Lisa:
I saw this piece for sale and wondered about it. "A mace" is Murano slang for "with spots. " Marc Heiremans writes of them, "Various forms of this rather commercial series exist, from bold to boring." He pictures some on pages 57-8 of the Martens book. They don't have model numbers. Pina has some a mace bowls pictured on p.155 of "Italian Glass" valued at $300-$600. Some of the vases seem to go for very high prices, which surprise me. I like them, but they're nowhere near "Oriente."
All that said, I can't see spots in your bowl, although the spots are more obvious in some than in others. The irridescence dominates the photographs. I notice the seller calls it Venini. He can be occasionally quite optimistic, although, to be fair, I've bought some very nice pieces from him, including a very big square Barbino scavo bowl.
On balance, if you can see spots, I wouldn't rule out a mace and Martens.
