Ruby is corundum's rarest expression — the same mineral as sapphire, yet transformed by chromium into a stone of such commanding presence that it has historically commanded higher per-carat prices than any other gem on earth.
This 8.12 carats Star Ruby of Purplish Red moderately strong hue from Vietnam was selected for the Skyjems Archive not as an afterthought, but as a deliberate acquisition. Unheated rubies of genuine pigeon-blood saturation are among the rarest objects on the planet. Acquire it with the understanding that stones of this caliber rarely circulate outside private collections.
