1.39 Ct. Green Sapphire from Tanzania

This transparent oval green sapphire weighs 1.39 carats, and measures 7.45 x 5.65 x 3.61 mm, a size and proportion that offers a beautiful visual spread for an elegant ring or pendant. The gem is cut in a mixed brilliant style, a choice that balances scintillation with color saturation by combining brilliant facets and step facets to best display the stone under varied lighting. Clarity has been evaluated as slightly included at eye level, an honest and useful grading for the informed buyer, and the polish is excellent, indicating that the cutter finished the facets with care to maximize sparkle and light return. Color intensity is described as intense, and the green hue is clean and appealing without visible color zoning in most viewing angles. Importantly this sapphire is unenhanced, no heat or other treatments have been applied, and its origin is Tanzania, a region known for producing attractive and characterful green corundum specimens. When discussing provenance and technical details, The Natural Sapphire Company ensures that you are receiving a full picture of what makes this sapphire both beautiful and technically notable.

In gemological terms the combination of attributes here creates a compelling profile for a connoisseur. The slightly included clarity grade means that the stone shows minor internal characteristics when viewed carefully, characteristics that are typical in natural corundum and that can often be used as internal fingerprints of origin. These inclusions do not materially affect durability, and they are not distracting in the hand or once the gem is set. The mixed brilliant cut is especially effective in an oval outline, where the length to width ratio and the pavilion geometry control both the amount of light returned and the way color is distributed across the table. At 7.45 x 5.65 x 3.61 mm, this sapphire has enough depth to display its intense green color without appearing dark under normal lighting, and the excellent polish contributes to crisp facet junctions and lively reflection. For buyers who evaluate gems with a technical eye, these cutting and finishing qualities are key determinants of long term desirability and performance when worn.

The Tanzanian origin adds an important layer of value for an educated buyer, because regional characteristics influence color palette and market perception. Tanzania has produced a variety of green and teal sapphires that are appreciated for their nuanced tones and natural beauty. Green sapphires acquire their color from trace elements, commonly iron and in some cases a combination of iron and titanium, and the precise balance of these elements is what produces the range from soft meadow greens to deeper forest tones. Because many sapphires in the market are heat treated to improve color and clarity, an untreated green sapphire from a recognized origin commands a premium. This piece being completely unenhanced increases its rarity and investment potential, while its hardness of nine on the Mohs scale means it is well suited to everyday jewelry when placed in a protective and thoughtful setting. For longevity and to showcase the color, complementary settings in yellow gold will warm the green, while white metals such as platinum or white gold will present a cooler, more contemporary aesthetic.

Owning this sapphire is an investment in beauty and craftsmanship, and a purchase that can be appreciated on both aesthetic and technical grounds. From an aesthetic perspective the stone offers an intense, transparent green that performs well under different lighting conditions, paired with a cut and polish that deliver brightness and life. From a craftsmanship perspective the choice to leave the stone unenhanced, and the skill applied to the mixed brilliant cutting and excellent polishing, ensure that the gem will age gracefully and remain desirable to future collectors or buyers.
