Big opalescent diamond shapes in grayish White, on the walls of a dining room. The diamond shapes are each 60cm tall and there are seven whole ones on the vertical plane, which fill the room. When the wall gets light, the diamond shapes appear with their pearlescent sheen, and they disappear in the shade. I painted this with mica powder mixed into a glaze. I protected it all with a coat of varnish. One can appreciate this I explain in the photos of the details.
