1.09 Ct. Bluish Green Sapphire from Madagascar

Millions of years ago, deep within the earth beneath the ancient crust of Madagascar, this sapphire began its slow and deliberate transformation. Subjected to intense heat and pressure during regional metamorphism and tectonic uplift, aluminum rich host rocks recrystallized and concentrated into corundum, the mineral form of sapphire. Silicate fluids and residual melts carried trace elements into growing crystals, and small quantities of iron and titanium influenced the wavelength of light absorbed, yielding the bluish green hue seen today. Over geological time, cycles of burial and erosion liberated crystals from their primary matrix, and river systems transported and sorted them, concentrating gem quality material into secondary alluvial deposits. The result is a gemstone that records a complex history of crystallization, alteration, and transport, a stone that is both a mineralogical product of deep time and a witness to dynamic surface processes.

The finished sapphire presented by The Natural Sapphire Company is a transparent, faceted radiant shape weighing 1.09 carat, with dimensions of 5.69 x 5.03 x 3.66 mm. The cutting style is faceted with a radiant cut that balances brilliance and color, and the clarity grade is very slightly included, evaluated at eye level. Color intensity is described as intense, and the polish is excellent. There has been no enhancement to alter color or clarity, preserving the stone in its natural state and confirming its origin in Madagascar. The combination of precise cutting, favorable proportions, and inherent material quality delivers notable light return and a lively play of tone within the bluish green range. For collectors and connoisseurs who prioritize natural provenance and geological authenticity, this sapphire represents a concise example of corundum formed by deep crustal processes, refined by time, and presented with the documentation and standards The Natural Sapphire Company applies to every gemstone.
