6.58 Ct. Bluish Green Sapphire from Ethiopia

Sapphires have been treasured for millennia as symbols of wisdom, protection, and enduring love, and this beautiful Ethiopian treasure embodies that long tradition while speaking to a modern sensibility. Certified by C. Dunaigre, this transparent blue green sapphire weighs 6.58 carats, and it is cut into a classic round shape measuring 11.45 by 11.26 by 7.11 millimeters, with a mixed brilliant cut that brings contemporary scintillation to a venerable form. The stone has been graded as very very slightly included at eye level, a clarity that allows the gem to read as clean and luminous in hand, and an excellent polish further enhances its reflective life. Heat treatment has been applied, a time honored and widely accepted enhancement that intensifies and stabilizes color, and the origin is Ethiopia, a source that in recent years has supplied some of the most expressive and richly hued sapphires to the world market. At The Natural Sapphire Company we pair the assurance of independent certification with decades of experience selecting stones that will endure as family heirlooms, and this piece is an eloquent example of nature and craftsmanship in harmony.

What makes this sapphire particularly compelling is its bluish green hue and its intense color intensity, a depth of tone that sits beautifully between oceanic teal and deep sea green, with a blue core that gives the gem a jewel like coolness without tipping into the purely blue territory of some other famous sources. Compared to classic Ceylon sapphires from Sri Lanka, which often show a lighter, brighter cornflower to royal blue, this Ethiopian stone leans greener and darker, offering a more mysterious and woody character. Against the legendary velvety blues of Kashmir, prized for their soft diffusion and royal saturation, this stone reads as clearer edged and more vivacious, its mixed brilliant cut sharpening reflections where Kashmir pieces tend to glow from within. Against Burmese or Myanmar blues, which often register as intense, inky royal blue, the Ethiopian sapphire reveals a noticeable green component that softens the strict blue and contributes to a cooler, more maritime personality. When placed alongside Australian sapphires, which can present as inky, dark teal to almost black blue, this gem remains brighter and more brilliant, its facets returning livelier flashes of blue and green. American Montana sapphires have long been admired for their blue green and teal expressions, and this Ethiopian example is in conversation with that palette, but with higher saturation and a round mixed brilliant cut that maximizes fiery return. Madagascan sapphires can present a range of vivid blues and greens as well, and here the Ethiopian stone stakes its claim by balancing a deep, oceanic tone with lively internal brightness, a union of emerald like green and sapphire blue that reads as elegant and rare.

For someone who values lineage and permanence, the round brilliant silhouette of this 6.58 carat gem will translate effortlessly into a timeless engagement ring, a signet style heirloom, or a centerpiece pendant destined for generation to generation. The mixed brilliant cut gives modern sparkle while the round form speaks a classical language that has resonated through centuries, from royal treasuries to contemporary ateliers, ensuring that set in yellow gold the green warmth will glow, and set in platinum or white gold the blue steel aspect will sing. At The Natural Sapphire Company we take special care to present stones whose physical virtues are matched by provenance and ethical clarity, and this Ethiopian sapphire carries with it an origin story that ties contemporary craftsmanship back to the ancient reverence for colored stones. Heat treatment, noted on the certificate, is a stable enhancement widely practiced in the trade to bring out the stone's optimal hue and should be considered a standard means of enhancing longevity and visual impact, rather than a detractor. If you seek a gem that bridges legendary sapphire traditions with a distinctive, maritime blue green hue, this certified Ethiopian sapphire offers a rare combination of saturated color, fine clarity, and classical form that will be cherished now and passed on as an emblem of taste and continuity.
