But it is not Moldavite, sorry.
Very unlikely it is natural glass, IMO. The only tektites found in Africa are termed ivorites which is a black tektite variety from the Ivory Coast strewnfield (Lake Bosumtwi Crater, Ghana). Found in the Côte d'Ivoire (Ivory Coast).
NOTE: Some tectites from the large Australasian field are fraudulently sold in Ivory Coast as being Ivory Coast tektites (the latter are extremely rare).
Furthermore, to my knowledge, the obsidian found in East Africa has been reported as black in the literature, not green.

Come on, be serious.
How can your specimen be positively identified, virtually, without optical testing performed by a professional gemologist/ mineralogist/ volcanologist?
Who is telling you it's not glass (except for the person who gave it to you). Green, man-made glass is high on the list of possibilities.
We have provided technical information of natural glasses found in your area and even the name of someone in Arusha to bring it to.

Very often the green glass fake stones and rough in east Africa started life as either Ndovu Beer Bottles in Tanzania, or Tusker Export Beer Bottles in Kenya. Look at the bottles in the link below.

Moldavite (Czech: vltavín) is a forest green, olive green or blue greenish vitreous silica projectile rock formed by a meteorite impact probably in southern Germany (Nördlinger Ries Crater) that occurred about 15 million years ago. It is a type of tektite.
Barbra already told you this!
Man made glass with man made tools is produced in many colors and forms(like:beer bottles) 1Bwana1 is telling you this based on his own personal experiences in your region, it also can be a man made glass creation by creative crafty individuals for the sole purpose of imitating a n appearance to a natural counterpart. Like Tsavorite, Peridot and others. I do not think this but tend to lean on the beer bottle possibility. I to do not read here where anyone said it wasn't glass. Do you understand that Moldavite is distinct based on its creation and common glasses made by us humans.

Hey please cool down. I wrote that I was checking it at a gemologist, he did the physical tests. He told me it was Moldavit... yet I understand now that it is a beer bottle.... I did not understand that they even fake that motherstone. A guy told me they sometimes even put the fake stones into the mine for a worker to be found.... ahhh silly world Thats the reason I was sceptical about bringing it to check in the first place...
In the meantime ive seen real tsavorite and it's a huuuge difference in beauty.

There is another source of tektite in Africa, the so-called LDG. Libya dessert glass. The glass is never clear, but always milky and cloudy.According to prevailing opinion, the impact glass (98% quartz), which shimmers in pale yellow to green, was formed when a meteorite impacted the eastern central Sahara around 28 million years ago. The crater is still unknown. The desert glass can be found in the very inaccessible dune landscape in the Egyptian-Libyan border area, the Libyan desert. Hence the name "Libyan glass". Already in the Paleolithic the stone was collected by humans, carved and was used as a sharp blade. The ancient Egyptians viewed him less pragmatically. It was considered very valuable and can be found on numerous cult objects, for example as a scarab, symbol of the sun god, on the Tutankhamun amulet. It is an absolutely admirable piece of jewelry.
