Terms of Reference for Gemstone Identification Manual


Deadline:20 December 2022

Time Frame for assignment: 8 days

Reports to: Project Officer

1.Background and Introduction

A public interest organisation which is into natural resources governance and environmental justice work seeks to hire a consultant to develop a gemstone identification manual. The organisation is implementing a five-year project with the objective of nourishing the gemstone value chain to capacitate women with marketing and trading skills. This is being done to reduce illicit financial flows of gemstones through gemstone artisanal small-scale formalization, improve sustainable trade, value chain, value addition and beneficiation for improved livelihoods. This is towards result-oriented participation of marginalized groups of mining communities in the gemstone trade and value chains. A project baseline survey was convened and established a gap in identification and valuation of gemstones, Artisanal and Small-Scale Mining (ASM) are producing stones they do not know the name, characteristics, and value.

Most of the coloured gemstone mining in Zimbabwe is performed by ASM; workers who use rudimentary technology, such as picks and shovels, to mine for minerals that are typically found in shallow deposits. These ASM are mostly farmers who alternate between farming and mining to provide for the household hence they lack adequate knowledge on gemstone mining, identification of type and its value, which places them at a disadvantage when selling their product, hence they are short-changed by buyers. The traditional classification of gemstones begins with a distinction between precious and semi-precious. In modern usage, the precious stones are diamond, ruby, sapphire, and emerald, with all other gemstones being semi-precious. Gemstones are categorised by gemmologists, who describe gems and their characteristics using technical terminology specific to the field of gemmology.
