6.11 Ct. Bluish Green Sapphire from Madagascar

Beneath the mossed slopes and forested highlands of Madagascar, where ancient rivers have traced slow routes through time, a crystalline secret took shape in patient silence, trapped within the earth for millions of years. Miners who know these lands by the color of morning light and the taste of rain follow clues in alluvial beds, and in rare seasons they uncover rough crystals that glow with unusual depth. This bluish green sapphire began its life in that old silence, forming under conditions that favored a fusion of blue and green tones, a balance that is uncommon and deeply evocative. The journey from its rough state to a polished gem carried with it the stories of the ground that birthed it, and the human hands that recognized its promise, a promise that we at The Natural Sapphire Company are honored to bring forward.

At the heart of this narrative is a single gem whose specifications mark it as exceptional, among the rare offerings you will find. We present a transparent 6.11 carat heart shape bluish green sapphire, with exact dimensions of 10.99 x 11.24 x 6.98 mm. The cutter chose a mixed brilliant cut to maximize both scintillation and depth, a decision that highlights the intense color intensity while preserving weight. Clarity is graded as slightly included when evaluated at eye level, a characteristic that often confirms natural origin and lends a fingerprint like proof of its history. The stone has undergone heat treatment, a common enhancement that deepens hue and clarifies tone, and it receives an excellent polish that allows light to dance freely across its facets. When compared to more common sapphires in either pure blue or pure green, this bluish green hue is far rarer, and finding it in a heart shape at this scale is even more unusual, making this gem a standout in both color and size among similar options.

The transformation from a piece of rough crystal to this precise heart involved careful artistry and choices at every stage. Skilled cutters assessed internal features and color zoning to determine the orientation that would reveal the stone at its best, then executed the mixed brilliant plan to create a play of light that reveals flashes of teal, deep turquoise, and forest green as the gem moves. Heart shapes demand symmetry and tender judgment, because too much material removed in pursuit of perfection can sacrifice weight and impact, while too little refinement can leave the silhouette heavy and indistinct. The cutter of this sapphire struck a rare balance, retaining the generous 6.11 carat presence while achieving crisp lobes and a defined cleft that reads effortlessly as a heart, a form that carries timeless symbolism of love, devotion, and affection across cultures. The slightly included clarity gives character rather than compromise, a reminder that this is a product of nature, with natural inclusions that testify to geological formation and authenticity.

Wearing a gem with this lineage is to carry a fragment of the landscape where it formed, and to participate in a long human tradition of honoring rare color and elegant form. For collectors and brides, for those selecting an engagement piece, and for anyone seeking an unusual center stone, this sapphire offers a conversation between rarity and wearability, between an intense bluish green presence and a versatile silhouette that adapts to many setting styles. The images show the proportion and scale, including a styling example on a hand for reference, and the visual presence there helps convey how the heart shape reads in relation to gesture and movement. The Natural Sapphire Company stands ready to assist with setting recommendations, bespoke design services, and further information about the gem provenance and care. This heart shaped bluish green sapphire is not only a striking aesthetic choice, it is a rare natural object with a clear story from Madagascar, and it is offered as an heirloom piece that can be passed down, admired, and loved for generations.
