3.11 Ct. Greenish Blue Sapphire from Tanzania

This 3.11 carat cushion shape greenish blue sapphire is a true conversation jewel, with precise dimensions of 7.56 by 7.33 by 5.88 mm, a mixed brilliant cut, intense color intensity, and an excellent polish. Sourced from Tanzania and offered by The Natural Sapphire Company, this stone stands apart from the more common heat treated and heavily modified sapphires that dominate the market. Many sellers rely on color enhancement to produce lively blues, and some lower cost options are synthetic or heavily altered to mimic desirable tones. By contrast this sapphire is without enhancement, preserving the natural chemistry and origin driven hue that only a genuine Tanzanian crystal can present. The mixed brilliant cutting style yields dynamic reflections and scintillation that keep the stone lively under all lighting conditions, and the cushion silhouette balances classic elegance with contemporary appeal. At eye level the clarity is graded slightly included, which in a natural, untreated sapphire at this size serves as an explicit marker of authenticity, and the excellent polish ensures the table and crown facets catch light with luxurious clarity.

When customers compare this sapphire to other market options, the difference is instantly tangible. Many commercially available sapphires in similar sizes will sacrifice color saturation for clarity through heat treatment, or will present as overly uniform and glassy if grown in a lab. Those stones often lack the depth and complexity of tone that a natural, intense greenish blue sapphire from Tanzania shows, and they rarely combine strong color with a cushion cut that has been optimized for brilliance. The slightly included clarity in this stone actually enhances its personality, creating microscopic pinpoints and character that refract light in a way that is recognizably natural, rather than sterile. The 3.11 carat weight occupies a sweet spot for wearable luxury, larger than many mass market stones yet still comfortable for everyday rings and pendants, and the 5.88 mm depth provides a satisfying presence without feeling bulky. From a value perspective, untreated sapphires with intense coloration and verified origin command a premium for good reason, they are rarer and retain long term appreciation. Buyers who prioritize authenticity and provenance will find that this stone outperforms more common, altered sapphires on both aesthetic and investment grounds.

This sapphire makes a striking gift for someone special because it combines visual drama with meaningful rarity. The deep greenish blue hue reads differently depending on ambient light, shifting from ocean teal to deep forest blue, which gives the wearer a small daily surprise and a jewel that seems to evolve with them. In a custom ring setting, the cushion outline offers generous table size to showcase the mixed brilliant cut, while the intense color will contrast beautifully against both yellow and white precious metals, providing flexibility in design choices. Unlike trend pieces that may feel contemporary for a season, a natural Tanzanian sapphire feels timeless, suitable for milestone celebrations, anniversaries, or as a personalized engagement gem for a discerning partner who values individuality over convention. The presence of natural inclusions tells a story of earth formed processes, making the stone not just beautiful, but authentic, a tangible narrative of its journey from mine to master cutter. At The Natural Sapphire Company we stand behind the gem with documentation of origin and treatment status, and our commitment to ethical sourcing and expert gemological evaluation ensures that the gift will be received with confidence as well as wonder.

Choosing this 3.11 carat cushion greenish blue sapphire from The Natural Sapphire Company offers a clear advantage over mass market alternatives, because it is rare to find such intense, untreated color in a well proportioned cushion cut at this scale. The mixed brilliant cutting enhances brilliance in a way that many step cut sapphires cannot match, and the excellent polish guarantees an immediate optical appeal the moment it is held up to the light. If you desire a memorable, striking gift that combines visual impact with geological authenticity and long term value, this Tanzanian sapphire represents a superior option. Our specialists can assist with setting suggestions, appraisal documentation, and bespoke design services to transform this exceptional stone into a permanently cherished heirloom.
