Nature's Geometry

Nineteen48’s golden rutilated quartz and emeralds are responsibly sourced from Bahia, Brazil, through a valued partnership with Nature’s Geometry, run by Brian Cook.

Brian has spent over 30 years working closely with the local community in Carnaíba, pioneering efforts to formalise artisanal mining operations and securing the community’s rights to mine in the region.

Nineteen48 is proud to support this ongoing collaboration by promoting the extraordinary gemstones discovered by these dedicated miners.

Nature’s Geometry exemplifies a balanced approach to responsible sourcing—providing exceptional gemstones while actively investing in community-building and sustainability.

Their work in Brazil is more than a mining initiative. It represents a model for socially responsible and environmentally conscious engagement within the gemstone industry.
