2.90 Ct. Cabochon Alexandrite from Tanzania

This translucent 2.90 carat oval alexandrite measures 9.65 x 8.49 x 3.28 mm, and it has been shaped into a smooth cabochon to best display its classic color change phenomenon. Under daylight and fluorescent lighting it reads yellowish green, while under incandescent light it shifts toward a reddish green, a signature trait of genuine chrysoberyl alexandrite. The gem is graded slightly included at eye level, with inclusions that do not compromise its overall translucency or surface appeal. Color intensity is medium, and the piece displays an excellent polish that enhances light return and the perception of depth within the cabochon dome. There has been no enhancement, and the stone is documented as originating from Tanzania. With a Mohs hardness around 8.5 chrysoberyl alexandrite is durable enough for everyday wear in rings and other jewelry, and the cabochon cut here is intentionally chosen to amplify the color change and deliver an even, luminous face to the observer.

For the educated buyer, this alexandrite represents a balanced combination of gemological integrity and visual presence. At 2.90 carat size, the stone is substantial for an alexandrite, where larger sizes command a premium due to natural scarcity. The slightly included clarity grade reflects natural growth features rather than treatments, and the absence of enhancements increases the gem's value for collectors who prioritize provenance and natural state. Tanzanian origin adds provenance value, as buyers increasingly seek stones with documented source information. The medium color intensity is often preferred by connoisseurs who value a clear, readable color change rather than an overly dark saturation that can mute the shifting hues. The rich, bold color of this alexandrite serves as a symbol of personal power and distinction, making it an ideal choice for a signature ring or a bespoke commission intended to function as an heirloom. The Natural Gemstone Company offers this specimen to clients who appreciate precise measurements, honest grading, and the enduring appeal of an unheated, well finished alexandrite that combines durability with a captivating chromatic shift.
