Inclusion Plotter- Diamond Procssing

SECTOR: GEMS & JEWELLERY
SUB-SECTOR: Diamond processing
OCCUPATION: Diamond planning
REFERENCE ID: G&J/Q4203
ALIGNED TO: NCO-2015/NIL
Brief Job Description: Individuals on this job use different technologies such as
M-Box, Immersion Glass (IG) and Galaxy, based on Helium/Sarin software, to
view and manually or automatically plot different types of inclusions such as
cloud, surface cavities, blind spots, pin point inclusion, 3D, flat cracks, curved
cracks. Inclusion plotting helps the planner to determine that can be achieved in
the cut stone, which will determine its ultimate value. Hence, precision is
important in this job. Also known as Sorter or Plotter, the inclusion plotter plots
different types of inclusions in a diamond on the computer model.
Personal Attributes: The job requires the individual to have: attention to
details; good eyesight; ability to work for long hours in sitting position in front of
the computer; high level of concentration; and a lot of patience.
