1.09 Ct. Bluish Green Sapphire from Tanzania

One transparent 1.09 carat oval bluish green sapphire is presented with precise dimensions of 6.60 x 5.80 x 3.42 mm, offering a balanced length to width ratio that emphasizes the gemstone natural proportions. The gem is cut in a mixed brilliant style, combining a faceted crown and pavilion arrangement that is selected to maximize both internal light return and face up color, resulting in lively scintillation and an even spread of hue across the table. Color is described as bluish green with an intense color intensity, a saturation level that reads as vivid in both daylight and artificial illumination, while the surface finish is graded as excellent polish, producing crisp facet junctions and lively reflections. Clarity is graded as very slightly included when evaluated at eye level, indicating minor internal characteristics that do not materially detract from brightness or overall visual appeal, and the gem displays clean transparency that allows light to penetrate and interact with the cutting geometry.

This sapphire originates from Tanzania, a known source of richly colored natural corundum, and it is supplied with no enhancement, which confirms the stone is in its natural state with original color and structure intact. The absence of heat or other treatments preserves the natural color zoning and crystal habit, aspects that are important to both collectors and those seeking an untreated gemstone. As a sapphire, the material is corundum with a Mohs hardness of 9, making it highly resistant to abrasion and suitable for everyday wear when set in properly designed jewelry. The combination of an intense natural color, excellent polish, and a mixed brilliant cut produces a balance of tone and sparkle that supports both presence and discretion, and the very slightly included clarity means the eye perceives the gem as clean from typical viewing distances, while inclusions may be visible under magnification for those who examine the stone closely.

The gem is inherently versatile and the dimensions and cut make it appropriate for a wide range of mounting styles, from refined solitaires to contemporary bezel settings, from halo rings that emphasize the central color to pendant and earring designs that allow light to play across the mixed cut facets. The bluish green hue adapts well to different metal choices, appearing warmer against yellow and rose gold, and maintaining crisp contrast against white gold and platinum, enabling coherent styling for both casual and formal wardrobes. For everyday pieces such as rings and bracelets, the robust hardness and natural clarity support durable wear, and for formal pieces such as dinners or gala events, the intense color and precise polish deliver the presence expected of a refined gemstone. For care, routine cleaning with warm soapy water and a soft brush restores brilliance, and for any ultrasonic or steam cleaning considerations the buyer should consult The Natural Sapphire Company for recommendations specific to this untreated stone. The Natural Sapphire Company provides detailed documentation of weight, dimensions, cut style, clarity observation, color description, polish grade, treatment status, and origin, and the company is available to answer technical questions or assist with custom mounting options that showcase the gem in settings suited to both everyday use and special occasions.
