Reflecting the vibrancy and delicacy of one of nature's loveliest birds, Quezal glass of the early 20th century remains a popular collectible a century later. With its lush, organic shapes and naturalistic themes, Quezal art glass perfectly epitomizes the Art Nouveau era. These well-loved glass pieces have an iridescent quality unmatched by contemporary work. Popular forms used in Quezal art glass include floral and leaf patterns, as well as feathers. Inlaid threads within the glass come in a variety of shades and manage to mimic the veined surface of real leaves and flowers. Common colors to find include opalescent greens and golds, with red being the most rare shade in the Quezal catalog. The company also produces a number of light fixtures, making a Quezal shade a popular collectible, as well. These pieces, like Quezal vases and compotes, often take the form of a flower such as a crocus or a lily of the valley.
