3.10 Ct. Bluish Green Sapphire from Madagascar

This sapphire is a transparent, bluish green oval weighing 3.10 carats, measuring 9.12 by 7.43 by 5.41 millimeters, originating from Madagascar. The gem is faceted in a mixed brilliant style, and it is evaluated as eye clean at standard viewing distance. Color intensity is described as intense, and the surface presentation is finished to an excellent polish. There has been no enhancement performed on this stone, the color and clarity are natural, and the combination of transparency and clean eye appearance allows the stone to present its full optical character without treatment. The Natural Sapphire Company presents this gem with clear provenance and technical details to support appraisal and design decisions.

The geometric faceting of this oval sapphire is arranged to maximize light play through a deliberate interplay between crown and pavilion facets. The mixed brilliant approach places a series of brilliant style facets on the crown to enhance flash and scintillation, while the pavilion employs stepped facets to produce deep mirror like reflections and controlled light return. The oval outline concentrates these effects along the long axis, creating linear flashes and a lively pattern of bright and dark areas when the stone moves. Facet junctions, symmetry and proportional placement of each facet plane are calibrated to promote internal reflection rather than light leakage, and the result is both strong brilliance and a lively scintillation that complements the gem s intense bluish green hue. The precise geometry also supports even color distribution, avoiding windowing and enabling the face up appearance to read as a saturated, vivid color with dynamic internal sparkle.

The proportions of this stone contribute materially to its optical performance. With a depth that measures 5.41 millimeters relative to the oval dimensions given, the pavilion depth and crown height are balanced to provide substantial internal light return while preserving a generous face up area. This balance produces a presence on the finger that is both elegant and visually impactful for a three carat plus oval. The eye clean clarity grade removes potential obstruction to light flow, so the intricate facet network can operate without interruption from visible inclusions. Excellent polish further ensures that each facet plane acts as a clean refracting and reflecting surface, increasing apparent brightness and crispness of facet reflections. In addition, the mixed brilliant geometry interacts with the stone s inherent pleochroic tendencies, so slight shifts in viewing angle reveal subtle variations between blue green and green blue components of color, a characteristic that lends visual complexity without compromising overall saturation.

Practical considerations for setting and use follow directly from the gem s attributes. Sapphire is a hard and durable gemstone suitable for everyday wear, and this oval 3.10 carat example is well suited to center stone settings where its mixed brilliant faceting and intense color can be shown to advantage. The oval shape lengthens the visual line of a finger while the measured proportions maintain a balanced profile for bezel, prong or hybrid mounting types that preserve light entry through the crown. Because this stone carries no enhancement, handling and design decisions can be made with the assurance that its color and clarity are natural. The Natural Sapphire Company supplies detailed measurements and origin information to support responsible design and valuation, and the documented attributes of this sapphire, including its geometric faceting, eye clean clarity, intense natural color, and excellent polish, together explain its strong light performance and suitability for precision jewelry settings.
