0.47 Ct. Bluish Green Sapphire from Madagascar

This description concerns a single, transparent sapphire, weighing 0.47 carat, cut in an emerald shape, and presenting a bluish green hue. The stone measures 4.92 by 4.09 by 2.57 millimeters, and it carries a clarity grade assessed as very very slightly included at eye level. The color intensity is classified as intense, and the finish reflects an excellent polish. The sapphire has been heat treated, and its documented origin is Madagascar. These objective attributes define the gem at a technical level, and they set expectations for optical performance, durability, and potential use in fine jewelry.

The emerald cut emphasizes the stone s color plane through broad, flat facets, and in this example the step cut geometry produces a controlled, even display of the bluish green body color. The transparency and the very very slightly included clarity allow light to pass with minimal internal disruption, so color is presented with depth rather than scattered brilliance. The excellent polish sharpens facet junctions and contributes to clean reflection and contrast along the step facets, permitting the hue to shift subtly with viewing angle and light source. The modest dimensions and precise cutting make this sapphire particularly well suited for settings that prioritize color and clarity over flashy sparkle, for example a solitaire ring with a low profile, a three stone design as a secondary gem, or a refined pendant where the emerald cut can be appreciated from the face view.

When compared to historically famous gemstones, this sapphire offers a distinct set of merits rather than aiming to replicate any single iconic example. By contrast with classic Kashmir sapphires, which are celebrated for their velvety cornflower blue and larger sizes, this Madagascan stone presents a bluish green tone and a step cut that focuses attention on hue and clarity rather than on saturation alone. Unlike the Logan Sapphire, a large deep blue cabochon known for weight and provenance, this gem s strength lies in precision cutting and transparent, intense color in a small format. In comparison with star sapphires such as the Star of India, which rely on asterism caused by needle inclusions, this emerald cut specimen deliberately minimizes inclusions to prioritize clean optical fields, so it offers a different visual language, one of refined planes and color depth. The heat treatment applied to this sapphire is consistent with standard enhancement practices used historically to stabilize and enhance color in corundum, and disclosure of this treatment aligns with the transparent approach favored by collectors and experienced gem buyers.

For practical selection and care considerations, the stone s balanced proportions and excellent polish support enduring use in jewelry that sees regular wear, provided standard corundum care is observed. Setting choices that protect the girdle and corners, such as bezel or protective prong designs, will preserve the cutter s geometry and reduce the risk of damage. The Natural Sapphire Company provides full disclosure of origin and enhancement, and this sapphire is a representative example of Madagascan material that offers intense color in a compact, accurately cut parcel. For clients seeking a gem that conveys measured elegance, historical reference, and gemological clarity, this bluish green emerald cut sapphire represents a considered choice that reflects both natural character and skilled lapidary work.
