0.94 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This oval blue sapphire weighs 0.94 carat, and measures 6.50 by 4.90 by 3.66 millimeters, with a calculated depth of 64.2 percent, dimensions that are balanced for setting in rings or pendant designs, and for optical performance in everyday wear. The cutting style is a mixed brilliant, which combines a brilliant facet arrangement on the crown with a more structured pavilion geometry, creating an interaction between lively scintillation and controlled light return. The pavilion and crown proportions have been executed to retain strong internal reflection, while the table and crown facets are sized to present vivid zone contrast without excessive windowing, and the excellent polish produces crisp facet junctions and bright facet faces. The oval outline has been shaped to maintain symmetry across the axes, and the girdle appears well centered relative to the table and culet, contributing to even light distribution across the face up view.

Color is medium intense, an appealing balance between tone and saturation that reads as a clear blue with slightly cool leaning when examined under neutral lighting, an appearance consistent with fine sapphires from Ceylon Sri Lanka, the recorded origin for this stone. The hue exhibits purity with only minor modifiers, and the medium intense classification supports strong color presence in most mounting choices without appearing overly dark in low light. Clarity is described as very very slightly included when evaluated at eye level, meaning inclusions are minimal and do not interrupt the visual flow of color or sparkle, allowing the mixed brilliant faceting to produce lively scintillation and crisp contrast. Optical characteristics of corundum enhance the visual performance, with a refractive index in the typical sapphire range of about 1.76 to 1.77, low birefringence that preserves color integrity across viewing angles, and a specific gravity near 4.00 that gives the gem a substantial feel relative to its size.

This sapphire is untreated, with no enhancement recorded, a factor that directly influences long term stability and value, because its color and clarity result from natural formation rather than artificial diffusion or fracture filling. As a natural, unenhanced Ceylon sapphire, the stone retains inherent thermal and chemical stability that will preserve its color over decades under normal conditions, and the corundum hardness of 9 on the Mohs scale makes it highly resistant to abrasion, maintaining facet crispness and polish through regular use. The excellent polish and durable facet edges will help the gem retain its luster, and because there are no surface treatments to degrade, routine care consisting of gentle cleaning and periodic professional inspection will keep the sapphire performing optically and cosmetically for generations.

At The Natural Sapphire Company we present this 0.94 carat Ceylon oval as a precision cut, natural example that will continue to captivate through its balanced proportions, stable medium intense color, and superior polish. For settings, consider mounts that allow light to enter through the pavilion for maximum color return, such as open basket or low profile prong styles, and metal choices that complement the cool blue, typically platinum or white gold to emphasize crispness, or yellow gold to add warmth to the tone. Because of its mixed brilliant faceting and excellent surface finish, the stone will display dynamic scintillation in movement, while remaining legible and elegant in stationary viewing. Our gemological team is available to discuss setting options and to provide additional documentation, ensuring that the technical characteristics and provenance of this untreated Ceylon sapphire are fully represented for discerning buyers who prioritize precision and enduring natural beauty.
