Bruter- Diamond Processing
SECTOR: GEMS & JEWELLERY
SUB-SECTOR:Diamond processing
OCCUPATION: Bruting and coning
REFERENCE ID: G&J/Q4505
ALIGNED TO: NCO-2015/NIL
Brief Job Description:The individual works with bruting machine and another
diamond or wheel (rotating in opposite direction to the diamond being bruted) or with
laser machine to give the rough diamond round and cone shapes. A bruter must be
careful while aligning the marking and setting parameter so that excess bruting does
not cause too much stone loss or sub-optimal bruting causes the girdle to disappear
at a later stage of processing. Also known as Bruter or Coner, the auto bruter provides
round girdle and cone shape to the sawed rough diamond with the help of bruting
machine/rotating wheel or laser machine.
Option 1 – Laser Bruter :
This unit is about giving the diamond its basic round and conical shape by using the
laser machine in which the doped diamond is placed on a platform, aligned and cut
using a laser beam. The objective is to ensure that a perfectly round girdle is formed
and the pavilion and crown is coned, while maximizing yield as per planned
dimensions.
Personal Attributes:
The job requires the individual to have: attention to details; good eyesight; steady
hands; ability to work in a process driven team; ability to work for long hours in sitting
position in front of a screen; high level of concentration; and a lot of patience.

Qualification Pack G&J/Q4505
Sector Skill Council Gem & Jewellery
Guidelines for Assessment
- Criteria for assessment for each Qualification Pack will be created by the Sector Skill Council. Each Performance
Criteria (PC) will be assigned marks proportional to its importance in NOS. SSC will also lay down proportion of
marks for Theory and Skills Practical for each PC. - The assessment for the theory part will be based on knowledge bank of questions created by the SSC.
- Assessment will be conducted for all compulsory NOS, and where applicable, on the selected elective/option
NOS/set of NOS. - Individual assessment agencies will create unique question papers for theory part for each candidate at each
examination/training center (as per assessment criteria below). - Individual assessment agencies will create unique evaluations for skill practical for every student at each
examination/training center based on this criterion. - To pass the Qualification Pack , every trainee should score a minimum of 50% of aggregate marks to successfully
clear the assessment. - In case of unsuccessful completion, the trainee may seek reassessment on the Qualification Pack
