Faberge, as in Eggs, made these perfume bottles with Limited Edition Glass Eggs that came in big beautiful velvet boxes. I have several of them, although the others are marked, this one came in an egg and likely the egg was marked. The stopper looks like black but if you hold it to the light in is a deep dark green. It is in great condition. The stopper isn't a tight fit and sits a bit high. I checked my two other Faberge bottles and they aren't a tight fit either. Not like a Czechoslovakian perfume bottle top fits, which is tight and secure. It's gorgeous glass. Maybe you have the crystal egg that is looking for the perfume bottle!
The perfume bottle has no chips or cracks and is lovely. It stands 4 1/4 inches tall.
