0.55 Ct. Bluish Green Sapphire from Madagascar

This oval shape bluish green sapphire weighs 0.55 carat, and measures 6.40 by 3.83 by 2.69 millimeters, and it is presented by The Natural Sapphire Company. The proportions of this gem translate to an approximate depth of 52.6 percent relative to the average diameter, a proportion that supports balanced light return while maintaining a slim, elegant profile for bezel or claw settings. The cutting style is a mixed brilliant cut, a deliberate combination of brilliant and step facet schemes that allows the pavilion and crown to be optimized for both scintillation and a steady flash of color. The medium color intensity of this sapphire sits in a sweet spot where saturation is sufficient to convey an unmistakable bluish green presence, while still offering versatility for daytime and evening wear. The stone is transparent, and the excellent polish on each facet plane ensures crisp facet junctions and uninterrupted light passage.

From a lapidary perspective, the mixed brilliant faceting on this oval has been executed to enhance both brilliance and color distribution, with carefully calibrated crown angles and pavilion facets designed to manage light leakage. The crown facilitates dispersion and scintillation through a pattern of triangular and kite facets, while the pavilion employs a modified arrangement that returns a lively balance of pinpoint flashes and broader luminous areas. The oval outline and the facet geometry together accentuate the sapphires pleochroic nature, producing subtle shifts between bluish and greenish directions as the stone is rotated. This dynamic color response is characteristic of corundum from Madagascar, where variable trace element chemistry yields attractive bluish green tones. The medium intensity grading communicates that the gem presents saturated hue without appearing overly dark, and the evenness of the tone across the table and crown provides visual stability in most lighting conditions.

Clarity is graded as slightly included when evaluated at eye level, and this grade is consistent with natural sapphires that have not been filled or otherwise aggressively modified. The minor inclusions are internal and do not compromise the structural integrity of the gem, and they are complementary to the stones identity as a natural, heat treated sapphire. Heat treatment has been applied, a well established and stable enhancement process that improves color uniformity and reduces the visibility of certain mineral inclusions, while retaining the gemological characteristics that allow origin determination to Madagascar. Under magnification the inclusions can serve as internal fingerprints of natural formation, and for many collectors and connoisseurs they contribute to the authenticity and narrative of the piece. The excellent polish reported is a direct result of meticulous finishing, producing high gloss facet surfaces that maximize brilliance and minimize surface graining, and the facet symmetry and pavilion alignment indicate skilled craftsmanship in the cutting and finishing stages.

Beyond the immediate visual qualities, this 0.55 carat oval sapphire is a durable and enduring choice for everyday jewelry, corundum being a nine on the Mohs hardness scale, and able to resist scratches and everyday wear far better than many alternative gemstones. Proper care will ensure that its natural beauty continues to captivate over the years, simple precautions include avoiding prolonged exposure to harsh chemicals, removing the piece during heavy mechanical activity, and following The Natural Sapphire Companys care recommendations regarding professional cleaning and inspection. For settings, the gem responds exceptionally well to both classic solitaire mounts that showcase the oval silhouette, and to more elaborate halo designs that use surrounding diamonds or color contrast metals to intensify perceived size and color. For patrons seeking a personalized piece, The Natural Sapphire Company can advise on optimal metal choice, prong configuration, and the best angles to orient the stone to exploit pleochroism and maximize face up color. This sapphire embodies a combination of precise cutting, considered enhancement, and natural origin that will continue to draw attention and appreciation for generations.
