I’m submitting this piece for appraisal and possible authentication. It is a large, heavy, petal-shaped art glass/ceramic bowl or fairy lamp base, in a pink cased glass with white interior. The exterior has raised petal detailing and a frosted/satin finish that transitions from deep rose to pale pink. The interior is glossy white. There are no visible marks, but there is a rough pontil on the bottom. I believe it could be Victorian-era, possibly by Mt. Washington or another high-end American art glass maker. It appears hand-blown. I’ve only seen one similar piece online (listed for $400+), while others with smoother sides are much more common and lower in price. I’m hoping to confirm its origin, approximate age, rarity, and fair market value.

About 5 inches wide and 4 inches tall
