2.21 Ct. Alexandrite from Ceylon (Sri Lanka)

This listing describes a natural cushion cut alexandrite weighing 2.21 carats, with dimensions 8.92 by 7.44 by 3.67 millimeters. The stone is faceted in a mixed brilliant style to balance scintillation and color depth, and presents a medium color intensity with a pronounced color change from greenish tones in fluorescent or daylight conditions to orangish hues under incandescent light. Clarity is graded as eye clean at typical viewing distance, and the polish is excellent. The specimen is natural, untreated, and shows no enhancement, originating from Ceylon, Sri Lanka. Alexandrite is a variety of chrysoberyl with a Mohs hardness of approximately 8.5, providing good resistance to everyday wear, and the mixed brilliant cut optimizes both its internal fire and its distinctive daylight to incandescent color shift.

Compared to lab-grown alexandrite, this natural Ceylon gem offers distinct practical and qualitative differences. The color change in natural stones is the result of specific trace element chemistry and growth conditions within the host crystal, producing subtle variations in hue, saturation, and transition under different light sources that are inherently variable and individual to each stone. Natural stones commonly bear growth features and internal characteristics that serve as reliable indicators of provenance and formation, and this particular gem is documented as unenhanced and sourced from Sri Lanka, which supports accurate identification and long-term valuation. Lab-grown counterparts can exhibit very consistent color and clarity at a lower price point, and they are valuable for certain applications, but they lack the geological history, natural growth signatures, and rarity that collectors and traditional connoisseurs prioritize. As supplied by The Natural Gemstone Company, this alexandrite is presented with transparent disclosure of origin and treatment status, making it suitable for customers who require an authentic, untreated natural gem with the optical complexity and provenance that distinguish natural alexandrite from synthetic material.
