Les Vergnes - Tarn Gros Grain

Derived from our Les Vergnes quarry, Tarn Gros Grain is a remarkable variety of Tarn granite. This exquisite granite showcases a stunning white to white-grey medium coarse grain, embellished with a consistent speckled appearance. Its allure is further enhanced by occasional black mineral concentrations, a result of its unique geological formation.
