2.10 Ct. Alexandrite from Ceylon (Sri Lanka)

This Other certified Color change alexandrite is a transparent, finely faceted specimen weighing 2.10 carat, presented in an elegant oval outline measuring 10.00 by 6.62 by 4.02 mm, with a length to width ratio of 1.51, proportions that favor both classical and contemporary mounting styles. The gem has been fashioned in a mixed brilliant cut, combining a brilliant crown with a carefully calibrated step pavilion, a combination that yields both strong scintillation and controlled light leakage to enhance the color changing phenomenon. Clarity is graded as very slightly included, evaluated at eye level, indicating only minimal internal features that do not detract from overall visual appeal when mounted. Color intensity is described as medium, offering a pleasing balance between saturation and versatility, and the polish has been executed to an excellent standard, resulting in crisp facet junctions and high surface luster. No enhancements have been applied to this piece, and its origin is Ceylon Sri Lanka, a provenance known for producing alexandrites with clear transparency and distinctive color response. The Natural Gemstone Company presents this stone with full attention to its natural state and cutting integrity.

The color change itself is the defining technical attribute of this alexandrite, shifting from a greenish hue in daylight or cool light sources to a reddish tone under incandescent or warm lighting conditions, a transformation stemming from trace chromium and the complex interplay of selective absorption bands with the spectral qualities of viewing light. The mixed brilliant faceting strategy was chosen to maximize both the spectral shift and overall brilliance, by using a broad table and proportioned crown facets to permit even distribution of daylight, while the step pavilion facets create directional flashes that concentrate warm wavelength return under incandescent illumination. Medium color intensity ensures the green and red endpoints are both perceptible without becoming oversaturated, which is particularly valuable for jewelry where environment and mounting will influence perceived tone. The very slightly included clarity grading means that inclusions are small and isolated, often located away from the table or confined to facet junctions, allowing the gem to present a clean face up appearance that supports strong pleochroic display and stable light performance. Excellent polish and tight symmetry reflect precise lapidary control, minimizing light scatter and enhancing the gemological attributes that collectors and connoisseurs evaluate, such as facet crispness, table reflectivity, and pavilion angle consistency.

From a practical and stylistic standpoint this 2.10 carat oval alexandrite combines durability with design flexibility, as chrysoberyl based alexandrite ranks approximately 8.5 on the Mohs scale, a hardness that facilitates regular wear without compromising facet integrity. The oval outline and the 10.00 by 6.62 by 4.02 mm dimensions are ideally suited to a variety of settings, including solitaire rings that showcase the color change, halo designs that amplify apparent size and sparkle, bezel settings that protect the girdle for everyday wear, and pendants or single stone earrings where the dynamic color will read attractively in motion. The unenhanced nature of the stone supports a wide range of design intentions, from minimally set pieces that highlight natural character to more elaborate constructions that employ contrasting metals or accent diamonds to modulate perceived hue and contrast. Whether paired with day to day attire for a refined but relaxed look, or reserved for formal settings where its color shift can become a focal point under varied lighting, this alexandrite offers a rare combination of gemological integrity and stylistic adaptability. For clients seeking a natural, well cut, and transparently documented alexandrite, The Natural Gemstone Company is prepared to provide additional details on certification, photographic documentation under multiple light sources, and bespoke mounting advice to optimize both appearance and durability.
