iridescent glass in Illuminations Store

[Kallen]

Last year on the Dawn Princess, I purchased an iridescent clear glass sea shell in the Illuminations store. They had a whole selection of various sea creatures (anemone, starfish, abalone, etc.) in a small glass case just inside the entrance to the store. Can anyone tell me who the maker of these shells is? If anyone is going on a Princess ship in the near future can they go into the store and see if they are still being sold? I'd really like to get another next year.

I was thinking they were Swarovski crystal but an internet search is not showing up what I remember.
