I have two more specimens I would like help on. The large vase stands 28cms in height, is very heavy, has a smooth polished base, no names etc, the bottom portion of the vase is lumpy. The colour is blue and mauve and possibly contains alexandrite. The small, vase is 20cms in height, polished base, and is also blue and mauve. I assumed them to be Zelezny Brad SkloI ? The small one maybe Caithness but thought the base was not right. I have scoured my usual references including the new ones directed to by GMB contributors without luck. Any ideas. Thanks
