I looked through my photos and the photos on emaryllis.com. I don't see anything which is a good match for your photo. Do you remember where you got it? If you can email a photo to the source, they may be able to ID it based on what they were selling at the time. To complicate things, some companies sell bulbs as "exclusive to the grower." The grower gives them a name, but they are unregistered at that time. That makes it very difficult to later ID them. If the bloom is about 4 inch across the face, it could be Donau, registered in 1994. If it is larger, it could be Lagoon, registered in 2013. I am hesitant to make a guess in this case.
