What we do here, actually, is the QC of the diamonds.
And because every stone, after it's processed,
we have to do the QC.
And because diamond polishing is a [INAUDIBLE] procedure.
So every process, they need to take special care.
When you do a mistake and [INAUDIBLE] all the way back.
So before going to our next process,
they have to do the QC.
And if there's any mistake, like if there
is some rough on the surface, or the [INAUDIBLE] not good,
then they have to do it first before they
go to the next process.
Actually, the colors of the parcel
means the factory number of the stone.
Like if these were just the DTC okay,
then it may be in blue color.
And if that one is from Alrosa that one
will be in a purple color.
It makes the workers and all the people
more easy to recognize now-- the parcel.
So it is the kind of visual management--
make use of the color.
He's checking a big stone here.
So now he's checking the pavilion of a big stone.
So he has to check facet by facet, including
how the workers do their [INAUDIBLE].
If there's any polish line on the facet, and then
the symmetry to see whether its facets are
equal to another the size of it.
So here is some stone in different stages.
So first of all, okay, this is the label of the [INAUDIBLE].
Okay, so it is rough we always originally have.
So first of all, we have to saw the stone.
And after sawing we have to do the bruting.
So after bruting, we have these stone like this.
So we only have the outlines of the stone with round shapes,
but there's nothing on the diamond.
There's no facet on it.
So afterwards we have to do the bruting of the diamond.
So the bruting normally, we will do
the eight facet on the pavilion, and then eight
facet on the crown.
So it look more like a diamond now.
So after the bruting stage, we will do the pavilion.
So after finishing the pavilion, the stones look like this.
And this one is another example, this one,
we don't have eight facet on the crown.
So the stone will look like this.
We will add the rest of the facet on the crown,
so the stone will become shiny.
It's a shiny diamond.
So this one is a shiny diamond, if all the
facet on the pavilion.
And this one actually is close to finish.
It's not really done because it still have eight facet,
the star facets has not been polished.
So after the eight facet of the star facet polished
[INAUDIBLE], and the diamond will be finished.
