1.64 Ct. Green Sapphire from Madagascar

This transparent 1.64 carat cushion shape green sapphire measures 7.21 x 5.96 x 4.42 mm, and it is faceted with a mixed brilliant cut to balance spectral return and depth of color. Clarity is described as very very slightly included, evaluated at eye level, which indicates minimal internal features that do not detract from the gem at typical viewing distances. The stone exhibits intense color intensity with a green hue that shows subtle directional variation, and it carries an excellent polish that enhances surface reflectivity and facet definition. The sapphire is natural, with no enhancement, and it originates from Madagascar, a source known for producing well colored corundum. The combination of weight, proportions, and finish make this gem well suited for use as a solitaire center or as a refined accent, where its transparency and cut will allow it to read consistently under varied lighting conditions.

When considered against other gemstones in its category, this Madagascar green sapphire demonstrates the characteristic high light return and crisp facet contrast associated with corundum, attributable to sapphires having a higher refractive index than many green gemstones. Compared to beryl varieties such as emerald, which have lower refractive indices and typically a softer, more diffused luster, this sapphire presents stronger scintillation and a more lively play of light. Relative to tourmaline and peridot, which can display good color but generally produce less intense sparkle, the sapphire offers a firmer, more adamantine brilliance, particularly when cut with mixed brilliant faceting that emphasizes both crown flash and pavilion return. The stone also differs from step cut green gems, which favor color depth over brilliance, by delivering a balance of vibrant hue and dynamic reflectivity. In keeping with The Natural Sapphire Company standards, this sapphire’s combination of clarity, intense color, excellent polish, and unenhanced provenance yields a gemstone with notable visual presence and enduring optical performance.
