I think this vase is by Royal Brierley but I can’t be sure as it is unmarked and has no label. It has lovely blue and gold detail on a rich blue base and  is in very good condition, just one tiny rim chip as shown . It  stands 3.75” high and 4” diameter . Please note glass is only covered for breakage by royal mail if sent via special delivery, so other methods at the  buyers risk. Will be carefully packed.
