1.42 Ct. Cabochon Alexandrite from Tanzania

Presenting an exceptional, translucent 1.42 carat oval alexandrite offered exclusively by The Natural Gemstone Company, a stone that embodies rarity and the subtle drama of color change. This cabochon has been shaped to elegant proportions, measuring 7.69 x 5.76 x 3.54 millimeters, and it displays a remarkable bluish green to reddish purple transition that is rare in cabochon faceting. Evaluated at eye level, the clarity is very very slightly included, a testament to the gemmaker's restraint in preserving natural character while achieving sublime optical clarity. The polish is excellent, the color intensity is intense, and there are no enhancements, confirming this alexandrite as an unaltered treasure from the famed deposits of Tanzania. This is not a mass produced offering, it is a singular gem for the collector or connoisseur who seeks an item of distinct provenance and personality.

What truly sets this alexandrite apart are the internal inclusions that form an unmistakable signature, a private language written within the crystal. Upon close inspection you will notice filaments of silk like inclusions, delicate and almost calligraphic, that trace soft, concentric patterns beneath the dome. These fine needlelike threads catch and scatter light in a way that deepens the color change, lending the green faces a watery depth and the red moments a painterly softness. Interspersed among the filaments are tiny crystal pockets and faint platelets that refract light into whispering flashes, producing a slender luminous band when the gem is viewed under a focused beam. That band is not a simple optical trick, it is an artifact of the stone s natural internal architecture, where aligned inclusions act like a private lens and create a refined chatoyant suggestion that appears and recedes with movement, illuminating the alexandrite s dual personality. These inclusions are not blemishes to be erased, they are the gem s fingerprint, a signature that guarantees uniqueness and assures the owner that this is a piece of nature s singular artistry rather than a laboratory uniformity.

Owning this alexandrite is to own a story and a quiet, exclusive club that very few will enter. At 1.42 carats with cabochon shaping that honors the stone s internal features, it is ideal for a bespoke ring, a sculpted pendant, or an heirloom brooch designed to reveal its color change at different moments of the day. Because it is untreated and of Tanzanian origin, it carries provenance and integrity that discerning collectors and bespoke jewelers prize. The Natural Gemstone Company presents this gem as a limited opportunity, reserved for clients who understand that true rarity is measured by character and history as much as by weight. We invite you to contact us for private viewings, custom mounting recommendations, and secure acquisition details. To hold this alexandrite is to hold a rare conversation between light and earth, a conversation whose punctuation is the subtle inclusions that define its identity, and whose ownership confirms your place among a select few who appreciate gemstones as living art.
