This iridescent blue glass jardiniere (or cache pot) has a pewter frame by the well known maker Friedrich Van Hauten of Bonn, Germany (shield on the right of the serial number in the second pic is the coat of arms for Bonn).
Van Hauten made ceramic steins in pewter frames, and during the Art Nouveau period (circa 1900 and later) also outsourced their pewter mounts to glass makers like Loetz and Kralik.
This jardiniere is 5.5in high x 8in diameter. It isn't by Loetz, and is unlikely to be Kralik. As SteveS. points out below the colors and the stretch glass pattern could be by Rindskoff, Poschinger or one of many other Bohemian glass houses from this period.
It has a strong iridized effect that's hard to capture in a pic, it's best seen in the pictures of the base.
Once the blue glass is back illuminated the iridescent effect almost disappears, but that blue background color is very attractive in itself, especially when it's in a window illuminated by sunlight.
Still open to advice from anyone who can tentatively or definitively identify the glass maker.
