We sell aquascaping and aquarium stone : Black Seiryu, Ohko/Dragon Stone, and Texas Holey Rock/Honeycomb Limestone. We also sell Suiseki pieces, and Bonsai decorative materials.
Our bulk rock prices are the lowest price shipped per pound.
We take great pride in the quality of our rock. Noone equals our quality at any price. It is all cleaned and processed multiple times to perfect the sheen of each stone type. Some of our Black Seiryu is like shiny black coal since it is processed multiple times. Other pieces are frosted like icing. We are one of the few who sell pre-washed, Tank Ready Ohko/Dragon Stone.
