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 facet the girdle on diamond gemstones. It is for persons required to polish facets on the girdle of sawn and makeable diamond gemstones in order to make the stone round, using machinery. This process is known as girdle faceting - not to be confused with girdle polishing.
Learners credited with this unit standard are able to: 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. |
