This is a Bohemian art glass vase, looks like Vaseline glass, however it is not so please don't make a purchase thinking it is Vaseline glass; I believe the layers of other glass make the yellow interior appear to be Vaseline. The date is circa 1910.
The glass is beautifully cut, with a tulip or other flower on the front and back, and a star on each side. The glass is brown cut to clear and the yellow glass is on the inside. I suppose the brown might actually be a version of red, but it looks brown to me so that is what I am calling it.
The vase is quite beautiful and unique. It is 6 7/8" high and 4 7/8" wide at the mouth.
Be sure to look closely at the photos where I show the bottom from the side as from that view you can really see the brown top layer, then the clear layer, and then the yellow glass on the inside.
The bottom underside is also cut in a ridge design, with the brown over the clear. On the bottom sides the brown is cut to show the clear glass in oval insets, with the flowers and stars above, finishing with a scalloped design towards the top.
The rim is polished flat; I do not see any beveling on the sides.
There is a small area on the outside rim that is grazed or nibbled, that I show in a close-up photo. There are no other nicks, chips or cracks. There are a few tiny air bubbles in the glass.
