PURPOSE OF THE UNIT STANDARD 
This unit standard is useful for people who are required to examine the internal characteristics of rough diamond gemstones.

Learners credited with this unit standard are able to:
  • Identify the need for putting a window on a rough diamond gemstone.
  • Determine the location(s) where the window(s) must be placed.
  • Issue instructions for the opening of a window(s) on a rough diamond gemstone.
  • Conduct post-window placing reconciliation, checking and security activities.

    The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and contribute to the upliftment and economic growth of the mining and minerals sector, particularly in the aspect of beneficiation.

    This unit standard is intended to promote general skills, knowledge and understanding of processing of diamond gemstones in the mining and minerals sector in order to ensure knowledgeable and informed workers. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are already competent in:
  • Requirements for security of diamonds.
  • Use of a loupe for advanced examination of diamond gemstones.
  • Identifying the characteristics of rough diamond gemstones.
  • Identifying the grain in rough diamond gemstones. 

  • UNIT STANDARD RANGE 
    The scope and context applies to the conversion of rough diamond gemstones into cut and polished diamond gemstones for sale into local and international markets. 

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Identify the need for putting a window on a rough diamond gemstone. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The circumstances under which a window would be placed on a rough diamond gemstone are explained in relation to assessing the internal characteristics of a diamond gemstone. 

    ASSESSMENT CRITERION 2 
    The implications of placing windows on rough diamond gemstones are explained in terms of opening light access to improve examination. 

    ASSESSMENT CRITERION 3 
    The risks associated with placing windows on rough diamond gemstones are explained in terms of potential damage or limiting the potential processing opportunities of the gemstone. 

    ASSESSMENT CRITERION 4 
    The consequences of deviating from workplace specific practices are described in terms of potential impact on health, safety, equipment, products and profitability. 

    SPECIFIC OUTCOME 2 
    Determine the location(s) where the window(s) must be placed. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The examination of a rough diamond gemstone indicates the need for further examination to ascertain the internal characteristics of the gemstone. 

    ASSESSMENT CRITERION 2 
    The rough diamond gemstone is cleaned or boiled to assist in assessing the characteristics of the gemstone. 

    ASSESSMENT CRITERION 3 
    The assessment of the cleaned rough diamond gemstone is made and the area(s) requiring further examination of internal characteristics is/are identified. 

    ASSESSMENT CRITERION 4 
    The area(s) where the window(s) is/are to be placed are indicated and the reasons therefore are explained in terms of assessing the desired internal characteristics of the gemstone. 

    ASSESSMENT CRITERION 5 
    The risks associated with opening a window on the particular gemstone are explained in terms of physical consequences to the gemstone and the ability to examine the interior of the gemstone. 

    SPECIFIC OUTCOME 3 
    Issue instructions for the opening of a window(s) on a rough diamond gemstone. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    An appropriate parcel is selected and the selected diamond gemstone is identified and recorded in the parcel. 

    ASSESSMENT CRITERION 2 
    The window opening instructions are clearly marked in the parcel and checked in accordance with workplace specific procedures. 

    ASSESSMENT CRITERION 3 
    The parcel containing the gemstone is sent for window opening in accordance with workplace specific procedures. 

    ASSESSMENT CRITERION 4 
    The returned parcel is received in accordance with workplace specific procedures, and examined to see that the window(s) have had the desired effect for examining the internal characteristics of the gemstone. Remedial action is taken, if necessary, in terms with workplace specific procedures. 

    ASSESSMENT CRITERION 5 
    Remedial action is taken in accordance with workplace specific procedures. 

    SPECIFIC OUTCOME 4 
    Conduct post-window placing reconciliation, checking and security activities. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    After window-opening examination, diamond gemstones are returned to the appropriate storage facility/receptacle. Rough diamond gemstones received are reconciled to the parcel(s) received. 

    ASSESSMENT CRITERION 2 
    Good housekeeping is exercised after indicating window opening. 
    ASSESSMENT CRITERION RANGE 
    Good housekeeping must include:
  • Clean hands, equipment and accessories.
  • Diamonds and parcels are secured in the appropriate facilities.
     

  • ASSESSMENT CRITERION 3 
    Diamond gemstones are accounted for after indicating window opening in terms of the workplace security system.
