The sink and faucet are Artistically fanstastic. the ring that lifts the sink off the countertop is artistically and functionally very satisfactory.  A gasket seals the drain in a vessel sink. I think I followed the installation instruction but I may have improperly installed that gasket so a small puddle about a 1/2 inch deep surrounds the drain. Obviously this will eventually leave a permanent water/mineral deposit surrounding the drain in the bottom of the sink. I have to figure how to correct this.
