9.15 Ct. Violetish Blue Tanzanite from Tanzania

This listing describes a single transparent tanzanite, weighing 9.15 carat, presented in a refined cushion shape. The stone measures 14.39 millimeters by 10.87 millimeters by 6.86 millimeters, and has been shaped with a mixed brilliant cut to balance scintillation and face up color. Clarity has been evaluated at eye level and graded as very slightly included. Color intensity is assessed as intense, displaying a pronounced violetish blue hue. The surface finish is described as excellent polish. Enhancement by heat treatment has been applied, and the gem is sourced from Tanzania. These attributes have been gathered and verified by The Natural Gemstone Company.

The mixed brilliant cut used for this tanzanite combines the broad, softer facets of a step influenced pavilion with a lively crown faceting that promotes dispersion and scintillation. In practical terms this results in a gem that presents a strong face up color while also delivering dynamic light return when viewed at different angles. Tanzanite is known for its pleochroic nature, and this specimen exhibits the characteristic interplay between violet and blue tones that shifts with orientation and lighting. The internal clarity grade of very slightly included indicates minor natural features that do not detract from the overall brilliance when viewed without magnification, and the excellent polish preserves crisp facet junctions and clean reflections across the table and crown facets.

This tanzanite is notably versatile in style application, suitable for both casual and formal settings. When set in a daily wear piece such as a pendant or a low profile ring, the intense color provides an elegant yet approachable accent that complements both relaxed and professional attire. For formal occasions the generous face size and cushion silhouette read as a statement piece when mounted in a classic four prong or three stone ring, or when paired with a delicate halo to enhance perceived size and increase sparkle under event lighting. Metal choices such as warm yellow gold, contemporary rose gold, or neutral white gold and platinum will each influence the presentation of the violetish blue, and the mixed brilliant cutting allows the gem to retain depth and visual presence regardless of the chosen setting.

Considerations for handling and long term care are practical and straightforward. Tanzanite typically ranks around 6.5 to 7 on the Mohs hardness scale, and therefore benefits from protective setting designs that reduce exposure to knocks and abrasion during active pursuits. Routine cleaning with warm soapy water and a soft brush is appropriate, and mechanical or ultrasonic cleaning should be approached with caution and discussed with a professional jeweler. Heat treatment applied to tanzanite is a widely accepted and stable enhancement, used to optimize the desirable violetish blue color, and it does not require special aftercare beyond standard gemstone handling. The origin from Tanzania remains a significant element of provenance, and The Natural Gemstone Company documents each specimen with clear descriptive information relating to weight, dimensions, cut, clarity assessment, color intensity, polish, enhancement and origin, to support an informed selection.
