1.17 Ct. Green Sapphire from Madagascar

This transparent 1.17 carat radiant shape green sapphire presents a rare combination of classical proportion and natural character, offered by The Natural Sapphire Company. The stone measures 6.56 x 4.84 x 3.92 mm, and carries a precise radiant cut that maximizes table size while preserving faceted brilliance. Clarity is graded as slightly included at eye level, and the gem exhibits medium color intensity with a balanced green hue. The polish on the pavilion and crown is graded excellent, resulting in crisp facet junctions and clean reflections across the table and crown facets. Importantly for discerning buyers, this sapphire has not undergone any enhancement, and its origin is Madagascar, a source known for producing a wide spectrum of natural sapphires with interesting tone and saturation combinations. These technical details are intended to provide an accurate baseline for evaluation, and they reflect The Natural Sapphire Company commitment to full disclosure and gemological transparency.

From a gemological perspective, the radiant cut of this green sapphire is especially relevant to both appearance and value. The radiant cut blends the step like clarity of an emerald inspired outline with the brilliance of a mixed faceting scheme, which helps to disperse light and reduce the visual impact of inclusions when compared to a flat table or a shallow cut. With a clarity grade of slightly included at eye level, internal features are present but not intrusive, and they can contribute to the stone character while maintaining good durability. The excellent polish enhances light return from each facet, increasing apparent brightness and making the stone perform well in settings that allow light to enter from multiple angles. For the educated buyer, these attributes mean the sapphire offers a harmonious balance of beauty and natural authenticity, with the absence of enhancement contributing to long term rarity and potential collector appeal.

Color and origin are central to the appraisal of this sapphire, and Madagascar provenance plays a meaningful role in its story. Madagascar sapphires are known for a wide distribution of hues, and this example displays a medium intensity green that is well suited to both classic and contemporary jewelry design. Medium intensity denotes a saturation level that is neither weak nor overpowering, which allows the gem to read as a true green under neutral lighting while retaining depth when viewed in stronger light. The green coloration in natural corundum is typically influenced by trace iron, and the specific balance of hue and tone here yields a versatile green that complements yellow metals and white metals alike. Origin documentation and accurate grading are valued by collectors and professional gem buyers, and The Natural Sapphire Company provides clear provenance to support both aesthetic appreciation and investment considerations.

How the gem appears under different lighting conditions is an important practical consideration for purchase. In natural daylight with a neutral color temperature, the stone will present its true medium green, with even color distribution across the table and well defined facet reflections due to the excellent polish. Under warm incandescent lighting, the stone may appear slightly warmer, with subtle deepening of tone and increased contrast between facet planes, producing a richer looking green that can feel almost teal depending on surrounding colors. Under cool LED or fluorescent lighting, the stone tends to maintain its green character but may display increased scintillation along the pavilion facets, a consequence of the radiant cut geometry that directs light back through the crown. Pointed light sources such as a jeweler lamp or direct sun can reveal the internal features that define the slightly included clarity grade, but these inclusions are generally not distracting in everyday wear, and they contribute to the gem authenticity that many connoisseurs seek. When set as a ring, center stone reflections will be influenced by metal color and setting style, with open prong settings allowing the most lively interaction with ambient light, and bezel settings providing a more controlled, depth rich appearance. For care, gentle cleaning with warm soapy water and a soft brush is recommended to preserve the excellent polish and keep facet junctions clear, and routine inspections of the mounting will protect the gem and ensure optimal light performance.
