Hello Friends
[3]
Welcome back to Du-Gemology's diamond education program,
[6]
Friends, this video is about diamond cutting and polishing
[9]
How are the diamond cutting and polishing done?
[12]
You want to know whether a diamond is cut with a laser or is rubbed by hand.
[17]
What is the process of manufacturing diamonds?
[20]
So let's start this video and we understand how diamond cutting happens
[25]
See, there are mainly three types of steps for cutting polishing of diamond, (1) the first step is called - Rough diamond Assortments
[34]
(2) the second step is called – Planning and Marking
[37]
and, (3) the third step is called – Cutting and Polishing or Shaping and Polishing
[42]
so, I won't make this video too long
[44]
very short and very quickly let me explain to you
[47]
What Happens in the Manufacturing Process of Diamond
[49]
Yes, however, I will make details videos on different topics
[55]
First of all, there is Rough Diamond Assortment
[57]
What happens in Rough Diamond Assortment Rough
[61]
Diamond is sorted, Rough Diamond is sorted
[64]
shape-wise, size-wise how much weight will be recovered that wise
[68]
and the most important saw able or Makeable wise
[73]
Now, what is saw able and makeable?
[75]
Meaning of the word 'makeable'
[76]
That such a diamond, which will be made straight, means straight Bruiting, Shaping will be done and Cutting Polishing will be done.
[83]
and saw able means to cut it into two pieces, three pieces, or four pieces
[88]
Makeable means that a single diamond will be produced from a rough
[92]
But, saw able means that multiple pieces will be removed from a rough. one big piece will come out
[97]
the small pieces that are left in the side,
[99]
More Pieces Will Be Removed From Them Too
[101]
So, in Rough Diamond Assortment it is decided that
[105]
Diamond is makeable or saw able
[108]
if the diamond is saw able
[109]
So that diamond is sent to the laser department, it is sent to the laser cutting department.
[113]
In the laser cutting department, that diamond is cut into two pieces with the help of a laser.
[118]
how will it be cut
[120]
Therefore, the one who is planner.
[122]
What does he do when he hits the sign on the diamond?
[124]
This is called marking or simply saying marking.
[128]
With a marker pen, they mark that it has to be cut into two pieces.
[132]
So, where does the sign come from?
[135]
At the same time, by aligning them exactly, the one who is going to laser cutting cuts it with laser.
[140]
So there is a small clip, you can see
[142]
How is laser cutting done?
[193]
well
[194]
In this you saw, how the laser is being cut, how it was first aligned, then how, the diamond was cut by laser cutting.
[203]
good
[204]
Now if diamond is makeable
[206]
Suppose it was saw able
[207]
If there is a makeable diamond, then what is a makeable diamond?
[210]
Goes to planning and makeable department
[212]
Panning and marking means to plan the diamond
[215]
and planning and then marking
[217]
Now Planning and Marking are of two ways
[219]
One is Manual Planning
[221]
Manual planning means that the person himself plans, looks through the eye loop and then plans from where it should be cut.
[227]
From where it should be made, its table, which side should be placed, how to make its culet and in addition to manual, serine planning
[235]
The word Serin actually means a company that makes machines, which makes software.
[241]
And, as soon as it scans, the diamond is scanned and comes to the computer on its three-dimensional view system.
[247]
and
[248]
Then it is seen how to get its maximum output.
[251]
There is only one purpose of planning, pay attention
[253]
There is only one purpose of planning and that is
[256]
money,
[257]
Every piece of rough is priceless,
[260]
The maximum output from that rough diamond has to be extracted from the piece of that rough.
[264]
They have to extract more and more output, they have to extract more and more value.
[269]
It is not necessary that in every factory or in any one factory, only excellent cut diamonds will be extracted, it is not necessary.
[276]
It is to be seen that if a very good cut can carry more weight, or a good cut can bring more weight, earn more, then will cut in a good cut.
[283]
It is not necessary that it should be cut in good clarity in VVS or VS only.
[286]
If we don't see that we cut it in SI 2, cut it in I 1, and recover more weight, if we get more price in the market, then we will cut it in that way
[293]
So every once in a while, the rough planning
[296]
That is, price wise, how do we get maximum output- maximum value
[302]
So now we do this, we go to serine planning
[305]
How is serine planning done? So let's see how Serina is done in planning.
[309]
A complete scanning was done by the machines, after how they were placed before.
[315]
scanning got a three-dimensional view
[317]
After that it is seen in different ways, different options are seen in which way it should be cut.
[321]
how to make it, from where to make it
[324]
From which side should the girdle be placed so that the maximum output maximum value is obtained?
[328]
When planning is done with serin, what do serin do after planning,
[333]
two things are done
[333]
first
[335]
There is a laser marker inside the machine itself, so as soon as the operator selects that I want to make it from here, they have selected the plan.
[342]
what does the machine do, it
[344]
marks with the laser, has to make a Girdle from here, to make a table from here, such a pavilion will be made. , makes a mark,
[350]
So when we take out the diamond, we see this mark, as you see it, here you are
[356]
well
[356]
after that, the plan that came out, a label of that plan comes out,
[360]
A sticker comes out, that sticker is placed in the bag or on the top of the packet.
[365]
So that the pudding where the department will pass through
[367]
Every department should know that in this diamond
[370]
What will be the angle, what will be the crown angle, what is the pavilion angle, how much table, what is the plan given by the machine, so that the craftsman should also know that we have to cut from the same plan.
[378]
The machine has given the plan, now it is the turn of the craftsman, he has to cut it in the same plan.
[383]
so
[384]
Till now we were looking at Planning and Marking, first we saw Rough diamond assortment, then we saw Planning and Marking,
[389]
After Planning and Marking
[391]
Now this, a diamond with a sticker, it will go to the next department, which is named Shaping, Bruiting, and Cutting Polishing
[399]
I am adding different words like shaping, bruting, cutting, polishing.
[402]
Simple to understand, that shaping diamond and polishing its cutting, grinding it, making facets
[409]
is ok
[409]
Facets means Pal
[411]
So, there used to be a time when I taught that in IDI in 2005 -2006, we did bruiting, the word bruiting means to give shape, to make a girdle, to give shape like a top.
[423]
At this time I am talking only about Round Brilliant Cut, I am not talking about any other word Fency.
[427]
So, when we used to come like a top, at that time we had to spin a motor by putting it on the motor.
[432]
There used to be a stick of two feet, we used to put it next to us and then used to wear it like this.
[435]
Used to collide diamond with diamond, today technology has increased, it has come a long way, today bruting is done by laser.
[441]
This is called 4 P Machine ( 4 P, 2 P )
[444]
ummm....
[445]
Hand Bruting is a very different process
[447]
Maxi Bruting is also used sometimes.
[449]
So, the latest thing that runs in today's time is the 4 P Machine.
[453]
so first I will show you the method of the 4 P machine.
[456]
So that this rough diamond is shaped, shaped like a top, the diamond is in the shape of a top.
[465]
Check it out, it's Clipping
[525]
Girdle's work in progress here
[551]
You see, how, its Girdle was made by laser, then the Table was cut, then the Crown was made, the Pavilion was made.
[559]
4 P, there are four processes in this, so in today's time is the latest - (4 P )
[564]
Factories that can't afford 4 P, it is the old way for them - 2 P
[568]
Look at the method of that 2 P, the method of 2 P is in such a way that how its girdleling is done, how its crown is made, how its pavilion is cut.
[578]
In this, the diamond is not made from a laser, but from another material, which is made from rubbish. Take a look at this process as well.
[587]
What do you see in this, that's Girdle.
[590]
This girdle is getting worn out.
[592]
You are seeing how the Girdle is being rounded, this is a 2P process.
[598]
It takes a little more time, where if 24 hours of work is done in a day in the 4 P process, the machine should be run. If run in three shifts, or even in two shifts, about 700 -800 pieces can be removed.
[610]
In the same two processes, in 2 P, in this, at most 200 pieces will be removed.
[617]
Right now you are looking at its pavilion, at this time this pavilion is getting worn out, with the diamond which is the main diamond, it is rubbed with it, the material which is made is also made from diamond powder.
[626]
The material which is being rubbed is not the big material above, this is also made from diamond powder.
[630]
After depositing diamond powder, it is rubbed again after depositing iron.
[634]
Because, only diamond can worn out the diamond, I say again and again, that only diamond can worn out the diamond.
[640]
This is also becoming a pavilion, and now, this pavilion, as it reaches the line, will become a pavilion
[649]
Till then it will come in that angle, in which the manufacturers want to make.
[656]
Now, you see Bruting, bruting means shaping, shaping the diamond.
[664]
isn't it?
[665]
By bruting we simply say that making a diamond a Girdle, making a Girdle and shaping it.
[669]
After bruting, now it goes to diamond, cutting and polishing. cutting polishing means, Faceting, Pale making, Facets are called Pale.
[679]
how many pails are there in a Round Brilliant Cut?
[681]
There are 57 pails, if there is a culet, then 58, then now this facet will be made.
[686]
So, the table we are looking at now, first the table will be glued, the table will be cut, however, the table is cut, it will be given a slightly better finish.
[705]
After the table is cut, now, this diamond mathala will be cut or Talia, anyone can cut, Talia means Pavilion, mathala means Crown.
[771]
Keep in mind that all the diamonds, and all the facets they have, all these facets are made by the artisans themselves.
[778]
By keeping this in a small tank, it is called angur, angur or tank. In English it is called tank, in Hindi it is called Angoor in Gujrati.
[785]
Putting on this angur, each facets is rubbed with their hands and, every time the movement of the diamond is seen.
[792]
Now what is this chaal ? What is Directions?
[794]
Like I was said earlier, I do not want to make the videos long.
[799]
So, I will make, I will make different videos on this topic so, that you can understand it in detail, but for now, let's understand in short.
[806]
That chaal means that there are eight directions, out of those eight directions, the diamond is best worn in any two directions.
[814]
Looking at those directions, the polish of the a diamond is to be maintained, the symmetry of the diamond is to be obtained, the weight maximum, which is given in the plan.
[821]
Think, how much is the value of an artisan, he is the biggest artist in the world.
[826]
This is what the owner of a diamond manufacturing company told me.
[830]
If there is any best artist in the world, then it is our Polishers.
[835]
So in this process, you see that the table is cut, all the faces of the crown are cut, all the facets of the pavilion are cut, and finally, a slight shine is given to its girdle.
[847]
It is called Rounding Machine.
[848]
A slight shine is given in the rounding machine.
[851]
As the shine is happening, you are seeing what kind of shine you have come in the diamond, so this shine is being given.
[861]
The roundness of the girdle is corrected, it is called a polished girdle.
[866]
As I have told you before, there are three types of girdle, in appearance, (1.) one is a polished girdle, (2.) second is a faceted girdle, and, (3.) third is Bruted girdle.
[873]
So, finally, the faceting and polishing are done on the Girdle.
[879]
Friends, tell me how did you like this video, definitely, I will make smaller and smaller videos, by elaborating these e videos.
[888]
This will make it easier for you to understand, how the 4 P machine works, how the serin machine works, how laser cutting works, what happens in polishing, how it happens.
[898]
That's all in this video
[899]
See you soon in the next video
[902]
Thanks again for watching this video,
