This transparent 1.13 carat asscher octagon blue sapphire presents precise proportions and meticulous execution, dimensions 6.16 x 6.02 x 3.45 mm, depth percentage approximately 56.6 percent, and an asscher cut that emphasizes step facets and truncated corners to form the octagonal outline. The stone is classified as eye clean at standard eye level inspection, exhibiting no inclusions visible to the unaided eye, which preserves the step cut geometry and allows uninterrupted light travel across the facet planes. Color is described as blue with medium intensity, demonstrating balanced saturation and tone that reads consistently across the table and crown, and the excellent polish ensures crisp facet junctions and smooth facet planes that enhance the stone s face up vibrancy. Enhancement is heat treated, a stable and industry accepted process for natural sapphires, and origin is Ceylon Sri Lanka, a source historically prized for fine blue material. The Natural Sapphire Company discloses treatment and origin fully, reflecting a commitment to transparent technical information.
The asscher cut is a step cut by definition, with concentric square or rectangular steps on both crown and pavilion producing a hall of mirrors effect when executed with precision, and this sapphire shows tight symmetry and well aligned steps that contribute to controlled light return and a refined scintillation pattern. The truncated corners produce the octagon shape, reducing chipping risk at corners compared to a sharp square outline, and the relatively deep pavilion to table ratio in this example supports face up color concentration without excessive windowing. Facet geometry is optimized to trade maximum color saturation with lively edge reflections rather than the small brilliant style flashes, and the cutter has prioritized proportionality of table to crown height in order to maintain a uniform field of color across the table. The excellent polish is evident at facet junctions and along the girdle, where a clean finish reduces surface diffusion and maximizes optical contrast between steps, allowing a knowledgeable buyer to assess the sapphire s craftsmanship readily.
Ethical sourcing and traceability are integral to the provenance of this gem, the sapphire originates from Ceylon Sri Lanka and has been supplied through traceable channels vetted for responsible practices, The Natural Sapphire Company maintains documented chain of custody from mine to market, and works with partners who adhere to environmental standards and fair labor practices. Where material is sourced from small scale or artisanal operations, our procurement emphasizes direct relationships that ensure fair remuneration to miners and reinvestment into local communities, and we require transparent disclosure of treatments and origin at the point of sale. Heat treatment disclosure is part of our standard documentation, and the way the material is cut and finished is recorded so a collector can evaluate both the technical attributes and the social impact of the stone s journey. This level of provenance supports a conscious consumer s desire to build a collection that pairs technical excellence with ethical accountability.
For a discerning collector or a conscious consumer seeking a durable and versatile center stone, this 1.13 carat asscher octagon blue sapphire is well suited to multiple settings, corundum hardness nine affords daily wearability while the truncated corners suggest settings that provide corner protection such as bezel or secure four prong designs with reinforced mounts. The moderate size and balanced depth make it appealing as an engagement center or as a focal pendant, and the step cut geometry complements modern vintage or architectural design languages in jewelry, where clean lines and facet discipline are prized. To align with ethical purchasing values, pairing this sapphire with recycled gold or certified conflict free platinum, and with accent stones sourced under equivalent ethical standards, creates a coherent conscious collection piece. Documentation of origin and treatment is available through The Natural Sapphire Company to support appraisal and resale valuation, and for buyers who prioritize technical specifications and verified provenance, this sapphire offers a precise blend of cut, clarity, color, craftsmanship, and responsible sourcing.
