Late 1800s or very early 1900s antique brilliant cut glass decanter, not marked or signed that I could find. Measures about 6" in diameter x 7" tall. My photos don't do justice to this piece, though I tried to show its sparkle in the sunshine.
This came out of the estate of an American brilliant collector, and has been carefully cared for, unused for the last 80 years or so. No chips or cracks, pattern looks good without dulling or serious roughnesses. Glass is not clouded or scratched – this is a nice piece.
