Hi,
I would agree that your piece is probably Kralik. And, Kralik did produce a broad range of well documented fairy lamps (candle lamps is a better term). However, I do not believe it is correct to identify your piece as a fairy lamp. Fairy lamps of this style typically have a separate shade and candle cup. Unless I am mistaken, your piece is of one-piece construction. Below are a few fairy lamps of this style. These examples are from Fairy Lamps by Ruf. There are seemingly countless other variations and glass types of this style.

Your piece may simply be a "vase" or may have used oil and a floating wick if it was used as a lamp...but probably not a candle.
If you are interested in other Kralik fairy lamps, I would be happy to post a few known and probable examples for you.
