1.20 Ct. Rhodolite Garnet from Tanzania

This listing presents a single, transparent 1.20 carat rhodolite garnet, cut in a refined emerald shape, with dimensions 5.84 by 4.92 by 4.11 millimeters. The gem displays a purplish red hue with intense color intensity, a result of the balanced pyrope and spessartine composition that defines rhodolite garnets. Origin is Tanzania, and no enhancement has been applied, which is an important attribute for collectors and connoisseurs who prioritize natural color and stability. The cut is an emerald style, executed with precision to emphasize the stone's color and clarity while producing broad faceted planes that confer a sophisticated, architectural look. The overall presentation is of a gem that combines compact size with visual impact, suitable for a variety of settings from classic solitaire rings to bespoke pendant designs, and it is offered to you by The Natural Gemstone Company.

Clarity is graded as very slightly included, evaluated at eye level, which for practical purposes means that the stone reads clean to the unaided eye under normal viewing conditions, with only minor, well seated inclusions visible at certain angles or under magnification. The excellent polish enhances the smoothness of facet junctions, which in turn supports superior light return and a crisp appearance under both direct and diffused lighting. From a gemological perspective, this clarity and polish combination allows the intense purplish red color to remain pure and evenly distributed across the crown and pavilion. The absence of enhancement techniques, such as heat or dye, confirms that the visual qualities are inherent to this Tanzanian rhodolite, which increases both desirability and long term value for an educated buyer who values natural provenance and untreated gemstones.

The optical performance and remarkable sparkle of this rhodolite arise from both its internal atomic structure and the way it has been faceted. Garnets crystallize in the isometric system, which makes them optically isotropic and free from pleochroism and birefringence, so their brilliance is driven primarily by a relatively high refractive index rather than by double refraction effects. Rhodolite varieties commonly exhibit refractive indices in a range that is appreciably higher than quartz and many other common gem materials, which concentrates the light back to the viewer as strong, lively return. In addition, the emerald cut emphasizes broad, parallel facets that act like mirrors, producing flashes of concentrated color and light that sweep across the stone as it moves. The step facets create a dynamic interplay between deep color zones and bright facet windows, allowing the intense purplish red to manifest both saturated depth and scintillating highlights. The combination of high index, precise facet geometry, and excellent polish yields a type of sparkle that is at once deep and lively, and that differs from the pinpoint brilliance of brilliant cuts because it emphasizes color contrast and broad flashes of reflected light, which many collectors describe as a pleasing, elegant scintillation.

For practical considerations and long term enjoyment, rhodolite garnet is a stable, wear friendly gem with good toughness and a Mohs hardness that commonly sits around seven to seven and a half, making it suitable for most fine jewelry applications when set with appropriate care. The stone is resistant to most household chemicals and does not require special lighting to show its best color, though it will appear warmer and more vivid under incandescent and warm LED lighting. As an untreated, transparent, and well cut example from Tanzania, this 1.20 carat emerald cut rhodolite garnet represents a high quality natural choice for someone seeking a statement piece with both gemological integrity and aesthetic refinement. The Natural Gemstone Company is pleased to present this gem to buyers who appreciate documented origin, natural color, and expert cutting, and we invite you to consider this stone for a custom design or as a distinctive addition to a curated collection.
