Crystal candle holder bud vases?

The mushroom is about 4.75" high and the spindle is about 4.5" high. Both have smooth tops and textured bodies, but the bottom of the spindle is smooth as is the bottom of the mushroom cap. The cavity in the mushroom is about 3.75" deep and in the spindle about 3.5" deep. Both Blenko and Kosta Boda made mushroom shaped candle holders and Finnish maker Iittala has similar spindle candle holders in their Festivo line designed by Timo Sarpeneva in the 1960s, but none I can find by any maker have such a deep cavity. All of the others I can find have a cavity just deep enough to accommodate a candle securely. The cavities in these are so deep that I wonder if they might be dual purpose candle holders and bud vases. There is a surprising similarity between some of Blenko and Kosta Boda's products, but neither have anything with this deep cavity. Does anyone know who made these? I am grouping them together because I have the same questions about both and they may be by the same maker. They were found separately, the mushroom recently and the spindle a few years ago. I also recently found a couple of heavy UFO shaped crystal candle holders (not shown) that remind me of these, though they are only about an inch thick.
