My better half brought this home from a thrift store for me today, and it is not like anything I have really seen before. It is a small geometric cut vase in clear, with a very thin sommerso layer inside the piece. The Sommerso layer is one layer that fades from blue on one side of the vase to a very light vaseline green on the other side. I can not recall seeing a piece like this before. I am used to seeing two colors in two layers and not in one. The vase has appropriate age wear on the underside and I would say it dates to the late 50's or early 60's. It stands 6 inches tall and is very well done. The internal layer of glass glows very brightly under black light on the light green side, and fades out as you get further into the blue portion of the layer. I am looking for all the help I can get with this one.
The colors are most accurate, at least on my monitor, in the 3rd image.
It strikes me as Scandinavian and not Italian, but I could be way off base... Any thoughts?? Anyone seen this vase before??
