9.80 Ct. Cabochon Tsavorite Garnet from Tanzania

At The Natural Gemstone Company we are pleased to present one exceptional semi transparent tsavorite garnet, weighing 9.80 carat, and fashioned into a classic cushion shape. The stone measures 13.05 by 11.22 by 8.00 mm, and it has been given a sugar loaf cut that accentuates its rich green depth. This gem exhibits vivid color intensity and an excellent polish, and its clarity is graded as included when evaluated at eye level. There has been no enhancement applied, and the piece originates from Tanzania, a well respected source for fine green grossular garnets. These combined attributes create a strong visual impact, with a saturated green that remains bright and lively under a range of lighting conditions.

From a gemological perspective this tsavorite represents the important qualities that educated buyers seek. Tsavorite is a green variety of grossular garnet, with its color derived primarily from trace chromium and vanadium, and it typically presents a refractive index in the range associated with garnet species and a specific gravity that gives the stone a satisfying heft on the finger. Its Mohs hardness of approximately 7 to 7.5 provides good daily wear durability when properly set. The sugar loaf cut is intentionally domed and smooth, which maximizes the perception of color intensity in stones that are semi transparent, rather than prioritizing faceted brilliance. The excellent polish on this piece ensures clean reflections and surface finish, while the cushion outline offers versatile styling potential for a classic solitaire or a more contemporary halo setting.

Clarity and inclusion patterns are an important part of understanding value and character in natural tsavorite, and this stone is graded included at eye level. That means there are internal features visible without magnification, which is commonly encountered in larger, untreated tsavorites. Typical inclusions in gems of this type include crystal growth features, tiny mineral crystals, and fine feathers or needles, and these internal signatures often confirm a natural, unheated origin. For the discerning buyer, the combination of bright, vivid green color, substantial 9.80 carat weight, and natural condition with no enhancement can be more attractive than smaller flawless stones, because sizable, untreated tsavorites with strong color are comparatively rare. Provenance from Tanzania further supports its market position, as East African deposits have produced many of the most desirable vivid green tsavorites in recent decades.

For practical use and long term enjoyment consider a setting that protects the girdle and any surface reaching, such as a secure bezel or robust prong design, particularly because the sugar loaf profile benefits from a protective mount. Routine cleaning is straightforward, using warm soapy water and a soft brush, while avoiding harsh chemicals and extreme thermal shock. Ultrasonic cleaning may be acceptable for well stabilized stones, but should be avoided if the included features extend to surface reaching fractures. At The Natural Gemstone Company we document origin, treatment status, and the detailed measurements and grades provided, and we are available to supply additional photography, condition reports, or independent third party certification upon request. If you value natural color, substantial carat weight, and the assurance of no enhancement, this Tanzanian tsavorite warrants close consideration as a special addition to a refined gemstone collection.
