7.70 Ct. Blue Sapphire Crystal from Ceylon (Sri Lanka)

This exquisite, one of a kind blue sapphire is a rare discovery from the famed gem terraces of Ceylon Sri Lanka, a gem that carries both provenance and personality in equal measure. We present a single translucent 7.70 carat various shape sapphire, with exact dimensions of 13.62 x 10.59 x 8.95 mm, preserved in a rough crystal cut that celebrates the stone as it was coaxed from the earth. Evaluated at eye level, the clarity is slightly included, which lends the piece an honest, organic character while allowing light to move through the stone and reveal its inner life. The color intensity is medium, a serene blue that shifts subtly with changes in light, and the polish is excellent, a testament to careful finishing that retains the raw geometry of the crystal while maximizing surface luster. There has been no enhancement, so what you see is entirely natural, untreated, a direct narrative of geology and time. For connoisseurs seeking an authentic Ceylon example, this untreated sapphire is a rare offering, and it is available as a single, individual piece through The Natural Sapphire Company.

Where this sapphire truly distinguishes itself is in the way it responds to light, a response that is different from the more common gemstones you see every day. A diamond will scintillate, throwing sharp flashes across a wide spectrum because of its high refractive index, and many commercial sapphires will offer intense, uniform color due to heat treatment. This Ceylon sapphire does not compete on the same terms, it offers a gentler and more poetic brilliance. Its translucency creates an inner glow rather than a rain of pinpoint sparkles, and the rough crystal faceting scatters light in layered planes that reveal depth and movement as you change perspective. Slight inclusions at eye level act like fingerprints of formation, catching and diffusing light in ways that give the gem personality and a warmth that treated stones lack. Compared with aquamarine or blue topaz, which often present clear, uniform brightness, this sapphire offers complexity, a living color with flashes of lighter and deeper blue. Paired with a White Opal, the contrast is magnificent, the opal bringing a milky, iridescent field that sets off the sapphire s blue novelty, and the combination makes a composition that is both elegant and modern. In short, if brilliance is measured in character and rarity as much as in flash, this sapphire stands apart.

Owning this sapphire means claiming a piece of natural history that is unlikely to be replicated, an exclusive opportunity that we at The Natural Sapphire Company curate for discerning clients who appreciate the provenance and integrity of untreated gems. The rough crystal cut invites bespoke design, it encourages an artisan approach rather than a mass market setting, and our bench can work with you to imagine rings, pendants, or wearable art that respect the stone s shape and celebrate its unique geometry. Because it is untreated and slightly included, setting options can be chosen to protect the crystal form and to enhance the visual flow of light through the gem, preserving its translucency and excellent polish. For collectors, this stone represents the rarity of an untreated Ceylon sapphire at this size and form, and for someone commissioning a custom piece, it conveys the exclusivity of a singular gem that will not be replicated. We hold only one, and each commission receives direct consultation and careful design work, ensuring the final piece is as singular as the sapphire itself. If you wish to own a gem that speaks of provenance, craftsmanship, and an unaltered natural story, this 7.70 carat Ceylon sapphire, presented by The Natural Sapphire Company, is waiting to become the centerpiece of an heirloom or a bespoke creation that will be treasured for generations.
