Description
Smoke Crystal Dark Marble is a compact and dense crystalline marble characterized by medium-fine grains. It features a deep smoky dark-grey background with subtle tonal variations ranging from medium grey to charcoal grey. The appearance is sometimes accented by fine lighter grey veins, cloudy crystalline patches, or delicate mineral speckles that contribute to its refined and elegant look. This marble is quarried in the Krastal region of Carinthia, Austria. Due to limited and intermittent quarry production, it is typically sourced from existing stock or secondary suppliers.
