2.20 Ct. Greenish Blue Sapphire from Madagascar

One transparent 2.20 carat oval greenish blue sapphire is presented with precise dimensions of 8.52 x 6.81 x 4.87 mm, a mixed brilliant cut and an overall face up presence that balances depth and sparkle. The clarity grade is slightly included, evaluated at eye level, a characteristic that affirms natural growth patterns while preserving good transparency for light return. Color is described as vivid in intensity, offering saturated blue and green tones that shift with viewing angle and light source. The polish has been graded excellent, providing crisp facet junctions and a smooth surface that enhances luster. Enhancement is disclosed as heat treated, a standard and stable treatment that improves color uniformity without compromising the structural integrity of corundum. The origin of the sapphire is Madagascar, a source known for fine colored stones with a range of blue and teal hues, and this provenance contributes to the gemological profile that accompanies the material.

The mixed brilliant cut integrates pavilion facets that extend light return with elegant crown facets for scintillation, creating an appealing balance between sparkle and color saturation. In this oval, the combination of cut proportions and excellent polish yields lively facet reflections and controlled windowing, allowing the vivid greenish blue color to appear both deep and vibrant when set. Slight inclusions are present, observable at eye level, and these inclusions are typical of natural sapphires from Madagascar, offering confirmation of origin and natural formation. The gem displays good transparency and a pleasing face up size for its carat weight, making it versatile for a variety of jewelry settings where the interplay of color and light is desired. Photographic references show the stone on a hand, demonstrating scale and the way the color interacts with skin tones, which can assist in final design decisions.

On the Mohs hardness scale, sapphire is a corundum variety with a hardness of 9, ranking just below diamond, which is 10, and above commonly used gemstones such as topaz at 8, and quartz at 7. This high hardness makes sapphire one of the most durable colored gemstones for daily wear, suitable for engagement rings and bracelets with proper mounting. The 9 on the Mohs scale indicates strong resistance to scratching from most materials encountered in everyday life, however care should still be taken to avoid knocks against harder materials and sharp impacts that can cause chips. Routine wearers will find this sapphire robust, yet best practice includes periodic inspection of the setting, avoiding exposure to harsh chemicals, and cleaning with warm, soapy water and a soft brush to preserve polish and luster. Professional cleaning and appraisal are recommended when altering settings or after long periods of wear to ensure prongs and other mounting elements remain secure.

For those commissioning a setting, the dimensions 8.52 x 6.81 x 4.87 mm and the 2.20 carat weight offer predictable planning for bezel, prong, or halo styles, with considerations for the stone depth and table size to optimize light return. With appropriate care and periodic professional maintenance, this Madagascar sapphire will maintain its structural integrity and visual appeal, making it a durable and attractive choice for long term wear.
