4.09 Ct. Bluish Green Sapphire from Tanzania

There is a quiet ocean held within this stone, a gentle world of blue and green that catches and keeps the light, a memory of Tanzanian horizons folded into crystal. This is a C.Dunaigre certified Blue Green sapphire, a 4.09 carat oval shape bluish green gem, its dimensions are 10.19 x 7.75 x 5.69 mm, a poised and generous presence that sits comfortably on the hand, the neck, the heart. Cut in a mixed brilliant style, the pavilion and crown are balanced to coax scintillation and flash from every angle, while an excellent polish makes every facet a mirror for sunlight and candlelight alike. The color is vivid, alive with depth and clarity, and though the clarity grade is very slightly included evaluated at eye level, those small signatures of origin only deepen the sense of authenticity, like the fingerprints of the earth itself. There has been no enhancement, the tone and saturation are untouched, a natural song of color that begins in Tanzania and continues through every setting we might imagine, and The Natural Sapphire Company offers this gem with the quiet assurance of certified provenance.

Beyond its beauty, the sapphire is a stone of steadfastness, its nature suited to the rhythms of daily life, and to the rituals that mark love and commitment. With a hardness of nine on the Mohs scale, this sapphire resists scratching from nearly every material it will meet, all but diamond, and that resilience means the polish will remain bright, the facets will continue to sing, even after years of wear. Toughness is another gift here, the crystal structure of corundum tends to resist breaks and chips, and with the very slight inclusions evaluated at eye level, there is no structural compromise that would make this gem vulnerable to gentle daily knocks. Because the stone is natural and untreated, its color will not fade with exposure to light, nor will it alter with ordinary chemicals found in soaps and lotions, and the excellent polish and mixed brilliant cut enhance the light return so that the gem remains lively under office lights, sunlight, and the softer lamps of evening. For everyday settings, classic prongs lend a light, airy display, while a bezel offers the utmost protection, embracing the oval form and safeguarding the girdle, choices that honor both the romance of the stone and the practical need for durability.

Care for this sapphire is straightforward, which is part of its appeal for a life that includes both adventure and quiet moments. Routine cleaning in warm soapy water and a soft brush will restore the sparkle in minutes, and because there has been no heat or other enhancement, this sapphire is generally safe for ultrasonic and steam cleaning, a practical benefit when you wish to return it to full brilliance, though we always recommend a check of the setting before subjecting any mounted gem to strong mechanical cleaning. Avoid deliberate hard impacts, as with any fine jewel, and inspect prongs periodically to ensure a secure embrace. With sensible care, this Tanzanian beauty will pass seasons and styles, an heirloom in the making, a reliable companion for the everyday and the extraordinary. The mixed brilliant cut continues to perform day after day, scattering flecks of light in the smallest movements, turning simple gestures into small ceremonies of radiance.

Imagine an engagement ring that seems to hold a promise of sea and forest, a pendant that breathes with every step, a piece that will age without losing its voice, gaining stories as its surface catches the life around it. This 4.09 carat C.Dunaigre certified Blue Green sapphire invites you to design a setting that speaks to your story, a bezel to shelter, a halo to heighten, a solitaire to declare. Its Tanzanian origin is part of its poetry, a provenance that connects you to a landscape and a lineage, and The Natural Sapphire Company stands behind its authenticity and its ethical sourcing, offering the knowledge and confidence you need as you choose a gem for daily devotion. If you seek a stone that combines the romance of vivid color with the practical strength required for everyday wear, this bluish green oval is a rare balance of heart and habit, a jewel that promises endurance, and that will continue to reflect the light of your life for decades to come.
