Here are the pretty Sierra or Pinwheel Pink Depression Glass Cups and Saucers by Jeannette. Sierra, or "Pinwheel," is known for its distinctive sawtooth edge on ribbed panels ending in the pinwheel design that resembles a circular saw blade. The saucers, like other pieces in this pattern, have the points around the outside edge, but the cups pointed ribs end about 1/4-inch down from the top so that the rim of the cup is smooth.
Each cup measures 2-1/8 inches tall and 3-1/2 inches in diameter across the top extending another 3/4-inch with the handle. The matching saucer is 5-1/2 inches in diameter.
Sierra was made by Jeannette Glass from 1931 to 1933. There is no mark.
Though the tiny points in this pattern were prone to breakage, there are no chips or cracks on any of these pieces. There are bubbles, a few rough mold seams, dimples, and the occasional straw mark. All of these manufacturing imperfections are common in Depression Glass. One saucer has two dimples in the cup ring. It also has a black ink-like fleck with a faint line running from it that I have not been able to remove.
