7.77 Ct. Cabochon Paraiba Tourmaline from Mozambique

This green paraiba tourmaline began as a secret held deep within Mozambican pegmatites, a mineral whisper that only the patient earth could translate into color. The copper and manganese that give this gem its vivid green hue gathered over millions of years, folding light into a vivid, oceanic green that is rare and unmistakable. Miners working in Mozambique, where this variety has become one of the most sought after sources outside of its Brazilian namesake, carefully extracted rough crystals that often show a range of internal textures and eventual beauty. The journey from rough to polished gem is a human one as well as a geological story, and this particular stone was selected for its clarity of color and its potential to become a standout jewel. The Natural Gemstone Company partners with trusted suppliers in Mozambique to trace each parcel, and this piece arrived at our workshop accompanied by a GIA certificate that documents the gem as a genuine paraiba tourmaline, confirming its identity and the presence of the heat enhancement that brings out the gems full personality.

In the hands of a skilled cutter, the rough crystal was measured and considered, and from that conversation with the stone emerged a 7.77 carat oval, measured at 13.05 x 11.01 x 6.44 mm, a pleasing scale that balances presence with versatility. Rather than the more common faceted approach, this tourmaline was fashioned into a double cabochon cut, a form that allows light to breathe through the gem and return as a soft, internal glow. The lab color classification is Green, with a medium intense color intensity that reads as luminous and alive without overpowering. At eye level the clarity is graded slightly included, and those modest inclusions become part of the gems story, a fine garden of natural features that testify to its authenticity and origin. The polish is excellent, a mirror smooth surface that amplifies the stone’s inner depth and provides a tactile, almost liquid quality to the green that makes the gem inviting to touch and captivating to behold. The GIA certificate accompanies this piece, noting the heat treatment enhancement that is a common and stable practice for paraiba tourmalines, used to refine and stabilize the color for lasting wear.

The crafting of this gem carried it from the mine to the lap of artisans who respect both the scientific and the poetic aspects of gemstones. After extraction in Mozambique, the rough was examined by experienced cutters who understand that a paraiba tourmaline is not simply a color, but a relationship between light, material, and form. The double cabochon shape was chosen to preserve weight while creating maximum internal color flow, and the cutter worked slowly to reveal the stone’s best planes and to manage the slight inclusions so that they enhance rather than distract. Once the shape was finalized, successive stages of fine polishing transformed the surface into the excellent polish that now allows the stone to act like a window into its own history. The GIA report that accompanies this gem documents the essential characteristics, and at The Natural Gemstone Company we include that report with the stone so that its provenance and treatment history are transparent. This transparency matters because paraiba tourmalines are treasured for their rarity, and a GIA certification gives collectors and designers confidence in what they are placing at the heart of a custom or finished piece.

For someone imagining this 7.77 carat green paraiba tourmaline in a finished jewel, consider its possibilities. Set as a solitaire pendant the oval 13.05 x 11.01 x 6.44 mm form will catch the light and rest against the skin with gentle presence, the double cabochon giving an internal glow that feels almost alive. In a bespoke ring setting the medium intense green will read as both modern and timeless, and the slightly included clarity will lend character and authenticity visible to a curious eye. Because the stone has been heat treated, it is stable under normal wear, but we recommend care to preserve its beauty, including avoiding harsh chemicals and extreme heat, and preferring gentle cleaning with warm soapy water and a soft cloth. Ultrasonic and steam cleaning methods are not recommended when inclusions are present, since those internal features can make the stone more vulnerable to sudden stress. If you would like this gem set or accompanied by a matching pair for a unique project, our team at The Natural Gemstone Company can assist with design, metal choices, and secure setting options that protect and highlight the cabochons distinctive glow. Owning a GIA certified paraiba from Mozambique is to carry a story of earth and craft, and this gem promises to be a centerpiece that connects you to that story for generations.
