Art glass vases with vaseline rigaree. Bohemian?

Art glass vases. I think these are Bohemian.

There is a blue pair. The applied rigaree is slightly different. One has much larger scallops. The purple example is very similar but has a heavier vaseline casing. The blue examples hardly glow under black light. The purple one glows much brighter.

The other 2 vases are opalescent with vaseline rigaree and applied flowers.

All of these were purchased separately with the exception of the pair of blue vases. I personally have not come across any other purple or blue vases before. My friend told me that purple and orange are the rarest colors in any kind of art glass.
