4.50 Ct. Cabochon Tourmaline from Mozambique

This green tourmaline from Mozambique is a standout example of natural beauty and honest value, offered by The Natural Gemstone Company. This single translucent round cabochon weighs 4.50 carats, and measures 10.03 x 10.00 x 5.30 mm, presenting a satisfying size for many styles of jewelry. The cabochon cut has been executed with an excellent polish, creating a smooth dome that highlights the gems medium intense green, and its internal character. At eye level the clarity is described as very slightly included, and because the stone is translucent the inclusions add depth and uniqueness rather than detract from its appeal. Importantly this piece has no enhancement, a key distinction that preserves the natural color and structure of the crystal, and that adds confidence for buyers who prefer untreated material. The combination of very slightly included clarity, a medium intense green, and a high quality polish gives this cabochon an organic, saturated presence that feels both refined and authentic.

When compared to the common alternatives on the market this Mozambique green tourmaline holds distinct advantages. Versus emerald a green tourmaline offers a more durable everyday option, while still delivering a saturated green that reads as vibrant without the typical fragility and frequent oil treatments associated with many emeralds. Compared with peridot this tourmaline shows a greener, more stable tone with fewer yellow undertones, and it maintains its color more consistently under varied lighting. Against tsavorite garnet and green sapphire the tourmaline is usually more accessible in price at this weight and size, and its translucency and cabochon form present a different aesthetic that cannot be matched by the high brilliance of faceted stones, which sometimes emphasizes every inclusion. The fact that this gem is untreated elevates its rarity in the market segment of medium intense green stones, because many green gems are heat treated or irradiated to adjust hues, and untreated examples are increasingly prized by collectors and designers who seek authenticity and long term color stability.

Beyond the comparative value the physical properties and cut make this stone particularly versatile for design and wear. The cabochon shape softens the visual impact of inclusions and turns them into points of interest, creating a glassy, luminous surface that plays beautifully with light, while the substantial 4.50 carat weight and near perfect round dimensions ensure it sits confidently in rings, pendants, or bespoke pieces. Its hardness and toughness make it suitable for regular wear when set responsibly, and because it is natural and unenhanced the maintenance is straightforward, requiring only routine cleaning with mild soap and water, and occasional professional inspection of the setting. For those designing an heirloom quality piece the untreated origin from Mozambique adds provenance and story, as Mozambican tourmalines are known for attractive color range and responsible sourcing in recent years.

Choosing this cabochon from The Natural Gemstone Company means opting for a natural, untreated gem that offers a rare combination of size, color, and polish at a very fair value compared to many alternatives. For jewelry makers who want a stone that reads as naturally luxurious without the inflated price of tsavorite or the treatment concerns of some emeralds, this tourmaline presents a smart and beautiful choice. For collectors who value untreated material the eye level very slightly included clarity and the medium intense green provide character and authenticity that is increasingly sought after.
