1.23 Ct. Color Change Sapphire from Ceylon (Sri Lanka)

This sapphire is a 1.23 carat, oval shape, transparent color change stone, presented with precise measurements of 7.28 millimeters by 5.72 millimeters by 3.58 millimeters, and a mixed brilliant cut. The combination of weight and proportions yields a gemstone that balances presence with wearability, suitable for a variety of fine jewelry applications. Color behavior is a defining characteristic, with the stone exhibiting a distinct shift between lighting environments, appearing a medium to strong blue under cooler light sources, and moving toward a bluish violet under warmer, incandescent illumination. Clarity is graded as very very slightly included, evaluated at eye level, indicating minimal inclusions that do not materially affect the visual transparency or brilliance of the stone. The polish is graded excellent, ensuring that facet junctions are clean and reflective, and that the mixed brilliant cutting scheme optimizes light return across the oval outline.

From a gemological perspective, this sapphire demonstrates attributes sought after by connoisseurs and lapidaries alike. The mixed brilliant cut combines a faceted pavilion designed for optimal scintillation, with a crown arrangement that distributes color evenly across the table, which is particularly effective in a color change material where the interplay of light and absorption is central to the gem experience. The medium intense color intensity provides a strong, saturated appearance without appearing overly dark, allowing facets to display a lively play of light. With transparency described as transparent, light passes through the stone with minimal obstruction, enhancing both brilliance and the perceptible color shift. The very very slightly included clarity grade, assessed at eye level, reflects inclusions that are small and localized, and these serve to affirm natural origin rather than to detract from the overall visual quality.

The provenance of this gemstone is Ceylon, Sri Lanka, a region with a storied history in sapphire production that stretches back centuries, and that has long been esteemed for producing corundum with fine color and clarity. Traditionally, sapphires from Sri Lanka were reserved for royal regalia, religious ornamentation, and talismanic objects, valued both for their beauty and for the cultural associations of protection, wisdom, and status that have accompanied blue corundum in many societies. Color change sapphires have historically been prized for their rarity and perceived mystique, as the ability of a single gem to present distinct hues under different lights elevated its use in ceremonial and high status jewelry. The present stone, with its Sri Lankan origin and natural color change character, sits within that lineage, reflecting both the geological conditions that produce exceptional corundum in the Ceylon mines, and the longer human tradition of valuing such stones for personal and symbolic adornment.

Practical considerations for this gem are straightforward and reassuring, beginning with the fact that there has been no enhancement, the stone is natural and untreated, and therefore presents an unaltered example of Ceylon sapphire material. The combination of an excellent polish and a balanced mixed brilliant cut makes the stone well suited to secure bezel or prong settings where the color change effect may be appreciated in daily wear, while the dimensions and weight provide an attractive profile for rings, pendants, and bespoke pieces. Care for the sapphire is consistent with standard practices for corundum, avoiding extreme thermal shock and harsh chemicals, and routine cleaning with mild detergent and a soft brush will maintain its appearance. The Natural Sapphire Company can provide full provenance information and gemological documentation upon request, supporting the stone with accurate descriptive data for appraisal or bespoke design work. This gem represents a measured example of Ceylon color change sapphire, combining documented origin, natural, untreated character, and the optical complexity that has tied such gems to traditional uses and enduring appreciation.
