Black Galaxy Granite — Samples, Technical Data & Applications
A premium black granite from Andhra Pradesh, India. A uniform pure black ground is densely speckled with shimmering golden-copper mineral flecks, like a starry night sky. As a granite it is far harder and more abrasion-resistant than marble — ideal for countertops and high-traffic flooring.
