Spinels occur in a huge array of colours. Alongside bright hues like scarlet, violet and ultramarine, they can also exhibit nuanced tones including lilac-grey, fuchsia-red and smoky blue.

Nineteen48 spinels are responsibly sourced from Sri Lanka, Tanzania and Myanmar. Nineteen48 works directly with a trusted network of miners and suppliers to ensure all spinels are sourced through a fair and transparent supply chain.

Spinels are a hard gem and good for everyday wearing jewellery.

Nineteen48 spinels are responsibly sourced from Sri Lanka. Many of the spinels come directly from their own artisanal mine near Kuruwita. Others are sourced through a long-established network of local Sri Lankan miners, with whom strong and trusted relationships have been developed over the years.

Tanzanian spinels are sourced through the Moyo Gems project in Tanga (north-east Tanzania). Some Tanazanian spinels are from the Rubyfair project, which has now completed, so there is a limited supply of these. 

Burmese spinels are sourced through our trusted partner, Natural Spinel Gem, who has a trusted network in Myanmar.

None of the spinels are treated in anyway.

The Rubyfair project was a community-run, artisanal mine located near the famous town of Mahenge in south-central Tanzania. The mine ran for a number of years and produced a good quantity of ruby and spinel. It has now ceased operation.
