This triangle centerpiece bowl was designed by Flavio Poli in Murano, Italy. It has a beautiful green glow and the amethyst changes colors with the light. I believe this bowl dates to the 1950's. It has scratches on the base, a bubble at the surface of bowl and some scratches that can be polished out, if desired. There is calcification residue in the bottom of bowl.I have tried all the natural remedies to remove, but to no avail. I believe CLR is needed. I will leave that to you.
