4.61 Ct. Cabochon Tourmaline from Mozambique

This listing presents a single translucent green tourmaline, offered by The Natural Gemstone Company, weighing 4.61 carats, with an oval outline and cabochon faceting. The gem measures 11.03 by 9.07 by 5.14 mm, and it has been evaluated with a clarity grade of very slightly included, based on observation at eye level. The color is described as vivid in intensity, exhibiting a clear, saturated green tone across the dome of the cabochon, and the surface finish has been assessed as excellent polish. No enhancement has been applied to this specimen, and its reported origin is Mozambique, a region known for producing vibrant tourmaline material with attractive color and stability.

Visually, the stone presents a deep, lively green that reads slightly different depending on the angle of view and the direction of light transmission, a characteristic typical of translucent tourmaline cabochons. The cabochon cut produces a smooth domed top that emphasizes color and translucency rather than brilliance. Included features are present at a very slight level, and they manifest as small, naturally occurring internal growth structures and occasional mineral inclusions that are consistent with an unenhanced, natural origin. These internal characteristics are modest in extent, and they contribute to the gem’s natural appearance without significantly diminishing its visual appeal when viewed unaided. The excellent polish enhances surface luster and helps the cabochon display even, lively color distribution across the curved surface.

From a gemological and practical perspective, the cabochon shape and the stated proportions make this tourmaline appropriate for a variety of jewelry applications, particularly settings that protect the girdle and back of the stone. The dimensions and weight support use in ring designs with secure bezel or partial bezel settings, as well as in pendants and brooches where the dome can be appreciated visually without excessive exposure to wear. Tourmaline has a Mohs hardness of approximately 7 to 7.5, which provides reasonable durability for everyday jewelry when properly set and cared for, but it is not as hard as sapphire or diamond. Given the gem’s translucency and internal features, settings that minimize direct impact and protect the stone from hard knocks are preferable to preserve the integrity of the cabochon over time.

Handling and care recommendations are practical and conservative. Clean with warm water, a mild detergent, and a soft brush, rinsing thoroughly and drying with a soft cloth. Avoid steam cleaning and ultrasonic cleaning techniques, particularly because the internal characteristics of a natural, unenhanced cabochon can trap moisture or respond poorly to rapid thermal changes and strong vibrations. Avoid prolonged exposure to high heat and to harsh chemicals or acids that can affect polish and color stability. The Natural Gemstone Company can provide additional information on provenance documentation, and we offer assistance with custom mounting and setting advice to ensure the stone is presented securely and in a manner that complements its oval cabochon form and vivid green color.
