ℹ️
True Geology: Gabbro
Galaxy Black Pearl is commercially sold as granite, but it is geologically a gabbro. This distinction matters because true geological classification determines the stone's actual physical and chemical properties — which affects how it performs, how it should be maintained, and how it reacts to acids and moisture.
