Two worlds— quarrying and research, and the marketing of granite blocks—come together.
This vision gave rise to Società Promozione Graniti (SPG), a company that places the granite block at the heart of its mission.
SPG works directly with quarriesthat supply materials designed to stand the test of time:
Nero Impala, Virginia Black, Nero Belfast, and Verde Oliva.
Granites selected for their texture, reliability, and consistent quality.
In addition, the company is built on a solid and well-established organizational structure, with dedicated testing facilities in India and Brazil and an international materials research network operating in the world’s major mining regions.
