3.60 Ct. Cabochon Alexandrite from Tanzania

There are stones that behave like memories, changing with the light and whispering different stories as the hours pass, and this 3.60 carat oval alexandrite is one of those rare, living jewels, freshly surfaced from Tanzania and offered by The Natural Gemstone Company. Translucent and cut as a smooth cabochon, it measures 8.87 by 6.95 by 5.97 mm, and it carries an intense color presence that shifts from a vivid green in cooler, fluorescent light to a warm purplish red beneath incandescent glow, a private aurora captured inside a single oval. Slightly included when examined at eye level, those internal markings do not detract, but rather lend depth and personality, caught like whispers within the dome, and the polish is excellent, allowing a soft, silky reflection that seems to breathe. Untreated and natural, with no enhancement, this alexandrite is a rare conversation between mineral and light, a gem that feels at once antique and utterly new, perfect for someone who wants a jewel with a soul and an undeniable technical pedigree.

Imagine that living color cradled in settings that range from whispering minimalism to ornate heirlooms, because the cabochon profile of this stone invites a wide repertoire of designs and placements. A low bezel will protect the height and hold the stone safely for everyday wear, while an open back or a halo of tiny melee diamonds will allow light to play through and emphasize the color change, and a closed back in warm gold will deepen the purplish red character for evening pieces. For rings a bezel cup with a depth of roughly 6.5 mm will comfortably house the 5.97 mm dome, and a balanced shank of two to three millimeters creates a delicate solitaire, while a broader split shank can support a more dramatic vintage framework. For pendants the stone becomes a moonlit focal point with a custom bail that tilts the oval east west to reveal both green and red faces as it moves, and a simple bezel pendant will be an elegant daily talisman. Earrings can be matched as twin moons or composed as asymmetric drops, paired with small sapphires or tsavorites to echo the green tones, and bracelets can borrow cabochon stations that sit flush against the wrist for tactile comfort. Tension settings are generally not recommended for rounded cabochons, however a skilled jeweler can create custom prong overlays or a shadow bezel to secure the stone without hiding its luminous body. Metal choices are a silent chorus, with platinum or white gold clarifying the green, yellow gold warming the red, and rose gold softening transitions into a romantic pink glow.

As you imagine the possibilities, know that The Natural Gemstone Company stands ready to translate this stone into a thousand intimate designs, from modern solitaires to heirloom lockets with filigree and hand engraved signatures, from bezel set engagement rings to pendant lockets lined in silk. We can collaborate on accent choices, propose proportions so that the cabochon reads perfectly on the finger or at the throat, and provide recommendations for a custom setting that respects the stone height and its slight inclusions while preserving the color change that gives it life. For everyday care we suggest gentle cleaning in warm soapy water and a soft cloth, and avoiding ultrasonic cleaners or steam because natural inclusions can be sensitive to harsh vibration, and as with any finely cut cabochon avoid sharp knocks against hard surfaces. If you would like the stone set with a halo or with accent gems, or wish to request a certificate of origin and a detailed report, we will walk you through metal samples, sketches, and mounting options until the piece feels like it was always meant to exist. In the hands of a thoughtful designer this Tanzanian alexandrite will become a wearable poem, a changing light kept close, and we at The Natural Gemstone Company are honored to help you bring that poem into being.
