Black basalt pebble, graded to a strict 6mm. Naturally rounded by water, not machine-tumbled — a flat, deep black finish that a tumbler can't reproduce. The single even grade means consistent exposure in pool interiors and exposed aggregate, and a clean even bed in landscaping. A genuinely rare stone that few yards carry.
