0.84 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.84 carat transparent oval blue sapphire embodies precise gemological balance between size, color, and optical performance, presented by The Natural Sapphire Company. The gem measures 6.83 x 5.11 x 2.95 mm, with proportions that yield an approximate depth of 49 percent relative to the average diameter, a dimensional relationship that supports both lively return of light and stable face up presence in a variety of settings. Color is described as medium intensity blue, showing lively saturation without oversaturation, and the stone is unenhanced, originating from Ceylon Sri Lanka, a source renowned for producing sapphires with clean, vibrant blue tones. Clarity at the eye level is graded very very slightly included, the inclusions are sufficiently minor to be inconsequential to the visual performance and structural integrity of the gem, and the excellent polish enhances facet crispness and overall visual clarity.

The geometric faceting is a mixed brilliant design engineered to maximize light play across the oval outline, combining a modified brilliant crown with a pavilion that favors controlled internal reflection. The crown features well proportioned star and kite facets that interlock with a series of precisely angled upper girdle facets, channeling incident light through the table and into the pavilion, while the pavilion employs a complementary arrangement of mains and lower facets that return light through mirror like symmetry. The oval outline is carefully oriented with the major axis aligned to the pavilion symmetry, minimizing light leakage along the long axis and promoting even scintillation across the face up view. Facet junctions are sharp and symmetry is tight, creating a geometric network that multiplies flashes of lighter and darker blue, enhancing both brilliance and contrast. The result is a controlled interplay between flashes of white light and saturated blue color, a balance achieved by judicious restraint of table size and calibrated pavilion angles which favor return rather than excessive dispersive leakage.

Craftsmanship extends beyond facet geometry to include rigorous attention to polish, girdle consistency, and axis alignment, all of which contribute materially to the gemmatic performance that collectors and connoisseurs expect from The Natural Sapphire Company. The excellent polish minimizes diffusion of light at facet borders, preserving crisp facet reflections, while the consistent girdle thickness facilitates secure mounting without compromising optical behavior. The lack of enhancement means the inherent crystal lattice and natural color zoning dictate the optical response, and the cutter has exploited those natural attributes rather than masking them, orienting the stone to maximize the most desirable, saturated directions of color. For practical jewelry considerations the stone’s dimensions and mixed brilliant faceting make it highly versatile, yielding strong face up color and dynamic scintillation in open settings, and a controlled, deep blue presence when set in low profile bezels that emphasize table reflections. For buyers who appreciate the technical aspects of cut geometry, this sapphire offers a textbook example of how precise facet planning and execution can extract maximum optical return from a natural Ceylon rough, delivering measurable brilliance, defined scintillation, and pure unenhanced color, all attested and offered by The Natural Sapphire Company.
