0.89 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional transparent 0.89 carat oval blue sapphire measures 5.55 by 4.89 by 4.15 mm, and it is presented in a mixed brilliant faceted cutting style. The gem displays a vivid color intensity that reads as a deep, saturated blue when viewed face up, and the proportions of the cut maximize scintillation while preserving color depth. The clarity grade has been evaluated as slightly included at eye level, and the polish is excellent, providing crisp facet junctions and lively reflections. This stone is unenhanced, with no heat or diffusion treatment, and it is from Ceylon Sri Lanka, a classic origin known for producing lively and richly colored blue sapphires. At The Natural Sapphire Company we prioritize accurate, transparent descriptions, and these objective measurements and grades are intended to help an educated buyer assess the gem in terms of cut, clarity, color, and provenance.

The signature that makes this sapphire unmistakable lies in its natural inclusions, and these inclusions are both diagnostic and beautiful. Under magnification the stone reveals fine, needlelike rutile silk that is oriented in multiple directions, creating a soft, velvety scattering of light that subtly mutes some highlights and enhances the stone against direct light. In addition to silk, there are small, acute crystal inclusions and minute negative crystals that act as pinpoints of contrast, producing tiny reflective flashes when table facets catch them. There are also a few healed fissures and fingerprint style two phase inclusions, which are common in natural sapphires from Ceylon, and these features demonstrate internal growth and natural healing processes rather than indicators of treatment. Together these inclusion types create a distinctive internal fingerprint for this sapphire, a pattern of silk, crystals, and healing that experienced gemologists use as part of origin assessment and that collectors prize as evidence of an unheated natural gem.

From the perspective of value and market desirability, several factors make this 0.89 carat Ceylon sapphire attractive to an informed buyer. The vivid color intensity is the primary driver of value, as saturation and tone determine the visual impact and rarity of blue sapphires in the trade. The mixed brilliant cut was chosen to balance color and brilliance, so face up the gem presents an even, saturated blue while still returning lively sparkle. The clarity description of slightly included at eye level means that under normal viewing conditions the inclusions do not dominate the visual experience, and when set they will be even less apparent. The absence of any enhancement is highly significant, because unheated Ceylon sapphires command a premium due to their natural color stability and rarity. The excellent polish further boosts light return and lapidary symmetry, which collectors and appraisers consider when assigning market value. For those requiring independent verification, the inclusion suites described here are consistent with natural origin indicators used by gemological laboratories, and they help to form the gemological story of the stone.

Practical considerations for design and care are straightforward for a gem of this size and quality. The oval 5.55 by 4.89 by 4.15 mm proportions are ideal for classic solitaire rings, three stone settings, or refined pendant mounts, and the mixed brilliant faceting will perform well in both open and bezel styles, though open settings optimize light entry and display. Because the gem is natural and unenhanced, routine care should include avoiding sudden temperature extremes and hard knocks, storing separately to prevent abrasion, and cleaning with warm soapy water and a soft brush. For clients who prioritize documentation, The Natural Sapphire Company can provide detailed provenance notes and facilitate independent laboratory reports if required. If you are considering this sapphire for a bespoke commission or to pair with diamonds or other colored gems, our team can advise on setting styles that emphasize the vivid color and showcase the unique inclusions that give this stone its unmistakable signature.
