1.03 Ct. Alexandrite from Ceylon (Sri Lanka)

One beautiful transparent 1.03 carat oval shape alexandrite displays a pronounced greenish to orangish color shift, with precise dimensions of 6.09 x 4.68 x 4.38 millimeters. The gem is faceted in a mixed brilliant cut, combining a brilliant crown with a modified pavilion facet structure, a choice that balances scintillation with color saturation to enhance the alexandrite effect under different lighting. The proportion profile yields a depth ratio of approximately eighty one percent, a geometry that preserves internal color zoning and provides strong face up color in both daylight and incandescent conditions. Clarity is graded slightly included at eye level, with small internal characteristics that do not materially reduce transparency, and the polish is excellent, indicating crisp facet junctions and smooth facet planes that contribute to superior light return. Color intensity is medium, a desirable range for alexandrite because it maintains distinct green and orangish tones without becoming overly dark, and there has been no enhancement, confirming a natural, untreated origin from Ceylon Sri Lanka.

Weight is a defining attribute of this stone, and the 1.03 carat mass materially affects both rarity and market value. Crossing the one carat threshold in alexandrite is significant, because alexandrite of gem quality is inherently scarce, and stones above one carat are proportionally rarer than smaller specimens, commanding stronger interest from collectors and connoisseurs. The oval outline also maximizes perceived size face up relative to weight, making this one point zero three carat stone present larger on the finger than a round of equivalent weight, while the mixed brilliant faceting concentrates light to emphasize the color change rather than simply increasing spread. The Ceylon provenance and the absence of heat or other enhancements further elevate collectibility, because natural, untreated alexandrite with a clear color change and good clarity is a premium attribute. For practical settings, the dimensions and depth support secure prong or bezel mounting that protects the stone while showcasing its optical behavior in varied lighting.
