Beautiful antique blue iridescent art glass vase by Kralik. This was clarified by the founding member of "Czech Out Bohemian Art Glass" on Facebook.
Rare twisted pinch design that plays well in the light. No chips, cracks, or water damage. A couple small flea bites at the rim as shown in photos. Stunning piece with show stopping lapis lazuli coloring! Glows green under 365 UV black light related to manganese in the glass.
