Bohemian Art Nouveau purple iridescent glass vase - Kralik Honeycomb Panel

Here's an interesting & unusual Art Nouveau glass vase which I won on eBay AU last week.
It is made from purple/amethyst glass with an iridescent finish. Measuring 17.8 cm tall, 5 cm across the cut top rim, & 8 cm across the base, it features four panels of a moulded pattern which I would describe as "cellular", alternating with four plain panels, separated by ribs. This creates a rather striking design on the base.
Thanks to Peggy & Craig I can now attribute this as an example of Kralik Honeycomb Panel.
