2.43 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 2.43 carat oval blue sapphire from Ceylon, presented by The Natural Sapphire Company, exhibits a transparent body with precise dimensions of 9.07 by 6.91 by 4.48 millimeters, offering a balanced oval outline well suited for fine jewelry settings. The cutting style is faceted with a mixed brilliant configuration, combining a faceted crown optimized for dispersion with a pavilion that employs brilliant style facets for strong light return. Color intensity is classified as light, producing a soft Ceylon blue that displays appealing tone against white metals and a refined presence when set alone. Clarity has been assessed as very slightly included, evaluated at eye level, and the gem has received conventional heat treatment to enhance color saturation and overall visual harmony.

From a cutting and proportion perspective, the mixed brilliant strategy in this stone was chosen to maximize scintillation while preserving the delicate light blue color characteristic of Sri Lankan sapphires. The total depth measures approximately four point four eight millimeters, producing an overall depth of about fifty six percent relative to the average diameter, a proportion range that supports both stable faceting geometry and efficient light return. The crown has been faceted to produce controlled flash and table brilliance, while the pavilion arrangement switches to brilliant facets to convert off axis light into dispersed flashes. The result is a lively but refined play of light, with excellent polish that yields crisp facet junctions and minimal surface disturbances. Girdle thickness has been moderated to allow secure mounting without compromising visual weight.

Internal characteristics serve as natural fingerprints that make this sapphire both identifiable and unique, and the inclusions in this specimen add sympathetic character rather than detract from beauty. Under magnification the stone presents discrete mineral crystals and fine needle like inclusions which are typical of corundum from Ceylon, and there are localized healed feathers and minute crystal clusters that produce subtle clouding in isolated facet windows. Because the clarity was assessed at eye level as very slightly included, these features are not prominent to unaided viewing but provide diagnostic patterns for gemologists and laboratories. Heat treatment has partially altered some inclusion boundaries through thermal healing, which can change the appearance of tiny internal fractures and cause rounding of crystal edges, and this is an expected and stable outcome of standard heat enhancement practices.

For design and setting considerations this oval sapphire’s dimensions and weight translate to a versatile center stone that sits well in both solitaire rings and halo or three stone configurations, offering a classical profile that lends itself to bezel and prong styles. The light blue tone pairs particularly well with platinum and white gold for a cool palette, and with yellow gold when a warmer contrast is desired, thanks to the stone’s moderate saturation and transparent body. The Natural Sapphire Company discloses the stone’s heat treatment and Ceylon origin, and we can facilitate independent gemological documentation and mapping of the inclusion pattern to support provenance and future identification. This sapphire demonstrates meticulous cutting, excellent polish, and natural inclusion features that together create a gemstone with technical integrity and enduring character.
