4.75 Ct. Cabochon Tourmaline from Mozambique

One beautiful translucent 4.75 carat round green tourmaline is presented here, measuring 9.97 by 9.97 by 5.64 millimeters, cut as a smooth cabochon with an excellent polish. The medium intense green color displays an appealing balance of saturation and brightness that reads very naturally to the eye, without appearing too dark or overly vivid. This piece is offered as a completely natural specimen, with no enhancement, and is identified to originate from Mozambique, a region that has become notable for producing fine tourmalines with attractive color and generally good clarity. The cabochon shape suits this material exceptionally well, as it emphasizes the gem’s translucency and internal glow, creating a rich visual presence in wearable jewelry such as rings and pendants, or as a curated collector’s piece for an educated buyer.

Clarity has been assessed as very slightly included, evaluated at eye level, which in practical terms means the stone exhibits only minor inclusions visible without magnification under normal viewing conditions. These very slight inclusions are typical in natural tourmaline and do not materially affect the gem’s structural integrity or its overall beauty. In the context of tourmaline grading, a very slightly included designation sits well above more heavily included grades and is often preferred by buyers who want a natural appearance with minimal visual distractions. Because the gem is translucent rather than fully transparent, the cabochon polishing and dome shape work together to mask small internal features while enhancing color depth and internal luster, which is why the excellent polish grade is important for maintaining a clean surface appearance and superior light response.

The origin of a gemstone contributes significantly to informed valuation, and Mozambique has developed a strong reputation in recent decades for producing high quality tourmaline crystals in a range of hues. While green tourmalines can derive their color from different trace elements, the critical points for valuation are color tone, saturation, and whether the stone is natural and untreated. This tourmaline’s medium intense green and the absence of any enhancement make it particularly attractive to collectors and connoisseurs who prioritize natural gem material. No heat treatment, irradiation, or dyeing has been applied, which preserves both the gem’s natural character and its market value. The cabochon cut itself is a deliberate choice for a translucent green tourmaline, as it maximizes the perception of depth and yields a smooth, comfortable profile for daily wear, while the nearly 10 millimeter diameter and 4.75 carat weight provide a noticeable presence without being oversized.

For practical considerations, tourmaline ranks approximately 7 to 7.5 on the Mohs hardness scale, offering good durability for many jewelry settings provided it is handled with reasonable care, avoiding hard knocks and extreme thermal shock. The gem’s polished cabochon dome is well suited for bezel settings or protective designs that highlight color while minimizing exposure of the high-domed surface to potential abrasion. From a buyer’s perspective, factors that determine market value include the natural, untreated status, the clarity grade of very slightly included as evaluated at eye level, the medium intense hue and evenness of color, the quality of the polish, and provenance from a reputable source such as Mozambique.
