Bohemian Art Nouveau cased glass vase with pulled zig - zag/marbled decor & silver rim.

Here is an interesting & unusual piece of art glass found on eBay AU. Not a bargain, but I thought it was too intriguing to pass up.
The vase is made from two layers of cased glass, clear over a pulled zig - zag or marbled type design in green, yellow, & white. The yellow threads contain cadmium & glow brightly under UV light, but sadly I could not properly capture this effect in a photograph.
The vase measures 20 cm tall, 5.8 cm across the base & 4 cm across the top rim, which is finished with a silver fitting. The seller did provide some information about the silver fitting:
Hallmarked London, capital L (probably 1886), and D.L (probably David Loebl of Schindler & Co) Schindler and Co, 9 Aldermanbury Avenue, London. Originally it was the London Branch of Schindler and Co, Gablonz (Germany), successively taken under control by David Loebl.
Personally, I think the date is a touch early, as the vase looks more likely to date later than 1886, more like 1900. Anyway, I'm here for the glass & not the silver, LOL!
The vase is in great condition with no damage, & I think most likely Bohemian origin but uncertain of an exact maker. Any sensible thoughts welcome!
