Rocks, Stones, and Pebbles

The famous Seiryu Stone is blueish grey in color with sharp jagged edges. Most of them consist of deep cuts and crevices within the stone itself. Seiryu Stones frequently have calcite veins within their layers, creating a great contrast from its brilliant blueish grey hue to its stripes of white veins. Small Stones .5 - 2lbs / 6" x 4" x 3.5" approx. Medium Stones 2 - 6lbs / 8" x 6" x 4.5" approx. Large Stones 6 - 11lbs / 11" x 8" x 6" approx.
