Question 1

When Planning a rough diamond the inclusion should be Is it right to plan a rough diamond with a Inclusion in the Centre of the table
A)in the centre of culet
B)in the centre of table
C)beneath the crown facets near the girdle
D)in the kite facets

Accepted Answer

When planning a rough diamond, the inclusion should ideally be positioned beneath the crown facets near the girdle. This placement allows for the possibility of removing the inclusion during the cutting and polishing process, or minimizing its visibility in the finished diamond. Placing an inclusion in the center of the table or culet, or in the kite facets, would make it more visible in the finished product, potentially reducing the diamond's value and appeal.

Question 2

What is the primary aim of a computer planner
A)optinum plan to get the maximum value of the rough
B)calculate several alternative projections of shape
C)calculate several alternative projections of clarity
D)all of the above

Accepted Answer

The primary aim of a computer planner in the context of diamond cutting or similar applications is to achieve multiple objectives, including creating an optimum plan to maximize the value of the rough material, calculating several alternative projections of shape, and considering various projections of clarity. These tasks collectively aim to ensure the best possible outcome from the raw material, making "all of the above" the correct choice.

Question 3

What precautions are to be taken by planner
A)no inclusion at the culet
B)no cavity on the crown and table
C)not sure about the inclusion go for window opening first
D)all of the above

Accepted Answer

All the options listed are precautions that a planner should take when planning a diamond. Inclusions at the culet, cavities on the crown and table, and uncertainty about inclusions necessitating a window opening are all concerns that need to be addressed to ensure the quality and integrity of the final gemstone.

Question 4

Why is computer rough planning done in a rough diamond?
A)to capture inclusions & blemishes
B)to capture the diamond colour
C)for removing the blemishes
D)for cutting the diamond

Accepted Answer

Computer rough planning in a rough diamond is primarily done to capture inclusions and blemishes, which helps in determining the best way to cut the diamond to maximize its value and beauty while minimizing the impact of these imperfections.

Question 8

Valuation in software can be decided by
A)4c
B)grading laboratory
C)company norms
D)all of the above

Accepted Answer

Valuation in software can be influenced by a variety of factors including the 4C's (cost, customers, competitors, and capabilities), grading by a laboratory, and company norms. These elements can all play a role in determining the value of software.

Question 9

If required natural skin or extra facet should be placed in which part of the pavillion
A)in girdle
B)on culet
C)between facets
D)between lower girdle facets

Accepted Answer

The answer of If required natural skin or extra facet...

Question 10

What do you mean by Planning
A)analyzing of rough diamond for getting best polished diamond with the best clarity grade out of the rough stone.
B)analyzing of rough diamond for getting best colour with the best clarity grade out of the rough stone.
C)analyzing of rough diamond for getting best symmetry with the best clarity grade out of the rough stone.
D)analyzing of rough diamond for getting best proportions with the best colour grade out of the rough stone.

Accepted Answer

Planning in the context of diamonds refers to analyzing a rough diamond to determine how to cut it to achieve the best possible polished diamond, focusing on clarity and maximizing value.

Question 11

What is the importance of Planning a rough Diamond
A)manual planning
B)planning on softwares to get best yield and value
C)direct 4p
D)none of the above

Accepted Answer

Planning on software for a rough diamond is crucial as it helps in determining the best possible way to cut and polish the diamond to maximize both its yield and value. This involves analyzing various cutting options to find the most profitable outcome.

Question 12

What is the importance of Planning a rough Diamond on software
A)fast
B)more options choice
C)inlusions plotting
D)all of the above

Accepted Answer

Planning a rough diamond on software is important because it allows for a faster process, offers more options for how the diamond can be cut, and enables the plotting of inclusions, all of which contribute to maximizing the value and quality of the final diamond.

Question 13

For computer planning the Planner has to take into consideration
A)stress
B)colour
C)coating
D)blemish

Accepted Answer

Stress is a factor in computer planning related to the performance and reliability of computer systems under various workloads and conditions. It's important to consider how a system will perform under stress to ensure it meets the necessary specifications and user expectations.

Question 14

Why is stress checked in a rough diamond?
A)to plan for saving loss accrdingly while cutting
B)to polish the diamond
C)to check the colour of rough diamond
D)to check the shape of rough diamond

Accepted Answer

Stress is checked in a rough diamond to plan for saving loss accordingly while cutting. This involves identifying any internal stresses or flaws that could affect how the diamond should be cut to maximize both its size and quality, thereby minimizing waste and loss.

Question 15

Stress is seen in the diamond in which colors?
A)red
B)rainbow colors
C)green
D)blue

Accepted Answer

Stress in diamonds can manifest as rainbow colors, which are seen when light is dispersed by the internal structures under stress, creating a spectrum of colors.

Question 16

Stress is observed in a diamond with which instrument
A)polariscope
B)10 x eye glass
C)m-box
D)microscope

Accepted Answer

A polariscope is used to observe stress patterns in gemstones, including diamonds, by analyzing how they interact with polarized light.

Question 17

If UV flourescence is there in a rough diamond, what will be its effect on the colour of the polished diamond
A)colour will be one grade down
B)colour will be one grade up
C)no change
D)none of the above

Accepted Answer

UV fluorescence in a rough diamond can cause a blue tint in the polished diamond, resulting in a lower color grade.

Question 18

Diamond flouresces in which colour under UV
A)pink
B)blue
C)orange
D)none of the above

Accepted Answer

Diamonds can fluoresce in a variety of colors under ultraviolet (UV) light, but the most common fluorescence color is blue. This is due to the presence of trace amounts of boron within the diamond's structure.

Question 19
