Facets and cabochons ex tanzania,zambia southern africa

I have a collection of around 1000 facet and cabochons stones, which may be useful for courses/students.

they include tourmaline, citrine, amethyst, topaz, quartz, ruby, opal, rhodolite, garnets, sapphire, .

They have been cut by local tanzanian artisans so quality is probably not grade A but still beautiful
