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

This transparent 2.43 carat oval color change sapphire measures 8.29 by 6.46 by 4.76 millimeters, with a faceted mixed brilliant cut and an excellent polish that enhances light return and overall presentation. The stone displays a noteworthy color change, appearing deep teal green under fluorescent lighting and shifting toward a rich blue violet under incandescent illumination. Clarity is described as very slightly included, evaluated at eye level, which means the inclusions are minimal and do not detract from the gem's transparency or visual appeal. Color intensity is dark, contributing to a saturated, sophisticated tone that remains attractive at larger sizes. No enhancement has been applied to this sapphire, and its documented origin is Ceylon, Sri Lanka, a source known for producing high quality gem material.

The 2.43 carat weight is a defining attribute of this piece, both in terms of rarity and practical value. Sapphires exhibiting clear color change at weights above two carats are comparatively uncommon, and the incremental increase in carat weight produces a disproportionately larger presence when set in jewelry, making the stone read visually larger and more substantial. Weight also affects how the mixed brilliant cut interacts with light, improving depth of color and the dynamism of the color shift when handled or worn. The proportions, including a depth of 4.76 millimeters which represents approximately fifty seven percent of the length, are well balanced for mounting in a variety of settings from solitaire rings to bespoke pendants. As an unenhanced Ceylon sapphire with very slight eye visible inclusions and an excellent polish, this gem offers a combination of natural character and collector appeal. The Natural Sapphire Company documents these attributes to provide clarity on provenance, treatment status, and physical specifications for informed consideration.
