1.29 Ct. Alexandrite from Ceylon (Sri Lanka)

This is a finely presented, transparent 1.29 carat alexandrite, faceted in a classic emerald cut, with dimensions 7.17 by 5.63 by 3.61 millimeters. The excellent polish and precise facet geometry give the stone crisp step facets and a broad table that showcases its color shift. This alexandrite displays a distinctive greenish to orangish color change, appearing more green under fluorescent lighting and taking on a warm orangish tone under incandescent light. The clarity is graded slightly included when evaluated at eye level, meaning there are small natural inclusions visible to a careful naked eye inspection, but they do not disrupt the gem's overall transparency or brilliance. This gem is untreated, with no enhancement, and it originates from Ceylon, Sri Lanka, a source known for producing lighter, often pastel toned alexandrites with elegant color change characteristics. The stone has an approximate depth of 3.61 millimeters, which corresponds to an overall depth proportion of approximately 56.4 percent relative to the average of its length and width, a proportion that contributes to its balanced weight distribution and face up appearance.

From a gemological perspective this alexandrite is a member of the chrysoberyl family and shares the durability that makes chrysoberyl a preferred choice for everyday wear. Alexandrite typically exhibits a relatively high refractive index, often in the range of about 1.74 to 1.76, which combined with its excellent polish enhances sparkle and color saturation even in a lighter tone stone. The phenomenon that defines alexandrite is the color change effect caused by trace chromium and the stone's selective absorption of light, a property that yields green to blue green tones in daylight and yellow to red tones in incandescent lighting. The emerald cut chosen for this piece is a particularly elegant choice for collectors and designers who wish to emphasize the gem's clarity and color zones. Emerald cuts provide broad, step facets that create controlled flashes of light and allow the color change to be observed across the table, while also demanding careful cutting to balance color distribution with light return. Slight inclusions visible at eye level can serve as natural identifiers of origin and authenticity, and in this specimen they sit harmoniously within the stone, adding character without significantly diminishing visual appeal.

For the educated buyer, a number of factors make this alexandrite noteworthy. First, the combination of 1.29 carats and transparent body color with a clear demonstrable color change is relatively uncommon in material from Sri Lanka, where alexandrites more often present in subtle pastel shifts. The light color intensity here keeps the gem elegant and wearable, while the evident change from greenish to orangish under different light sources provides the signature alexandrite experience. The absence of treatments or enhancements is particularly important for collectors and connoisseurs, since natural, untreated color change alexandrite is scarce and commands respect in the market. The emerald cut dimensions make this stone versatile for bespoke jewelry, suitable for a solitaire ring that highlights the color change, for a bezel setting that accentuates the clean lines of the cut, or for a halo design that increases perceived size while framing the unique hue shifts. The excellent polish and well executed faceting contribute to consistent light performance, meaning the gem will read true to its photographs and will behave predictably in a variety of lighting conditions. Origin from Ceylon is an important provenance detail, as Sri Lankan alexandrite has a distinct aesthetic that many collectors seek for its delicate and romantic color transitions.

Beyond the technical attributes, this alexandrite carries a romantic story born of its color and clarity, a narrative that resonates with buyers seeking emotional meaning in their jewelry. Imagine a Sri Lankan garden at dusk, where palms sway and lantern light begins to bloom, the leaves reflecting a cool green daylight tone. A young couple walks among the blooms, their laughter mingling with the soft hum of evening insects. As the sun sets and the lamps are lit, the garden shifts into warm amber and rose, and a small stone in a palm catches that changing light and seems to change with it. The inclusions within the stone are like tiny maps of that evening, microcosms of the earth that formed it, bearing witness to time and place. Worn as a promise, this alexandrite becomes a living memento of transition and devotion, a gem that mirrors the stages of a long love, green for growth and renewal, orange for warmth and enduring fire. The Natural Gemstone Company is proud to offer this piece with full disclosure of its characteristics and origin, and we view provenance and untreated status as essential parts of the story that make a gemstone more than a commodity, but a treasured heirloom with both geological and emotional provenance.

In practical terms this alexandrite is an excellent candidate for a custom engagement ring or an elegant everyday piece, given the hardness and toughness associated with chrysoberyl. The measurements 7.17 by 5.63 by 3.61 millimeters fit comfortably within classic ring settings, and the emerald cut will visually elongate the finger while allowing the wearer to appreciate the color change in both daylight and evening light. Collectors will value the natural, slightly included clarity as evidence of authenticity, and designers will appreciate the excellent polish and well balanced depth percentage for achieving secure settings with pleasing optical performance. If you seek a gem that combines scientific interest, durable wearability, collector appeal, and a romantic provenance inspired by the shifting light of a Ceylon twilight, this greenish to orangish alexandrite is a compelling choice, and The Natural Gemstone Company stands ready to assist with certification, custom setting options, and any further gemological details you require.
