Victorian cased glass thorny rosebowl or tiny vase

I'm always happy to welcome thorny glass into my collection...just can't get enough of glass with quirky lumps, bumps, & spikes!
This cute little Victorian era rosebowl (or perhaps a tiny vase or even a toothpick holder) is made from two layers of cased glass - an unusual aqua green over an opaque white interior. It measures 7.5 cm tall, 6 cm across the four way crimped top rim, & 3.5 cm across the base, which has a snapped off pontil mark.
The thorns are not randomly placed as on most thorn vases - they are evenly spaced along every second rib. Tidy!
Could be Bohemian or English origin.
