28.43 Ct. Cabochon Tanzanite from Tanzania

Born from the slow alchemy of the earth in the hills of Tanzania, this translucent violet tanzanite carries the memory of deep geological time to the present, as described by The Natural Gemstone Company. We first encounter the rough in narrow seams where miners carefully extract crystals from ancient metamorphic rock, then pass them to artisans who reveal the stone within. This example is a substantial 28.43 carat round cabochon, measuring 15.81 x 14.64 x 12.91 mm, with intense color intensity, a clarity grade of included evaluated at eye level, and an excellent polish. Heat treated to stabilize and deepen its violet hue, the gem retains internal features that give it character and depth, allowing light to diffuse within the dome of the cabochon and produce a soft, glowing presence. The cutting and polishing process is a patient conversation between cutter and material, priority given to preserving weight and showing off the rich violet, while the cabochon profile emphasizes the stone s translucent body and organic inclusions, telling a story of origin and craft.

When imagining this tanzanite in a custom piece, the jewel comes alive through thoughtful contrasts and harmonies. Set in cool platinum or white gold, tiny round white diamonds or white sapphires will frame the cabochon, adding pinpoint brilliance that contrasts with the stone s soft glow, ideal for a pendant that reads regal and modern. For a warmer, more intimate design, rose gold paired with small morganites or pink sapphires will flirt with the violet and introduce a romantic warmth. For a bold color narrative, place small green tsavorite garnets or chrome diopside as accent stones to generate a striking complementary contrast, or flank the tanzanite with deep blue sapphires to create a graduated violet to blue sweep. A protective bezel setting will honor the cabochon shape and suit daily wear, while a delicate halo of melee diamonds will increase perceived size and presence for special occasion pieces. Wherever you choose to place this tanzanite, The Natural Gemstone Company is ready to guide you through metals, accent stones, and setting styles to translate the gem s Tanzanian journey into a wearable story that reflects your taste and the gem s singular character.
