Responsibly sourced rubies from Sri Lanka and Tanzania. Rubies are corundum, and by definition, red, coloured by the presence of chromium.

Nineteen48 works directly with a trusted network of miners and suppliers to ensure all rubies are sourced through a fair and transparent supply chain.

Rubies are a popular gemstone, one of the "Big Three" of precious stones.

Red corundum is ruby, however there is no official classification for this. If you are looking for a red ruby or a pink sapphire, do broaden your search to look for both.

Nineteen48 rubies are responsibly sourced from Sri Lankan mines through a long-established network of local Sri Lankan miners, with whom strong and trusted relationships have been developed over the years.

The majority of the rubies here are from the Rubyfair project and were sourced from a community mine that operated near Mahenge in Tanzania. These stones have not undergone any heat treatment or other enhancements.

The Rubyfair project has now finished therefore the selection of Rubyfair gems on this website are the last remaining stones.

The town of Pelmadulla is located within the main gem mining area in Sabaragamuwa Province, Sri Lanka.

It lies south-east of the provincial capital, Ratnapura, which is the focal point of gemstone mining and trading activities.
