
You definitely want the portion you grind ( cut) off to be the smallest possible.

Like Polished diamonds, Rough diamonds are sorted into different categories.
Of course size is the first factor taken into account. The large  pieces are quite rare.

Another characteristic by which rough stones are sorted has to do with how they'll be cut.
In many cases the rough is octagonal, like this one


The diamond in the youtube above was be sewn ( sawed)  into two pieces, which will then each became their own diamond.....

Here's a diagram of an octagon which explains what I'm talking about:


Below I've marked where they might  cut the diamond, with a very special saw- can you see how sawing off the top part gives you a piece which already has the profile of a diamond-


A lot of the light yellows we get are actually top pieces after polishing.

Anyway, such rough diamonds are known as "Saw-ables"

The subject of our contest is known as a "Make-able"

With "Make-able" rough, you put it right on the cutting wheel.
It makes the most sense to polish it into one diamond. AS the 5.28carat one will be.

AS the diamond is cut., and we have a better idea of when the diamond ( and contest) will be finished, we will give you guys ample notice. We'll also let you know when we give the last clue.
For us running the contest, it makes it more fun too- and it allows us to add to the knowledge base as we go along.



Hi Guys,
Of course it's  contest- and anyone is free to frame their entries as they wish...but if it were me.....
I'd wait till right near the very end for my second guess- this way you could use any and all the clues.

I'm going to guess 1.19 as my first guess and go a little higher with a 2.09

As far as shapes I'm thinking cushion or pear.

Hi Everyone- we anticipate the cutting to take about one month.

As diamonds are the hardest natural substance cutting ( polishing) can take quite a long time.
Sometimes a facet is easy- other times a single facet can take up a few days of the cutter's attention. When I say " a few days of his attention"- it might take that long to smooth that particular facet- but during this time, the cutter might have 2 ( or more) other stones on the wheel ( sometimes two diamonds can polished on the same wheel)

My first guess:

Final Weight: 3.97ct
Cut:  Pear Shape
Color:  FLY

Guess One:

2.73 Carats
Cushion Cut
X-Y Color
