Hi Kathleen, is not a Geode bowl (a geode is like a melon cut in half - is how i would describe it). Love the Green & Amber pieces. I don't think this is a Seguso piece. Many murano companies (and other countries/companies) copied this colour design, and unfortunately, I don't think we can peg this one to any specific maker!
Roughly a third of my collection is Green & Amber pieces, only a few are by Seguso and the rest are from a wide range of other Murano makers, mostly unidentifiable but still definitely by some quality makers! (Maybe one day someone will pop up here with pieces that have labels on them or that have been signed!) :thup:
