A dreamy, velvety violet-blue cushion-cut sapphire, weighing 5.36 carats, and accompanied by an AGL certificate stating, ‘no heat or clarity enhancement, Ceylon origin’, glistens and glows from within a halo of rose-cut diamonds, set in silver atop an 18K yellow gold gallery and ring shank. Fanciful rose-cut diamond ornaments adorn the shoulders of this truly enchanting and exotic mid-nineteenth century jewel. *Although unmentioned in the certificate (and unphotographable), the gemstone definitely displays distinct color-change properties (blue and violet) depending on the light source.
