Art Nouveau Kralik mother of pearl glass squat vase

Last year I acquired a small version of this vase, so it was a pleasant surprise to stumble upon a larger one of the same decor.
The vase measures 11 cm tall, 14 cm across the flat, flared out top rim, & 9 cm across the base.
It is made from two layers of cased glass, clear with an iridised finish over an opaline white interior.
Third photo compares it with the smaller sized one, which has a warmer tone to the iridescence, & the embossed pattern is also a touch more prominently raised.
Typically attributed to Kralik. Bohemian origin early 1900s.
