1.47 Ct. Bluish Green Sapphire from Madagascar

This transparent bluish green sapphire presents as a precisely cut Asscher octagon, weighing 1.47 carats and measuring 6.12 by 5.80 by 4.28 millimeters. The cutting style is faceted, executed in a classical Asscher arrangement that emphasizes step facets and balanced symmetry. The stone displays intense color, with a bluish green hue that reads consistently across the table in standard lighting. Clarity is graded as very slightly included, assessed at eye level, a grade that indicates only minor internal characteristics which do not detract from the overall visual performance. The girdle and facet junctions show an excellent polish, and the finish quality contributes to clean light return and a crisp facet delineation. Enhancement is limited to standard heat treatment, a stable and widely accepted process used to develop desirable tone and saturation in sapphire, disclosed for full transparency.

The Asscher cut in this specimen is notable for the way it manages light and color. Step faceting produces broad, mirror like planes that create a hall of facets effect within the pavilion, yielding controlled flashes and depth rather than the dispersed scintillation seen in brilliant cuts. For a gem with intense color and very slight inclusions, the Asscher geometry permits the color to be read with clarity, and the flat table preserves the stone character that collectors and experienced setters value. The proportions, as indicated by the dimensions, support a balanced crown to pavilion relationship, and the near square outline with cut corners promotes visual stability on the finger or in a pendant. Faceting precision and polish quality directly influence perceived color and apparent clarity, and this sapphire shows both attributes at a level consistent with fine serviceable stones suitable for high quality custom settings.

Madagascar origin significantly enhances the provenance and appeal of this sapphire. Malagasy sapphires are recognized in the trade for their diverse color range and for deposits that yield material with both distinctive hues and attractive crystal clarity. Geological conditions in Madagascar produce corundum with trace element profiles that can favor green and teal tones, and the bluish green hue exhibited here aligns with that regional signature. Origin adds value in two complementary ways, first by situating the gem within a known and respected geological context that professionals and informed buyers use as a comparative benchmark, second by connecting the stone to sourcing narratives and responsible procurement practices that are increasingly important in the market. Heat treatment is common for Malagasy sapphires and does not negate the value imparted by origin, provided treatment is disclosed, documented, and stable as it is in this instance.

From a practical and valuation perspective this 1.47 carat Asscher octagon sapphire offers a combination of visual presence and gemological soundness. The dimensions make it versatile for ring centres in contemporary and vintage inspired settings, and for small to medium pendants where the step facets will interact attractively with directional light. The very slightly included clarity grade supports confident mounting without extensive masking requirements, and the excellent polish promotes enduring brilliance as the piece is worn. The Natural Sapphire Company stands behind provenance, disclosure, and gemological description, and documentation regarding heat treatment and origin is available to facilitate appraisal and insurance. For buyers seeking a transparent, well finished bluish green sapphire with clear regional identity and precise cutting, this gem presents a technically accomplished and characterful choice.
