This bowl is beautiful but a bit of a mystery. I am pretty sure it is Czech glass.
The bowl is 28 cm long to the points, 11.5 cm wide and 8.5 cm high.
It has pulled ribs below the points and on opposite sides an indented oval. This gives an amazing distribution of light and colour. The body colour is amber and this is citrine glass encased.
Not sure what else I can tell you but would be grateful for any information on designer, maker and date.
