Here is a very large, stunning natural and untreated oval Star Ruby from India. The stone is 18.5 X 15.25 mm, weighs 20.67 carats, and is a well cut cabochon. Its color is a bright deep raspberry red - not at all overly dark or purple - with a crisp, clear and strong star, as shown; although it is not perfectly centered when viewed from some angles.
