Ruby – Lab-made, Faceted, Red, 672 ct
Like diamonds, rubies have industrial applications, so scientists have manufactured rubies in large quantities and sizes for research purposes. This 672-ct synthetic ruby was cut from a huge crystal originally grown in the 1970s for laser applications. Photo © Joel E. Arem, PhD, FGA. Used with permission.
