2.04 Ct. Greenish Blue Sapphire from Madagascar

This transparent 2.04 carat cushion shape greenish blue sapphire measures 7.28 x 6.62 x 4.75 mm, and presents a depth that corresponds to approximately sixty eight percent of its average diameter, a proportion that favors balanced light return and saturation. The stone is cut in a mixed brilliant style, which combines a faceted brilliant crown with a modified pavilion geometry, and this approach was selected to retain rich body color while maximizing scintillation. Clarity is graded as very slightly included, evaluated at eye level, the inclusions are minor and do not detract from optical performance. Color intensity is described as intense, and the sapphire displays excellent polish across facet junctions, contributing to sharp reflection boundaries and strong contrast. This specimen has undergone standard heat treatment to optimize hue and tone, and originates from Madagascar, a source known for producing sapphires with lively teal and greenish blue tendencies. The Natural Sapphire Company presents this gem with the technical provenance and finishing details that informed buyers expect.

From a faceting standpoint, the mixed brilliant configuration on this cushion takes advantage of a broad table and relatively low to medium crown height, generating large flashes and a spread of brilliant flashes as the stone is tilted. The pavilion shows stepped facet planes that are proportioned to control light leakage and to reduce windowing, an effect where the center appears washed out under strong light. Excellent polish enhances the internal reflection efficiency, the facet planes act as crisp mirrors, and the facet junctions are executed to tight tolerances so that return light is coherent rather than diffused. The result is a dynamic pattern of contrast and bright flashes, with scintillation characterized by larger, defined flashes rather than the fine pinpoint scintillation seen in high index gemstones. Birefringence in corundum is low, and this sapphire benefits from that optical steadiness, presenting stable color saturation across changing angles rather than dramatic color splitting, though pleochroism toward slightly greener and bluer axes is present when viewed with polarized light.

Color behavior for this gem is technical and nuanced, it sits in the greenish blue field with a strong blue bias under neutral artificial lighting, while under daylight it reveals a more balanced teal appearance. The intense color intensity enhances perceived depth, and because the pavilion depth is robust, the stone avoids excessive light leakage that can desaturate color. Heat treatment has been applied to stabilize and deepen the chromophore distribution within the crystal lattice, reducing uneven zoning and improving overall translucency. Compared to Sri Lankan sapphires that frequently display lighter, more vivid cornflower to sky blue tones, this Madagascar example delivers greater body color and saturation. Compared to classic Kashmir material, which is prized for a velvety, diffused reflection due to historical silk like inclusions, this sapphire provides crisper facet reflections and more distinct scintillation. Relative to Australian and Thai sourced sapphires that can trend darker and more inky, the present stone maintains livelier light return and clearer internal reflection, making it well suited to settings that allow top light ingress.

When comparing reflective qualities within the sapphire category, the mixed brilliant cushion shows advantages in contrast and defined light patterning versus step cut or deep mixed cuts that tend to emphasize color at the expense of brilliance. A well executed mixed brilliant cut in corundum leverages the material refractive index which is moderate for a gemstone, producing strong luster without the high dispersion associated with gemstones like diamond. Compared to spinel, which has slightly lower refractive index and typically returns light in broader, less scintillating flashes, this sapphire exhibits tighter, more energetic flashes due to facet arrangement and polish quality. Against tourmaline and aquamarine from the same color family, the sapphire maintains superior luster and durability, its hardness and refractive properties giving it a livelier face up appearance and greater resistance to wear. For collectors and designers considering optical performance, this Madagascar sapphire from The Natural Sapphire Company offers a technical balance of intense body color, controlled depth percent, precise faceting strategy, and excellent polish, yielding a gemstone that presents strong, well defined reflections and sustained color saturation in a wearable and versatile 2.04 carat cushion form.
