4.54 Ct. Cabochon Tourmaline from Mozambique

This offering from The Natural Gemstone Company is a beautifully transparent green tourmaline weighing 4.54 carat, presented in a cushion shape with dimensions 8.46 by 8.29 by 7.37 mm, and finished in a distinctive sugar loaf cut. The sugar loaf form produces a gently domed crown with prominent, subtly faceted planes that create a deep, rounded table and soft reflective zones, a style that concentrates color and yields a richly saturated appearance under most lighting conditions. The cushion outline is versatile and classic, suited to both traditional and contemporary settings, and the proportions here favor hand set bezels, prong work, and bespoke artisan mounts. At this size and with such symmetry, the stone reads well both as a single statement gem and as the centerpiece in a more complex design, and the dimensions translate to a comfortable face up presence while maintaining proportions that will sit securely in custom jewelry work.

From a clarity and finishing perspective this tourmaline is graded very slightly included, evaluated at eye level, and carries an excellent polish. The very slightly included grading indicates that at regular viewing distance the stone displays only minor internal characteristics that do not distract from the overall visual impression, and these inclusions are typical of natural tourmaline crystallization, often manifesting as fine needles or pinpoint crystals rather than fractures. Because the polish is excellent, light transmission is optimized and the cut surfaces deliver clean reflections and crisp highlights, which enhances perceived brilliance and depth. The medium intense color intensity is an important factor for educated buyers, as it represents a sweet spot for green tourmaline where the hue is clearly present without veering into overly dark tones that can reduce sparkle. The gem is reported to have no enhancement, a distinction that increases its appeal for collectors and connoisseurs who value untreated material, because the color, clarity, and optical properties are wholly natural and stable under normal wear and exposure.

The origin of this tourmaline is Mozambique, a source that has become well regarded for producing transparent and richly colored tourmalines in a range of hues, particularly vibrant greens and blues. Geographic provenance is relevant to the educated buyer because it informs geological context, potential zoning characteristics, and the supply story that underlies rarity and market value. Mozambique specimens often show clean crystalline growth and attractive natural color distribution, and this example exemplifies those traits, with a medium intense green that benefits from the sugar loaf shaping to showcase saturation without sacrificing light return. Tourmaline is a durable gem suitable for everyday wear with a Mohs hardness around 7 to 7.5, and the absence of enhancement means predictable care behavior, though it is always advisable to clean with warm soapy water and avoid prolonged exposure to harsh chemicals or extreme heat. For buyers seeking investment grade or museum quality natural stones, this 4.54 carat Mozambique green tourmaline represents a balance of weight, color, clarity, and provenancing, and The Natural Gemstone Company stands behind its description and is available to assist with mounting recommendations, certification pathways, and bespoke consultation to integrate this gem into a design that preserves its beauty and value.
