2.01 Ct. Cabochon Alexandrite from Tanzania

This translucent 2.01 carat oval alexandrite presents a rare combination of material integrity and visual drama, a gemstone that reads as a statement of personal power and distinction. The stone is fashioned as a cabochon, with an oval outline that measures 5.17 x 7.30 x 4.83 mm, and it exhibits a rich, bold color that shifts from a greenish aspect to a brownish aspect depending on the light source. The color change is immediate and legible, not subtle, and the intensity of color is graded as intense, which enhances presence when set in jewelry. This specimen is of Tanzanian origin, it is natural with no enhancement, and it has been evaluated with a clarity grade of very slightly included at eye level, a clarity profile that preserves the alexandrite effect while maintaining clean visual fields and strong color saturation.

From a gemological perspective, the cabochon cut has been executed to optimize the color change phenomenon inherent to alexandrite, rather than to maximize facet brilliance. The dome height and symmetry have been controlled to allow a broad, even color field across the top, so that the greenish tones in daylight present with even distribution, and the brownish tones under incandescent lighting appear uniform without patchiness. The polish is excellent, indicating careful final lap work, and surface condition shows no lapping marks or polish haze that could scatter light and dilute the color response. The very slightly included clarity grade reflects minor internal features that are not distracting to the unaided eye, and those inclusions are internal, stable, and do not compromise durability. For reference in handling and setting, alexandrite has a Mohs hardness in the high range for corundum group chrysoberyl materials, and its specific gravity and refractive properties are consistent with classic alexandrite, contributing to its stable performance in standard jewelry settings.

Color grading for alexandrite requires attention to hue, tone, and saturation, and this piece scores highly across those axes. Under balanced daylight or a cool white source, the dominant hue reads greenish with a saturated tone, while under warm incandescent illumination the dominant hue shifts toward a brownish red leaning palette, with the color change described as strong. The transition is governed by chromium chromophore absorption bands interacting with the cut geometry, and in a cabochon the dome allows color fields to develop rather than fractured light play. The intensity classification of intense denotes high saturation and relatively deep tone, which in practice translates to immediate visual authority and the ability to function as a focal element in bespoke jewelry. The absence of any enhancement means the color is entirely natural, the result of trace element chemistry and the original crystal environment in Tanzania, and this provenance informs both market perception and collector value.

The Natural Gemstone Company offers this alexandrite to connoisseurs seeking a piece that communicates distinction through material substance, rather than ornament alone. From a setting and design perspective, the stone is well suited to bezel and collet settings that protect the cabochon rim and preserve the even color fields, and it will perform well in signet or statement ring formats where the strong color and translucency can be appreciated against skin tone. We recommend secure mounting that allows light to reach the crown in both cool and warm contexts to showcase the color shift, and a setting design that frames but does not overly decorate the stone, so the rich, bold color remains the principal visual message. The Natural Gemstone Company certifies that this alexandrite is natural, unenhanced, and supplied with documentation of origin and the parameters measured during our evaluation, and we welcome inquiries for custom mounting options, detailed spectral reports, and comparison viewing against other alexandrite specimens, for buyers who wish to experience the tactile and optical qualities in person.
