Chapter 21 (1/2)
”Hoo...”
Jiangnan breathes out gently to calm down.
The original stone has been fixed on the metal frame, so it needs to be cut with a knife
The raw stone to be cut is the one with low value, and the success rate test price is about 50000.
Before cutting, Jiangnan was testing
”You can see green in one centimeter 0%……”
”You can see green in two centimeters 100%……”
”You can see green in 1.5 cm 100%……”
”You can see green in 1.3 cm 0%……”
”You can see green in 1.4 cm 100%……”
OK！
Jiangnan decided to cut the depth, directly in the small cutting machine above the depth card, 1.4 cm.
This way of cutting can be done by him.
If it's other cutters, they will cut by 1 mm and 1 mm if they want to open the window. If they don't cut 1 mm, take a look at it
If you see the green, you should close the knife, otherwise continue until you see the green
Of course, we can't see green in the end. That's waste rock.
”Zizi...”
Set the depth, and soon the Jiangnan will be cut.
He put away the knife, took a breath, blew off the stone foam, took a flashlight from the side, and lit it down along the edge of the knife
I saw the green emerald in it.
”Not bad.”
The corner of Jiangnan's mouth curved in an arc and put away the cut stone.
Then put the other piece into the metal slot.
Doing the same test
”Green in one centimeter 100%……”
”Green at 0.5cm 100%……”
”Eh?”
”0.2 cm green 100%……”
”Ah...”
”0.1 cm green 0%……”
