I have two fire-engine-red RubyRush, medium and large. They are round with a little flattening at the poles. ¶ A small less-blushed spot on the back is orange over yellow, and the shallow calyx well is yellow green, around an open calyx. Faint but noticeable lenticel dots add visual interest. The stem is thin and shares some color from the blush. No ribbing to speak of.
