Anza Gems

ANZA gems creates a transparent, traceable journey from the mines of East Africa to you. The journey of an ANZA gem is not only a rich story, but also creates a circle of development beginning with fair trade prices paid in East Africa, continued by supporting independent artisans who facet our gems and create our custom jewelry, and ultimately reinvesting 10% of sales to education and other initiatives supporting gem communities. This includes education at the primary level, as well as at the jewelry trade level with vocational schools teaching Africans marketable skills of gem cutting, grading and sorting.  Our goal is to have East Africans facet their own gems, design their own jewelry, and fully participate in the global gemstone trade.
