Product description

If you are searching for a singular stone that resolves the quest for a meaningful engagement piece or a standout collector specimen, this sapphire answers that search with authority. Many clients come to us wanting something that feels both timeless and truly one of a kind, something that will become the focal point of a design or the crown jewel of a collection, and this gem is precisely the solution. Offered by The Natural Sapphire Company, this semi transparent bi color sapphire weighs 18.89 carat, large enough to make a statement while retaining an intimate, natural presence. Its varied shape and rough crystal cut give it an organic silhouette that speaks to clients who prefer authenticity over perfection, and its natural, unenhanced state ensures that the hues and internal character you see are the genuine signature of Ceylon, Sri Lanka, rather than the result of treatment.

Let me describe the stone in detail so you can imagine how it will sit in your hands and in your setting. The dimensions are 31.25 by 10.15 by 7.17 mm, a length that gives real presence on a finger or pendant, and an elegant thickness that accepts bezel or prong work without overpowering the mounting. The cut preserves the raw crystal form, with facets and planes that catch light in a soft, natural way, rather than the mirror sparkle of a faceted, commercial cut. Its clarity grade is very slightly included evaluated at eye level, which means the gem reads clean to most viewers while retaining small, characteristic inclusions that tell the story of its formation. These tiny features do not diminish the gem, they enrich it, offering a textured, almost painterly aspect to the bi color transition. The color intensity is medium, a sweet balance that allows both tones in the bi color to be appreciated without either dominating, and the polish is excellent, enhancing surface luster and tactile appeal. Crucially for discerning buyers, enhancement is none, and the origin is Ceylon, Sri Lanka, a provenance celebrated for producing sapphires with lively personality and historical depth.

For a customer who needs reassurance that their search ends with a genuine and evocative stone, this sapphire is the ideal solution. Its combination of substantial weight, distinctive bi color character, and natural unenhanced state meets the desires of those who want authenticity, and its rough crystal cut opens creative possibilities for bespoke settings that highlight the stone rather than mask it. At The Natural Sapphire Company we guide clients through options for custom design, whether you imagine a minimalist bezel that emphasizes form, an artisan setting that embraces the stone as a sculptural element, or a classic halo that brings an elegant contrast. We can provide measured photographs, setting mockups, and expert advice on metal choice to complement the medium color intensity and the bi color nature of the gem. If your aim is to conclude a long search with a piece that feels resolved and right, this sapphire will bring that sense of closure, because it carries both the rarity collectors prize and the intimate narrative that transforms a gemstone into a treasured object. Please contact our team for further details, to discuss bespoke settings, or to arrange a private viewing, and allow us to help you secure this remarkable Ceylon sapphire as the final chapter in your search.
