7.17 Ct. Blue Sapphire from Ceylon (Sri Lanka)

A rare and arresting find from Ceylon Sri Lanka, this GIA certified blue sapphire weighs 7.17 carats and presents in an elegant asscher octagon shape, dimensions 10.77 x 9.75 x 6.89 mm. Its intense, saturated blue commands attention, while an eye clean clarity at face up inspection ensures an open, vivid presentation without the need for concealment. Cut with an asscher pavilion and excellent polish, the facet architecture delivers a sophisticated play of light that balances depth with brilliance, producing the deep velvety flashes collectors prize. Heat treated to enhance stability and colour uniformity, this stone arrives with laboratory verification, making it a secure and rare acquisition for discerning connoisseurs. Offered exclusively by The Natural Sapphire Company, this sapphire is an invitation to join an elite group of owners who appreciate provenance, precision, and rarity.

Because of its exceptional size and clean, angular asscher octagon form, this sapphire is ideally suited to bespoke jewellery design, especially pieces that celebrate the stone as the hero element. At 7.17 carats and nearly 11 by 10 millimetres in footprint, it fills a ring bezel or prong setting with presence, while its depth of 6.89 mm retains excellent light return when set open faced, enabling designers to maximize the asscher facets for scintillation. The asscher octagon silhouette lends itself to both vintage inspired and contemporary executions, from architectural solitaire rings and three stone compositions to elevated halo and cathedral mountings that enhance its intense blue without overwhelming it. Its eye clean clarity allows for more open settings that showcase the stone directly to the viewer, while the excellent polish ensures every facet edge reads crisply under close inspection. Our design team at The Natural Sapphire Company will tailor metal choice, setting style, and proportion to your vision, ensuring the final piece is as singular as the gem itself. For clients seeking a statement of refined exclusivity, this Ceylon asscher octagon sapphire is a one of a kind foundation for a custom piece that will be cherished for generations.
