2.17 Ct. Alexandrite from Tanzania

This transparent 2.17 carat cushion shape alexandrite presents a classic and highly desirable color change, shifting from a greenish hue in daylight to a warm orangish tone under incandescent light. The gem measures 6.27 x 6.16 x 5.82 mm, and its mixed brilliant cut is designed to maximize both scintillation and color change, balancing multiple facet angles to return strong brilliance without sacrificing the stone’s characteristic shift in hue. With a medium color intensity and an excellent polish, the surface finishes have been executed to enhance light return and saturation, while the clarity is graded as very slightly included, evaluated at eye level, indicating only minor inclusions that do not materially detract from visual appeal or transparency when viewed unaided. There has been no enhancement, which preserves the stone’s natural character, and the material is identified as originating from Tanzania, a source increasingly recognized for producing fine alexandrite specimens.

From a gemological and buyer perspective, this alexandrite offers several points of value. The color change phenomenon itself is rare and prized, and when combined with a clean, transparent body and a precision mixed brilliant cut, it produces a stone that performs beautifully in jewelry while retaining investment appeal. Alexandrite is a variety of chrysoberyl, and on the Mohs hardness scale it rates at approximately 8.5, which places it well above common jewelry gems such as quartz and ensures strong resistance to abrasion during regular wear. Its toughness and lack of perfect cleavage make it suitable for everyday pieces including rings, though sensible care is still advised to avoid sharp blows and harsh chemicals. The absence of enhancements preserves provenance and future resale integrity, and Tanzanian origin contributes positively to rarity narratives for educated buyers who value traceable sources. At The Natural Gemstone Company we provide exact measurements, transparent grading notes, and can assist with independent laboratory reports on request, supporting informed purchases and long term confidence in the gem’s authenticity and suitability for both fine jewelry and collector holdings.
