Beryl Facet Step-cut Emerald (shape) Yellow

Of the beryl family gemstones, Nineteen48 offers mostly aquamarine and colourless beryl (goshenite). Neither of these materials is routinely treated in any way.

We also have a few examples of emerald in our inventory.

Moyo Gems is a pioneering, miner-to-market, gemstone collaboration in East Africa.

Nineteen48 is one of the commercial partners working with the women artisanal gem miners and their male allies in Tanzania and Kenya to deliver their gemstones to the international market.

We source our Moyo Gems specificially from miners in various communities in the Tanga region in north-east Tanzania, all of whom are members of the Tanzanian Women Miners' Association (TAWOMA).
