1.34 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.34 carat round blue sapphire presents precise gemological proportions and a clarity and color profile that will satisfy discerning buyers, The Natural Sapphire Company offers this transparent example which measures 6.58 by 6.49 by 3.92 mm, the slightly non circular diameters indicate careful faceting to preserve weight while maintaining optical performance, the measured depth of approximately 3.92 mm yields a depth ratio near 60 percent which optimizes contrast and return for this mixed brilliant architecture. The stone is cut in a mixed brilliant style, combining a brilliant faceted crown with a modified step pavilion, this configuration emphasizes scintillation on the crown plane and controlled light leakage from pavilion facets, the result is a lively balance between flash and body color. Clarity is graded as very very slightly included evaluated at eye level, the inclusions are minimal and do not interrupt the visual field under normal viewing conditions, the polish is graded excellent which enhances facet definition and maximizes specular reflection. The color exhibits vivid intensity, a saturated primary blue that retains depth without approaching overly dark tone, and the stone is natural with no enhancement, origin is Ceylon Sri Lanka, and this combination of natural origin, lack of enhancement, and clean eye level appearance makes this gem rare in the market segment it occupies.

From a faceting and craftsmanship perspective this mixed brilliant cut has been executed to emphasize symmetry and optical table size, crown facet array has been proportioned to create multiple small flashes for lively scintillation, crown angles have been set to interact with the pavilion plane in a way that disperses light into both pinpoint highlights and broad color flashes. The pavilion has been modified in a step like fashion to deepen body color without producing excessive windowing, the pavilion facet junctions and girdle meet with consistent symmetry which preserves alignment between crown and pavilion facet sets, each facet junction contributes to consistent light pathing which yields stable face up color and predictable movement as the stone is tilted. Excellent polish reduces surface diffusion and preserves the integrity of the facet junctions, this directly increases contrast between facets and improves apparent clarity, the mixed brilliant style here was chosen deliberately to balance the need for saturated Ceylon blue with the desire for lively sparkle, the outcome is a gem that reads as vivid and alive in static observation and accelerates to brilliant in motion.

Color behavior and optical character deserve focused attention for buyers who evaluate sapphires technically, the face up hue is a rich medium to medium deep blue with vivid saturation, the tone sits in a range that conveys presence on the finger while avoiding the heavy absorption that can mute brilliance. Because the sapphire is transparent with minimal inclusions, light transmits into the body and interacts with internal facet geometry to produce both strong body color and pronounced brilliance. The stone displays consistent color across the table and crown, which indicates minimal zoning and a homogenized crystal growth pattern, this uniformity is particularly valuable for bezel and halo settings because it prevents perceived spotty or uneven color under close viewing. No heat or other modifications have been applied, therefore the color and internal character are entirely natural, buyers seeking provenance and integrity will value that attribute. In different lighting environments the gem shifts subtly from a bright vivid blue under daylight or cool LED to a deeper saturated blue under incandescent sources, this predictable pleochroic behavior is characteristic of corundum and contributes to the gem feeling dynamic across contexts.

Practical considerations for use and setting emphasize the sapphires versatility, with a diameter near 6.5 mm and a 1.34 carat weight the stone is well suited to center stone applications in engagement rings, for pendants or dress rings, and for coordinating matched pairs in high quality earring designs. The moderate depth of approximately 60 percent allows for relatively low profile settings, yet the modified pavilion preserves depth of color so that a shallow bezel will not materially diminish the richness. For daily wear we recommend a protective four or six prong setting with secure head design, or a bezel where maximal protection is required, the excellent polish and clean eye level clarity make this sapphire an excellent candidate for a solitaire design because the faceting pattern will deliver both focused brilliance and enduring color presence. The Natural Sapphire Company can assist with bespoke mounting options, and a gem of Ceylon origin and no enhancement is an excellent foundation for a precision setting that will perform across casual and formal contexts, the sapphire will read equally at ease with refined evening wear and with understated daytime pieces, and its balanced proportions and technical quality make it a reliable choice for customers who prioritize craftsmanship, origin, and natural integrity.
