Certificate in Gemmology
The Certificate in Gemmology provides foundational skills in gemstone identification, grading, valuation, and the gemstone trade. Students learn to identify precious and semi-precious stones, understand gemstone properties, use gemmological testing equipment, and assess gemstone quality. The programme is designed for individuals seeking entry-level positions in the gemstone industry, mining sector, jewellery trade, or as independent gemstone dealers.
Students develop competencies in gemstone identification, visual inspection, use of gemmological tools (loupe, microscope, refractometer, spectroscope), gemstone grading, and basic valuation. The curriculum covers gemstone formation, mineralogy basics, gemstone varieties found in Kenya, testing methods, grading standards, and the gemstone trade. Practical skills in gemstone identification and grading are emphasised through laboratory sessions.
Kenya is a significant producer of gemstones including tsavorite, ruby, sapphire, tourmaline, and aquamarine, with Taita Taveta County being a major gemstone mining region. The gemstone industry contributes to mineral exports and local livelihoods. The growing interest in Kenyan gemstones in international markets, the development of value addition in the mineral sector, and the need for professional gemstone assessment create demand for trained gemmology personnel.
The programme combines classroom lectures with laboratory sessions and field visits to gemstone mines. Students practise gemstone identification, use testing equipment, examine specimens, and visit mining sites in the Taita Taveta region. Teaching methods include practical demonstrations, laboratory exercises, specimen analysis, and field-based learning.
Graduates find employment as gemstone identification assistants, mining company technicians, jewellery trade assistants, or gemstone dealers. The certificate also provides a pathway to diploma programmes in geology, mining, or gemmology. Some graduates establish small gemstone trading or lapidary businesses, adding value to rough gemstones through cutting and polishing.
This programme is ideal for KCSE graduates with an interest in gemstones and the mineral sector, as well as individuals already working in mining or jewellery trade who seek formal gemmology qualification. The accessible entry requirements make it suitable for those exploring gemmology as a career before committing to diploma or degree-level studies.

A day as a student
A typical day combines morning lectures on gemstone mineralogy or identification theory with afternoon laboratory sessions. Students examine gemstone specimens, use loupes and microscopes, conduct refractive index tests, and practise grading. Field visits to local gemstone mines in Taita Taveta provide real-world exposure to gemstone extraction and the mining trade.
The trade offs
In its favour
- Kenya is a significant gemstone producer, with Taita Taveta County being a major mining region, providing unique location advantage.
- Skills enable entrepreneurship in gemstone trading and lapidary work with relatively low startup capital.
- Provides a pathway to diploma and degree programmes in geology, mining, or gemmology.
Against it
- The gemstone industry in Kenya is relatively small and niche, with limited formal employment opportunities.
- The programme is offered at only one university, limiting accessibility.
- Fee data for this specific programme is not publicly available; prospective students should contact TTU directly.
What it costs

What it costs, and where

Common misconceptions
Gemmology is just about identifying diamonds.
Gemmology covers a wide range of precious and semi-precious stones including tsavorite, ruby, sapphire, tourmaline, and many others found in Kenya.
There are no career opportunities in gemmology in Kenya.
Kenya's gemstone industry, particularly in Taita Taveta County, creates opportunities in mining, trading, valuation, and jewellery manufacturing.
Gemmology requires expensive equipment to practise.
Basic gemmological tools like loupes and tweezers are affordable, and the programme provides access to laboratory equipment for training.
The gemstone trade is only for large companies.
Individuals can participate in the gemstone trade as dealers, lapidary artists, or consultants, with many small-scale operators in Kenya's mining regions.
