Both 681E and 681R are premium natural slate products both sourced from Bai Zhu Xia Quarry, a vast mining site housing two distinct slate veins. One vein produces slate with a deep blue-black tone, while the other yields a unique gray-green variation. To differentiate these color profiles, we assign identifiers “E” (for blue-black) and “R” (for gray-green) based on their specific extraction zones within the quarry. Slate blocks sharing the same identifier (E or R) are processed and packaged together to ensure consistent color and texture across every batch.
