I think this is Victorian, it looks like a yellow sea urchin with the lines within the glass, lots of wear to the base and a polished pontil, i think it might be a piece of Stourbridge glass as i have found 3 similar pieces where i live, one blue and one opaline all different shapes and sizes, although i have been blown away recently with the age wear base thing in my last two posts, the vase has a lot of staining to the inner bowl and it's 3 1/4 inches in height and 4 inches in width.
