I have 3 free form shaped cobalt blue (one is slightly purple) cased in thick clear glass vases (or could be candlestick holders) that I need ID help with. They range in height from 3.5" to 4.5". I was thinking they may be Orrefors or Skruf but then again they could be from one of the Italian glass works. Two of the vases have similar polished bases while the more purple of the three has an indented pontil mark. Any help unraveling this mystery would be greatly appreciated.
