0.79 Ct. Greenish Blue Sapphire from Madagascar

This 0.79 carat pear shape sapphire presents as a compact yet commanding gemstone, measuring 6.87 by 4.55 by 3.39 mm, with a mixed brilliant cut that has been executed to exacting standards. The cutter has paired a brilliant style crown with a faceted pavilion, producing a controlled interplay between broad flash and fine scintillation, the result being a lively, directional brilliance that reads well in both diffuse and direct light. Facet junctions are sharp and the outline displays precise symmetry for a pear form, the excellent polish enhancing contrast between table and pavilion reflections, and minimizing surface diffusion so that internal light return is optimized. With a clarity grade of very very slightly included, evaluated at eye level, the stone is essentially eye clean, the minute inclusions positioned and oriented so as not to disrupt overall light performance or to create discernible windowing under normal viewing conditions.

The color is a refined greenish blue, assessed as medium intense in saturation, with a pleasing balance between chroma and tone that maintains strong color presence without appearing overly dark in smaller mounting sizes. The sapphire exhibits subtle pleochroic behavior typical of corundum, showing a shift between blue and green hues when rotated, which adds depth and dynamism to the gem when set. Origin is Madagascar, a source known for producing complex teal and blue green material, and the stone has been heat treated, a standard enhancement that stabilizes and intensifies color while improving transparency. For collectors and designers seeking a standout center gem, this pear shaped sapphire is ideally suited to bezel or open halo settings that allow light to enter the pavilion and display its mixed cutting geometry, making it a natural focal point in either a bespoke ring or pendant. The Natural Sapphire Company presents this gem as an example of meticulous cutting and finishing, a stone whose combination of precise proportions, excellent polish, and medium intense greenish blue color make it a distinguished centerpiece for any serious collection.
