Among the five cardinal gemstones, the ruby holds a special place. This striking gem fuses shades of red and blue into new menageries of color. Like other gemstones, rubies are imprints of past geological processes, shedding light on the tectonic forces churning below our feet.

This specimen is a piece of rough ruby, demonstrating its natural form. First appearing in the Fifth Edition, this gemstone comes with a small informational card that serves as certificate of authenticity.
