If you’re new to the rough diamond market, trying to understand how uncut diamonds works and how to trade with them legally can be incredibly difficult. You can’t just dive in, through the lessons you will learn understand the entire complex process.
This course teaches you how to sort and evaluate a parcel of rough diamonds into different categories according to various criteria such as size, colour, clarity and shape. This course focuses on both practical and theoretical knowledge.
As there is no regulated set of criteria to evaluate them, therefore it is difficult to assess their price without the technical ability to do so.
