Bohemian opaline rainbow swirl hand painted miniature vase - Harrach

This sweet miniature vase came from an eBay seller in Bulgaria. It features a swirl of pastel rainbow colours, more intense on the inside of the vase, as the outside has an opaline effect. There is handpainted decoration of a spray of what looks like cherry blossoms. It measures 5.7 cm tall & 5.4 cm across the gilded top rim. I think this is most likely Bohemian, late Victorian - Art Nouveau period.
