PURPOSE OF THE UNIT STANDARD 
This unit standard is useful for people who intend following a career in the diamond processing sector and who are required to prepare makeable diamond gemstones for processing. This process is known as preparation.

Learners credited with this unit standard are able to:
  • Identify the equipment and tools used to prepare diamond gemstones and describe their application.
  • Demonstrate knowledge of the structure of diamond gemstones and the implications for polishing.
  • Set and clamp diamond gemstones for preparation.
  • Prepare diamond gemstones for processing.
  • Conduct post-preparation cleaning, 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 the diamond processing industry in the mining and minerals sector in order to ensure knowledgeable and informed workers.
