African Queen - Green Gem from the Heart of Africa.


Tanzanian Green Opal, also known as Prasopal, is a fascinating opal variety, which is found at Hanety Hill, north of Dodoma in central Tanzania in the mountains of East Africa.

A previously unknown and unusual deposit was found around 1960: the so-called Tanzanian Green Opal. A beautiful opal with an exceptionally vibrant body-color was brought to light.




The Tanzanian Green Opal is found relatively close to the surface and therefore can easily be mined by hand with pick and hammer.

However, the production has been and still is very low, and the rough is only found and offered very seldom and in very little quantities.
