Gramazini

What Gramazini does

Gramazini Granitos e Mármores Thomazini is a privately-held Brazilian natural stone extraction and processing company founded in 1992, headquartered in Barra De São Francisco, Brazil, with 501-1000 employees. The company operates five wholly-owned quarries across the Brazilian states of Ceará, Minas Gerais, Bahia, Paraná, and Espírito Santo, organized through operating subsidiaries including Gramazini Mineração F1, Mineração Thomazini F24, and DJ Granitos F8. Gramazini extracts and processes granite, marble, quartzite, and quartz materials, offering a portfolio that includes proprietary materials such as Nacarado, Madre Perola, Montebello, Brazilian Black, Virginia Black, Montana White, and Ankara, available in polished, honed, leather, brushed, and flamed finishes.

The company's business model combines raw stone block sales, finished slab sales, and custom fabrication services for applications including countertops, flooring, wall cladding, facades, vanity tops, fireplace surrounds, and tabletops. It serves a horizontal mix of customers — architects, interior designers, construction contractors, and homeowners — through direct sales via in-house sales executives, an online product catalog, and participation in major industry events such as Marmomac Brazil 2025 and Vitória Stone Fair. Pricing is quote-based with no public pricing disclosed.

Gramazini's vertical integration from quarry ownership through fabrication is its primary structural differentiator, supplemented by sustainability initiatives such as solar energy at the Linhares facility and compliance with Brazilian wage transparency regulations. The company shows no public listing, venture funding, or significant M&A history, operating as a privately-controlled ornamental stone enterprise with national Brazilian market focus and limited but documented international sourcing (Virginia Black diabase from the USA).
