Aquamarine is a variety of beryl that is sky blue to sea green in colour.

Nineteen48’s aquamarine comes from artisanal mines around Ratnapura in Sri Lanka and the Tanga region of Tanzania (through the Moyo Gems project).

The Sri Lankan gems tend to be paler in colour and have few inclusions. The aquamarine from the Tanzanian miners can come in larger sizes with a deeper colour and fascinating inclusions.

Our aquamarine is not treated in any way to affect the colour or clarity.

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).
