0.72 Ct. Purple Sapphire from Tanzania

This listing describes one transparent 0.72 carat fancy shape purple sapphire, with exact dimensions of 5.65 by 5.55 by 4.20 mm, presented by The Natural Sapphire Company. The sapphire displays a medium color intensity in a true purple hue, and it is wholly natural in origin, sourced from Tanzania. Enhancement status is no enhancement, and the gem is offered in an untreated state, preserving its natural color and structure. The combination of weight, dimensions, and color yield a stone that is compact yet visually impactful, suitable for a focused single stone setting or as the central element in a multi stone composition. Photographs supplied show the sapphire in multiple orientations and include scale images to demonstrate hand scale, allowing for an accurate appreciation of size and proportion prior to setting.

The cut is a mixed brilliant cut executed on a nonstandard fancy outline, and it is a defining characteristic of this sapphire. A mixed brilliant arrangement combines a step style arrangement in the pavilion with brilliant style crown facets, producing a balance between depth of color and scintillation. This particular cutting geometry has been carefully applied to the rough to optimize light return, and the faceting pattern produces an even distribution of brilliance across the table and crown. The stone exhibits crisp facet junctions and controlled symmetry, which together contribute to a lively interplay of light within the body of the gem. With an excellent polish, facet surfaces are smooth and reflective, enhancing the visual impression of fire and brightness. The result is a sapphire that reads clearly as a centerpiece, with the mixed brilliant cut maximizing both internal sparkle and the perception of color saturation without overdeepening the tone.

Clarity has been graded as very very slightly included, evaluated at eye level, and the stone presents as transparent with inclusions that do not detract from its overall visual appeal under typical viewing conditions. These minute internal characteristics are consistent with natural corundum from the region of origin and are visible only under magnification or upon close inspection in specific lighting. The medium color intensity allows the purple hue to remain vibrant while retaining versatility for jewelry design, making it compatible with both platinum and yellow metal mountings. As corundum, the sapphire benefits from a high degree of hardness and structural stability, which makes it suitable for everyday wear when properly set. The lack of any heat or other enhancement preserves the natural crystal habit and internal features, attributes often valued by collectors and connoisseurs who prioritize untreated material.

The Natural Sapphire Company has documented the key gemological data for this sapphire to support informed selection and design decisions. The stone’s dimensions and pavilion depth have been considered in recommending mounting options that will protect the girdle and table while showcasing the cut. Prong settings allow maximum light exposure to the crown and table, accentuating brilliance and allowing the mixed brilliant facets to operate fully, while bezel settings offer increased protection for active wearers and can be designed to reveal a controlled band of color around the perimeter. For use as a solitaire or the focal stone in a cluster or halo, the sapphire’s unique fancy outline and proportionate size make it adaptable to contemporary and traditional design languages. Additional information, including detailed images, exact weight, and handling recommendations, is available upon request from The Natural Sapphire Company, and we can provide guidance to ensure the stone is set to preserve its visual qualities and long term stability. In summary, this 0.72 carat Tanzanian purple sapphire combines a considered mixed brilliant cut, excellent polish, transparent clarity, and untreated origin, creating a well proportioned and brilliant gemstone capable of serving as a distinguished centerpiece in a high quality jewelry piece or collection.
