3.62 Ct. Bluish Green Sapphire from Madagascar

From the soft, shifting soils of Madagascar to the precision workbench of our master cutters, the journey of this sapphire reads like a short epic. Unearthed by artisanal miners who have worked those deposits for generations, this transparent bluish green sapphire began life as a rough crystal shaped slowly by geological time. At The Natural Sapphire Company we traced and selected this piece for its rare combination of clarity and vivid color intensity. We weighed it at 3.62 carats, and it measures approximately 8.25 by 8.14 by 5.72 millimeters, cut in an elegant asscher octagon form. The stone is heat treated, a common and stable enhancement used to bring out the pure richness of the hue, and it received an excellent polish that allows light to move freely across its planes. Evaluated at eye level, its clarity is very very slightly included, which means that to the naked eye the gem presents an alluring transparency and a clean visual field, while still retaining the natural fingerprint that connects it to its origin.

The asscher cut gives this sapphire a distinct personality when it comes to reflection and light play. Unlike a brilliant cut that scatters light into a lively flash of scintillation, or a cushion cut that blends brilliance with softer fire, the asscher style uses concentric step facets to create a hall of mirrors effect. Each plane folds light inward and then returns it in broad flashes of color, so instead of a thousand tiny sparkles you see deep, geometric reflections and an almost architectural luminosity. In this bluish green sapphire those reflections reveal shifting notes of teal and deep ocean blue as the gem turns, and the vivid color intensity amplifies the sense of depth. Compared to other sapphires from Sri Lanka or Madagascar that are cut as rounds or cushions, this asscher presents a calmer, more meditative brilliance, favoring depth and color saturation over aggressive sparkle. When compared to gemstones in the broader category of corundum, such as spinel which often offers bright, bracing brilliance, this sapphire leans toward a refined, internal glow that rewards a slow and appreciative look.

Practically speaking, the way this sapphire reflects light influences how it should be set and worn. In a solitaire ring the asscher facets will catch light from above in broad, dramatic planes, making it ideal for open prong or low bezel settings that allow the geometry to be admired from multiple angles. For a three stone or halo design the stone offers a strong central presence, its step facets providing a steady backdrop against which smaller brilliant side stones can dance. At 3.62 carats the gem reads as significant on the finger while its proportions remain comfortable, the 8.25 by 8.14 by 5.72 millimeter dimensions giving it a generous tabletop and enough pavilion depth to create layered reflections. Compared to other sapphires with more visible inclusions, the very very slightly included clarity of this piece ensures that light is not unduly scattered, preserving both color and brilliance. The heat treatment is stable and customary, intensifying the bluish green hue without compromising the stone s structural integrity, so its reflective quality remains robust and enduring.

This sapphire carries the story of Madagascar in every facet, from the mineral rich earth that shaped it to the expert hands that honed its angles. There is cultural resonance in wearing a gem from an island known for producing a diverse palette of sapphires, and this stone s vivid bluish green evokes oceanic and verdant imagery at once. At The Natural Sapphire Company we take care to document provenance and to present each stone with its full history, and we are happy to guide you in choosing a setting that complements the asscher cut s reflective character. For care, simple soapy water and a soft brush will keep the facets bright, and routine inspections of the setting will protect its clean, architectural lines. If you seek a gemstone that favors contemplative depth, structural elegance, and a tale of origin that invites connection, this 3.62 carat asscher octagon sapphire is a rare and resonant choice.
