This vase was produced by Duncan Miller Glass Company, a prominent American glassmaker active from 1893 to 1955 in Washington, Pennsylvania. The company was renowned for its high-quality pressed and blown glass, and pieces featuring sterling silver overlay were among their most elegant offerings from the early to mid-20th century. The black glass, often called 'ebony' or 'black amethyst,' was particularly popular during the Art Deco period of the 1920s-1930s.

Duncan Miller pieces with sterling overlay are highly sought after by collectors of American art glass and Depression-era glassware. The combination of lustrous black glass with ornate silver decoration appeals to enthusiasts of Art Deco design, vintage glassware collectors, and those who appreciate the craftsmanship of early 20th-century American decorative arts. These pieces represent a pinnacle of American glass production and are valued for their aesthetic beauty, historical significance, and the skill required to create the intricate silver overlay patterns.

Please note the loss of some silver details along the rim.
