1.46 Ct. Orangish Yellow Sapphire from Ceylon (Sri Lanka)

This 1.46 carat oval orangish yellow sapphire presents a compelling combination of measured proportions and refined cutting, offering both immediate visual appeal and technical excellence. The stone measures 8.00 x 6.17 x 3.53 mm, producing a length to width ratio of approximately one point three, a proportion that reads as elegant on finger and ensures balanced dispersion of light across the face up view. The pavilion depth of three point five three millimeters yields a depth percentage of approximately forty nine point eight percent when referenced to the average of the length and width, resulting in a strong face up spread and lively scintillation while maintaining excellent transparency. Cut as a mixed brilliant, the crown is oriented to deliver vivid crown brilliance with precisely placed star and bezel facets, while the pavilion is calibrated with modified brilliant faceting to reinforce return of light and to emphasize the saturated orangish yellow tone. Polish is graded excellent, with crisp facet junctions and mirror smooth facet planes that enhance gemological performance without introducing surface diffusion or hazing.

Color is the defining character of this sapphire, described as orangish yellow with intense color intensity, and exhibiting even distribution across the table with no significant color zoning when viewed face up. The hue occupies the intersection of warm orange and vivid yellow, a profile that reads as luminous and lively under both natural daylight and controlled artificial lighting, and that maintains strong saturation without veering to brownish overtones. The stone has undergone beryllium diffusion enhancement, a reactive diffusion process that introduces small amounts of beryllium into the lattice to stabilize and intensify warm tones, and that is considered permanent to the stone. This treatment is fully disclosed, and while it affects valuation relative to untreated material, beryllium diffusion has become an accepted and consistent method for producing reliably saturated fancy tones when applied by skilled lapidaries. Origin on the report is Ceylon Sri Lanka, a region with a long history of producing sapphires with lively hues and transparent bodycolor, and the documented origin adds provenance that attracts collectors who focus on geographic sourcing as part of their acquisition criteria.

Clarity is graded very slightly included as evaluated at eye level, and the internal characteristics are minor and localized, consisting of fine silk and minute pinpoint crystals that do not interfere with transparency or with the gemological performance of the mixed brilliant faceting. The excellent polish and the well calibrated facet angles minimize any visual impact of these inclusions in face up presentation, supporting a clean and luminous table scintillation. From a lapidary perspective, the cutter prioritized optimal light return and face up color rather than maximizing apparent weight, producing a stone that reads larger than its carat weight might suggest when set. The crisp facet junctions and uniformity of angles across the crown and pavilion reflect high level craftsmanship, and symmetry is executed to maintain consistent bar and pinpoint scintillation across the oval outline. For jewelry design considerations, the stone performs exceptionally well in ring centers and pendant heads where the shallow to medium depth accentuates brightness and color spread, and for protective mounting we recommend a four to six prong design or low bezel that preserves the face up presentation while offering secure seating.

From an investment perspective the sapphire occupies a nuanced and realistic position in the colored stone market, combining collectible color, documented origin, and durable enhancement. Beryllium diffused stones trade on different market fundamentals than untreated sapphires, generally at lower per carat premiums, yet they also present a favorable risk to reward profile for buyers seeking intense fancy tones with consistent availability and predictable performance. The rarity of well cut, transparent, and intensely colored orangish yellow sapphires with Ceylon provenance supports long term demand from connoisseurs and from designers seeking distinctive center stones. Supply constraints for high clarity material of this particular hue, together with growing consumer interest in warm fancy colors, create a structural backdrop for appreciation over time, provided that the owner retains documentation and provenance. In today s market certification and transparent disclosure are critical to value retention, and The Natural Sapphire Company provides comprehensive reporting and provenance information to maximize resale potential and collector confidence. For buyers who prioritize technical excellence, measured proportions, and an attractive face up spread combined with a lively orangish yellow saturation, this 1.46 carat mixed brilliant oval offers both immediate aesthetic gratification and a realistic pathway to future appreciation when held as part of a curated colored gemstone portfolio.
