24.08 Ct. Violetish Blue Tanzanite from Tanzania

One beautiful transparent 24.08 carat cushion shape tanzanite, measuring 15.88 by 15.24 by 11.50 millimeters, presents a commanding presence that is rare in this species. The stone has been faceted in a mixed brilliant cutting style, combining the scintillation of a brilliant cut with the depth and fire that a well executed mixed cut can produce, and it exhibits a vivid violetish blue hue with exceptional saturation. Clarity is eye clean when evaluated at eye level, which means that under normal viewing conditions no inclusions are visible to the unaided eye, and the excellent polish enhances light return and surface luster. This tanzanite was heat treated, a standard and stable enhancement used throughout the trade to intensify the desirable blue violet tones, and its origin is Tanzania, a single source that confers both geological interest and market differentiation. The Natural Gemstone Company is pleased to offer this specimen as an example of what knowledgeable collectors and discerning clients seek when provenance, size, and visual performance align.

Color is the primary determinant of tanzanite value, and this stone’s rich, bold violetish blue speaks directly to personal power and distinction. The vivid color intensity indicates strong saturation without veering into darkness, keeping the stone lively and radiant in daylight and artificial lighting, and the violet component adds warmth and individuality that distinguishes tanzanite from pure blue gems. For an educated buyer, color is assessed by hue, tone, and saturation, and this gem ticks all three boxes, demonstrating a deep, appealing hue with a medium to medium strong tone and vivid saturation. Beyond aesthetics, the color also conveys symbolic resonance, with violet blue tones historically associated with leadership, intuition, and refinement, making this stone not only a visual statement but an emblem of personal authority and unique taste.

Cut and clarity together determine how effectively that color is communicated, and a 24.08 carat cushion with a mixed brilliant cut is an ideal canvas. The cushion outline provides a classic silhouette that flatters many settings, while the mixed brilliant faceting pattern balances broad flashes of light with a finely tuned return of fire and scintillation. Excellent polish means that facet junctions are smooth and reflective, minimizing light leakage and allowing the viewer to experience the full depth of the stone’s vivid color. The eye clean clarity grade, evaluated at eye level, indicates that the cutting cutter was able to work the rough material in a way that minimizes or eliminates visible inclusions, an important factor when considering large stones because inclusions can become more apparent as size increases. At the dimensions provided, the gem displays a substantial table and pavilion depth that contribute to its presence and optical performance, making it suitable for high end jewelry commissions or as a centerpiece for a collection.

For buyers who value transparency, provenance, and market wisdom, this specimen offers clear advantages. Tanzanite is found in a very limited geographic area in northern Tanzania, which underpins its scarcity and long term desirability, and large, clean stones of vivid color are proportionately rare, which supports collectability and potential appreciation. The heat treatment has been fully disclosed, it is stable, and it is universally accepted in premium tanzanite commerce, ensuring that the stone presents its best color while conforming to trade standards. The Natural Gemstone Company stands behind the quality and description of this gem, and we are able to provide guidance on appropriate settings, whether a bezel to protect the girdle and corners of the cushion, or a prong setting to maximize light entry and display color. Care recommendations include avoiding sharp blows, limiting exposure to extreme heat, and professional cleaning with warm water and mild detergent when necessary, which will preserve the polish and color. For the buyer seeking a statement piece that combines gemological substance with visual impact, this 24.08 carat cushion tanzanite is a compelling option that embodies bold color, technical precision, and clear provenance.
