0.50 Ct. Alexandrite from Ceylon (Sri Lanka)

One beautiful transparent 0.50 carat pear shape green to purple alexandrite is presented with dimensions of 6.58 by 3.93 by 2.59 millimeters, mixed brilliant cut, very slightly included clarity evaluated at eye level, intense color intensity, and an excellent polish. The mixed brilliant faceting combines a brilliant crown with a faceted pavilion geometry that is calibrated to maximize both light return and the alexandrite color change phenomenon. The cutter oriented the pavilion and crown facet junctions to enhance the dichroic response, preserving strong green hue under daylight related spectra and a rich purple to purplish red in incandescent or warm spectrum lighting. The gem is natural, with no enhancement, and is of Ceylon Sri Lanka origin, a provenance that is known for fine alexandrite specimens with lively tone and clean crystal structure, attributes that are evident here in the even facet junctions and controlled facet angles. The excellent polish yields crisp facet reflections and minimal surface disturbance, allowing observers to assess the internal clarity and color zones with minimal distraction, while the very slightly included clarity at eye level indicates only minor inclusions that do not interrupt the overall visual appeal or the optical performance of the stone.

From a rarity perspective this 0.50 carat pear shaped alexandrite is exceptional in both size and color when compared to typical offerings in the market. Alexandrite specimens showing pronounced color change with intense saturation are uncommon above half a carat, and pear shapes with precise mixed brilliant cutting that preserve strong color change across viewing conditions are rarer still. Collectors and connoisseurs will note the balance between weight, dimensions, and optical performance, a balance achieved through meticulous proportioning that maintains optimal crown height and pavilion depth to favor both dispersion and color shift. The combination of transparent body, intense color intensity, and untreated origin elevates its desirability for high end jewelry applications, particularly rings and pendants where the pear outline and pointed termination will emphasize the shift between green and purple as lighting changes. This alexandrite is offered through The Natural Gemstone Company, and it represents a carefully selected example of Ceylon material that will appeal to buyers seeking technical excellence, natural provenance, and a rare instance of significant color change in a well proportioned half carat size.
