Intrigued but this bowl

This is a large pasta-size bowl and very unique. There are colors of irradescent brown, seaweed green, torquise and gold. There appears to be a konch shell sitting on the edge of the bowl and a beautiful raised sun face in the middle of the bowl. The bottom of the bowl is stamped but I can't make it out. There is however what looks like L:KO which is very legible.
