1.55 Ct. Bluish Green Sapphire from Madagascar

This 1.55 carat round bluish green sapphire presents as a transparent, lively gemstone, with exact dimensions of 6.85 by 6.79 by 4.76 mm, originating from Madagascar, and with no enhancement. The gem exhibits intense color intensity, a well balanced hue that reads distinctly bluish green rather than leaning too far to pure blue or green, and a saturation that gives the stone depth without appearing overly dark. At typical viewing distances the color remains rich and continuous across the table and crown, with subtle internal color variation that creates depth and complexity rather than obvious zoning. The combination of transparent clarity and intense color produces a strong visual presence, making this sapphire immediately attractive to collectors and connoisseurs who seek natural, untreated material with a pronounced, consistent tone.

The cutting style is a mixed brilliant cut, a deliberate fusion of classical brilliant crown geometry with a modified pavilion architecture that optimizes both scintillation and color return. The crown facets are arranged to maximize break up of light into small flashes of brilliance, while the pavilion has been faceted to encourage controlled light return and to deepen perceived color, a technique especially effective for saturated sapphires. Proportions yield a depth close to 69.8 percent when calculated from the average diameter and pavilion depth, a proportion chosen to favor color saturation and face up size in the round shape. Facet junctions are sharp, symmetry is consistent from facet to facet, and the excellent polish on all facet planes ensures minimal light leakage and strong contrast between bright flashes and darker windows. The result is a balance of lively scintillation and stable color presence, qualities that allow the stone to act as a centerpiece rather than as a supporting accent.

Clarity is graded as very very slightly included when evaluated at eye level, a designation that indicates minimal visible inclusions under normal viewing conditions and eye clean appearance in most mounting orientations. These small inclusions do not interfere with the gemological integrity or durability of the stone, and they provide natural fingerprinting that reassures the gem is unheated and untreated. The excellent polish and precise faceting further mitigate any minor internal features by directing light in ways that conceal rather than emphasize them. As a natural Madagascan sapphire, this gem represents a combination of desirable origin, uncompromised treatment status, and meticulous lapidary work. The Natural Sapphire Company presents this piece as a versatile center stone, ideal for a refined solitaire mounting that showcases the round mixed brilliant face up brilliance, or for a halo or three stone design where its intense bluish green can be contrasted with diamonds or lighter sapphires to amplify its presence. For collectors and discerning buyers who value detailed craftsmanship, natural provenance, and exceptional cut performance, this sapphire stands as a technically refined and visually compelling choice, and our specialists at The Natural Sapphire Company are available to advise on the optimal setting and appraisal considerations.
