1.58 Ct. Tsavorite Garnet from Madagascar

This 1.58 carat green tsavorite garnet from Madagascar is a study in precision cutting and color optimization, presented by The Natural Gemstone Company. The stone is fashioned in a classic emerald cut, with precise step facets arrayed in parallel planes across the crown and pavilion, and truncated corners that preserve the rectangular outline while reducing vulnerability at the girdle. The dimensions measure 8.10 x 5.27 x 4.05 mm, a proportion that balances an ample table with a proportionate pavilion depth to maximize internal reflectance. The cutter has chosen slightly elongated proportions to emphasize the vivid green hue, while maintaining symmetry that minimizes light leakage. The excellent polish on every facet junction produces crisp mirror planes, enhancing the hall of mirrors effect that is characteristic of a well executed emerald cut, and the result is a consistent window that frames the gem body color without the distraction of excessive surface milling.

Optical and material properties of this tsavorite have been preserved and augmented through careful preparation and controlled heat treatment, which has been applied to stabilize and intensify the vanadium and chromium derived green, without affecting the inherent transparency. The gem is graded as very very slightly included when evaluated at eye level, indicating inclusions that are minor and do not interrupt the clean visual field, which is particularly important for step cuts where inclusions can otherwise become visually prominent. Tsavorite garnet is anisotropic in chemical composition but is optically isotropic, which means it lacks pleochroism, so the cutter can orient facets to present the most saturated face up color. With an approximate refractive index in the grossular garnet family and a Mohs hardness in the vicinity of 7 to 7.5, this stone combines significant brilliance with practical durability for everyday wear, provided standard care is observed.

The cut architecture of this specimen is optimized for color saturation and controlled light return rather than aggressive scintillation, which is typical for step cuts intended to serve as a centerpiece. The broad table and successive facets of the crown channel light into broad zones of color, creating depth and the impression of a saturated, vivid intensity across the stone. The facet junctions exhibit high symmetry and consistent facet angles, resulting in uniform color zoning and minimizing windowing along the pavilion. The polish quality is classified as excellent, which contributes to crisp facet reflections and heightened apparent clarity. From a setting perspective, the stone’s pavilion depth and girdle proportions lend themselves to classic four or six prong settings or a tailored bezel that showcases the gem table while protecting the profile. In a three stone or solitaire setting, the emerald cut will read as a sophisticated, architectural element, placing the saturated green at the visual center of any composition.

For the connoisseur seeking technical excellence and aesthetic presence, this Madagascar tsavorite garnet represents a rare convergence of material quality and lapidary skill. The vivid color intensity, combined with the well controlled step cutting, yields a gem that projects consistent saturation under varied lighting, while the clarity grade ensures that the visual field remains open and clean. The heat treatment has been applied judiciously to enhance hue without compromising transparency or structural integrity. Whether evaluated for bespoke jewelry design, as a catalog centerpiece, or as a collector grade specimen, this emerald cut tsavorite articulates the principles of fine cutting and gemstone selection that The Natural Gemstone Company adheres to, offering a technically superior option for buyers who demand exacting proportions, exemplary polish, and a commanding presence in any collection.
