2.03 Ct. Green Grossular Garnet from Tanzania

This example of green grossular garnet offered by The Natural Gemstone Company is a transparent, oval shaped gemstone weighing 2.03 carats, with clean dimensions of 8.00 by 6.04 by 5.33 millimeters, sourced from Tanzania, and presented with no enhancement. The gem exhibits a medium color intensity in a fresh apple to lime green range, a clarity graded as very slightly included, evaluated at eye level, and an excellent polish that leaves facet junctions crisp and reflective. The mixed brilliant cut chosen for this stone is deliberate, combining a faceted crown that follows brilliant facet geometry, with a pavilion that incorporates both brilliant and modified step elements, to achieve a balance between spectral dispersion, overall brilliance, and color saturation. These baseline characteristics make this grossular garnet a naturally vivid, durable gem, with properties typical of this species, including a refractive index in the neighborhood of 1.740 to 1.760, an isometric crystal system that does not produce birefringence, and a practical hardness that allows secure everyday wear with appropriate mounting choices.

The mixed brilliant faceting of this oval garnet is central to how the stone handles light, and a technical look at the facet architecture explains the visual performance. The crown is cut with a series of kite and star facets that direct incident light laterally and towards the pavilion, creating a field of small, bright flashes known as scintillation. The pavilion integrates both pavilion mains that are inclined to maximize total internal reflection, and secondary step modified facets that act to redirect light that would otherwise leak away. This combination increases the probability that dispersed wavelengths will be reassembled and returned through the crown, enhancing perceived brilliance and creating lively color flashes as the stone is moved. The moderate table and proportioned crown heights allow for a balance between white light return and saturation of the green hue, while the cutter has optimized crown and pavilion angles to avoid excessive windowing, so that light entering the table encounters successive reflective events rather than passing straight through. An excellent polish across all facets minimizes surface scattering, while precise facet junctions preserve sharp contrast between bright and dark areas, a necessary component of a strong pattern and crisp scintillation in an oval mixed brilliant cut.

Proportions play a major role in this gem, and the measured depth of 5.33 millimeters relative to the average diameter of 7.02 millimeters yields a depth percent of approximately 75.9 percent, which is on the deeper side for an oval. Rather than being a detriment, in this particular stone the deeper pavilion works in tandem with the mixed brilliance pavilion design to intensify color saturation and to create multiple internal light returns that read as increased depth of color and lively internal flashes. The cutter has compensated for potential face up size loss by ensuring pavilion facets meet at angles that favor return rather than escape, and by maintaining symmetry across the oval outline to keep the bow tie effect minimal. The oval outline itself is slightly elongated, providing a broad table that presents the green color uniformly face up, and the very slightly included clarity grade means that inclusions are few, small, and do not disrupt the overall optical performance under normal viewing. Taken together, the dimensions, depth, and mixed brilliant faceting produce a gem that yields a pleasing mix of brilliance, dispersion, and saturated green, suitable for a focal piece in a ring or pendant where controlled light exposure will emphasize its best attributes.

From a practical and design perspective, this 2.03 carat Tanzanian grossular garnet is well suited to settings that allow ample light access to the pavilion and table, and that highlight the oval mixed brilliant silhouette. Open four prong or gallery style mountings will keep the pavilion exposed to light while protecting the girdle, and the warm to neutral green tone responds beautifully to both yellow gold and rose gold, which tend to enhance the gem’s warmth, or to white gold and platinum, which emphasize the stone’s crisp brilliance and cooler green undertones. Because there is no enhancement, the color and clarity are stable under normal wear and cleaning, and the excellent polish ensures that routine cleaning will restore full sparkle. For clients seeking a precisely cut natural green garnet with technical merit, The Natural Gemstone Company can provide additional documentation on cut angles and a video showing the stone in motion, and we can recommend mounting options that preserve the optical effects engineered into this mixed brilliant cut. This stone represents a finely executed marriage of material quality and faceting technique, designed to maximize light reflection, deliver strong scintillation, and present a saturated natural green that will perform reliably as a centerpiece in a variety of bespoke jewelry designs.
