Sapphire Facet Round Pink

Responsibly sourced sapphires from Sri Lanka, Tanzania, Australia and Malawi. Nineteen48 works directly with a trusted network of miners and suppliers to ensure all sapphires are sourced through a fair and transparent supply chain.

Sapphires are a popular gemstone due to the spectrum of colours they come in. From traditional rich blue to pale azure, you can also find violet, yellow, green, teal, orange, pink... any colour except red.

Sapphires are part of the corundum family.

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 sapphires are responsibly sourced from Sri Lanka and Tanzania. Many of Nineteen48's sapphires come directly from their own artisanal mine near Kuruwita.
