My Easter Egg - Mystery

I had the good fortune to purchase this vase around eight or nine years ago at a very reasonable price from a local collector. The seller didn't know what it was, but thought it might be Loetz. I did not believe the Loetz attribution, but it was a very nice and well crafted object, so I bought it anyway. Due to the pastel colors and ovoid shape, I affectionately call the piece, "The Easter Egg".

The vase stands about 11" tall and is about 4.5" in diameter at the widest. The construction is of cased glass with an inner layer of cream colored glass. The next layer is composed of a variety of pastel yellows, purples, and aqua colors. This is cased in a clear layer with an overall metallic iridescence. To me, the style gives me the impression of brush strokes in an impressionist painting of springtime flowers. The tricorn rim has been carefully worked and folded. One can see the tool marks in the 2nd close-up photo where the lobes were pulled. The base has a wonderful polished pontil, and from the slide marks and fine wear, one can see that the vase has some age. Since there are no import marks, I would place this in the 1900-1915 era.

Over the years, a number of collector friends have offered opinions as to the maker, but I have never been able to definitively attribute this vase. I won't mention these here so as not to cloud your opinions. Your help and thoughts would be greatly appreciated as to the origins of this beautiful object. Cheers!
