1.81 Ct. Bluish Green Sapphire from Ceylon (Sri Lanka)

From the hills of Ceylon Sri Lanka to the careful hands of our master cutters, this 1.81 carat round bluish green sapphire carries a story that is both geological and artisanal. Born deep within the earth as corundum, its crystal lattice is a tightly packed arrangement of aluminum and oxygen that gives sapphires their remarkable strength and optical power. Tiny amounts of iron and titanium threaded through that lattice are responsible for the rare bluish green hue you see, a color that reads as ocean and forest at once. Mined in a land with centuries of gem lore, this stone was selected for its dark color intensity and transparent clarity, then gently heat treated to refine its tone and stability. Slightly included when evaluated at eye level, the stone retains natural markers of origin that collectors and connoisseurs prize, proof of an uncontrived life beneath the surface. The Natural Sapphire Company brings that provenance forward, preserving the gem story while preparing it for a lifetime of wear.

What transforms that geological heritage into an unmatched sparkle is the interplay between the sapphires intrinsic structure and the precision of its mixed brilliant cut. The 6.84 x 6.84 x 4.57 mm proportions were chosen to balance depth and table size, allowing light to enter, refract through the high index of the corundum lattice, and return as lively scintillation and subtle flashes of spectral dispersion. The mixed brilliant cut pairs a brilliant faceted crown with step or modified facets on the pavilion, creating a dialogue of bright white scintillation and deeper color windows. Excellent polish smooths each facet to a mirror finish, maximizing internal reflection and minimizing light leakage. Slight inclusions act like fingerprints of the stone, scattering light in complex ways that add character to the inner fire rather than diminishing it, especially when viewed in movement. The result is a darkly saturated bluish green that glows from within, a gem whose brilliance is not merely bright but layered, nuanced, and unmistakably alive. When set by The Natural Sapphire Company, this sapphire will move from a story of earth to a story of adornment, offering a visual presence that is both natural and exquisitely crafted.
