The object is a vintage Fenton blue opalescent hobnail vase, a highly recognizable piece of American art glass. The defining characteristic is its unique coloration, which transitions from a translucent, vivid blue in the body and base to a milky white opalescence along the top edge. The vase features the classic hobnail pattern, a textured surface covered in raised glass nubs designed to catch the light and add visual interest. Structurally, it is a footed, trumpet or cone-shaped vase, culminating in a decorative, double-crimped or ruffled rim that enhances its elegant appearance and makes it a sought-after collectible item
