The glass clarity is excellent and the Opalescence is very good. Beware of reproductions in this pattern. Wright reproduced this vase in plain colors without Opalescence in the 1970s. These are starting to show up now in the marketplace. All the authentic vases made in this pattern will be Opalescent.Any unusual white or dark spots shown in the photos are from camera glare. This will make a great accessory item to any Victorian home. The item "Northwood Blue Opalescent Fluted Scrolls With Vine Footed Novelty Vase" is in sale since Sunday, December 31, 2017.
