Bought this on E-Bay Seller claimed this to be VINTAGE MURANO BLUE CASED GLASS

I recently purchased this vase from a seller on E-Bay. The description follows:

Here is a vintage vivid blue cased glass vase by Murano. The item has 2 clear handles, a clear glass base, and a clear glass flower applied over an end of days pattern. It has pontil on the bottom. It measures 10"/ 26cmH x 4.5"/ 11cmD (top) x 3.5" 9cmD (base). The item is in good condition, no chip / scratch / cracks/ nibbles. No backstamp or label

Since I know almost nothing about Murano glass, I believed the description. However, the glass on this vase is not nearly as thick as the other Murano pieces I purchased. The vase is white on the inside and blue on the outside. The white and blue glass look almost more "formed" or "sandwiched" together rather than "blending" together like the Murano. Also, the glass is thinner and the ruffles are not as pronounced as what I have observed on some other pieces. The image I posted here is the one that was used by the seller on e-bay.

It would be very helpful if any glass experts could provide me with your thoughts. Thank you.
