Hello Juty, Impact Imports can supply you with this green onyx tile. This is actually very thin honey onyx tile glue laminated to white marble tiles, and the resin adhesive is green. So, the onyx appears green. We can supply you with this tile in different sizes. The price for a 20x20 tile (shown here) is $85 per tile. There is a 6-month lead time for this tile.
