1.09 Ct. Bluish Green Sapphire from Madagascar

This transparent bluish green sapphire presented by The Natural Sapphire Company weighs 1.09 carats and is cut in an asscher octagon shape with precise dimensions of 5.72 x 5.52 x 3.47 mm. The cutting style is faceted, with an asscher cut executed to emphasize step facet geometry and internal symmetry. Clarity has been evaluated at eye level as very very slightly included, offering exceptional visual purity without the need for magnification to appreciate its internal cleanliness. Color intensity is described as intense, yielding vivid bluish green saturation that remains stable from the crown under a variety of lighting conditions. The gem has not undergone any enhancement, and its polish is graded excellent, reflecting a commitment to natural material and meticulous finish.

The asscher cut is central to the stone s optical character and its distinctive sparkle. This cut uses a series of concentric step facets on both the crown and pavilion that create a layered optical effect often described as a hall of mirrors, an effect that is especially pronounced in stones with the transparency and clarity of this sapphire. The square to octagonal outline produced by the asscher arrangement of facets concentrates light into broad reflective planes rather than the pinpoint scintillation typical of brilliant cuts. In practice this means that the light play in this sapphire appears as luminous flashes and depth rich reflections that shift with movement, producing a depth and coherence to the sparkle that is visually different and in many settings preferred to the rapid twinkle of brilliant faceting. The proportions of this example are well balanced, with the measured depth of 3.47 mm corresponding to a depth percentage of approximately 61.7 percent when referenced to the average of the girdle widths, a proportion that supports generous light return and allows the step facets to act in concert to reinforce the stone s internal brightness.

The material properties of corundum contribute materially to the quality of the optical performance you observe. Sapphires have a refractive index in the high range for gemstones, which improves light refraction and contributes to lively return of light through the crown, while the low dispersion of corundum preserves color purity so that the bluish green hue presents without the spectral separation that can dilute a single tone. This sapphire s hard and durable nature ensures that the precise facet junctions and the excellent polish remain stable through wear, maintaining the clarity of reflections and the crispness of facet edges that underpin the asscher s characteristic mirrorlike flashes. Pleochroic tendencies in sapphire can cause subtle tonal shifts as the stone is rotated, and in this material those shifts enhance the perception of dimensionality without masking the intense color or interrupting the steady, layered reflections that the cut produces.

Ultimately the combination of inherent material properties, precise asscher faceting, and uncompromised finishing produces a sparkle and visual depth that is distinct within the range of sapphire cuts. The Natural Sapphire Company presents this 1.09 carat, 5.72 x 5.52 x 3.47 mm, asscher faceted sapphire as an example of how geometry and material interact to create a refined optical signature. Originating from Madagascar, unenhanced, and offered with very very slight inclusions at eye level and excellent polish, the gem demonstrates how a carefully executed asscher cut can emphasize brilliance as controlled planes of reflected light, delivering an appearance that is both elegant and unmistakable in its clarity and intensity.
