There's a vase listed on eBay ...
https://www.ebay.co.uk/itm/Art-Deco-Miniature-Blue-Glass-Vase/283440972571which resembles the OP's vase. Is it the same? If so, it reminds me of some features of some Hermanova glass. I can't find the exactly matching pattern but some of the details of the OP's vase resemble some of the features seen in items contained in the CD (Hermanova, up to 1958 catalogue, page 6) accompanying the book "SKLO Union: Art Before Industry: 20th Century Czech Pressed Glass" by Marcus Newhall (Hardback, 2008).
