The De Young Red diamond is a 5.03-carat, brilliant cut red diamond. The main kite-shaped facets on the crown are divided in two, giving the stone more brilliance than a standard round brilliant cut. The stone is not pure red but has a slight brown hue, which makes it appear like a fine red garnet and indeed, it was once purchased as such at an estate sale.
It is the third largest red diamond in the world, after the Moussaieff Red (5.11 carats) and the Red Diamond (5.05 carats). The De Young Red is currently exhibited at the Smithsonian Museum in Washington D.C
