1.12 Ct. Bluish Green Sapphire from Ceylon (Sri Lanka)

This stone is a transparent 1.12 carat emerald cut bluish green sapphire, with precise dimensions of 6.24 millimeters by 5.05 millimeters by 3.65 millimeters, and an overall depth that works out to approximately 64.7 percent of the mean table diameter. The cutting style is a classical emerald cut with stepped crown and pavilion facets, resulting in broad, linear facet planes that emphasize color and clarity rather than scintillation. Clarity is graded as very slightly included when evaluated at eye level, so inclusions are minimal and do not interrupt the planar reflections created by the step facets. Color intensity is described as intense, with a balanced bluish green tonality characteristic of fine Ceylon origin material. The polish is excellent, with crisp facet junctions and a smooth table surface that allow the stone to display its internal color evenly across the table and along the facets. The sapphire has been heat treated, a stable and permanent enhancement commonly applied to Ceylon sapphires to improve color saturation and remove silk like inclusions, and this treatment is consistent with the provenance and cutting tradition associated with The Natural Sapphire Company.

From a faceting and optical perspective, the emerald cut in this sapphire has been executed to maximize face up color while retaining controlled light return through the step style. The crown height appears slightly shallow in order to keep the table large enough to present the intense bluish green in a single plane, while the pavilion depth and step sequence maintain contrast between dark and light planes that is desirable in an emerald cut. This geometry produces a sophisticated windowing characteristic where table reflections show the saturated hue and the stepped pavilion facets create ribbon like bands of color when viewed through the table. Pleochroism is observable in many sapphires from Sri Lanka, and this specimen demonstrates dichroic tendencies, presenting a greener hue when viewed along one axis and a bluer hue along the perpendicular axis, a behavior that complements the stepped facet design and enhances color dynamics as the stone is rotated. The very slightly included clarity grade means that inclusions are not prominent at normal viewing distances and do not compromise the stone structurally, while the excellent polish minimizes light leakage and preserves the crisp contrast typical of a well executed emerald cut.

Durability characteristics make this sapphire highly suitable for daily wear in a wide variety of jewelry types. As a corundum species, sapphire rates nine on the Mohs hardness scale, second only to diamond, which confers excellent resistance to scratching from everyday materials and ensures that facet edges and polish will remain intact under normal wear conditions. Corundum also benefits from good toughness and the absence of true cleavage planes, so it resists chipping and splitting better than many other gem materials when properly set. The specific gravity is typical for sapphire, approximately 3.95 to 4.03, giving the stone a solid weight and feel that is proportionate to its compact dimensions. Optical properties of natural sapphire include a refractive index in the range of 1.762 to 1.770 and a modest birefringence of about 0.008 to 0.010, and these values contribute to the controlled brilliance and sharp facet separation seen in this emerald cut. Heat treatment in this stone is a permanent enhancement and does not adversely affect hardness or stability under normal wear and cleaning. For secure daily wear, I recommend protective settings that defend the stone at its corners such as a bezel or well placed corner prongs, especially for ring applications that experience the most impact, while earrings and pendants can take advantage of the cut to show color without exposing edges. Routine care using warm soapy water and a soft brush is safe, and ultrasonic cleaning is generally acceptable for clean, heat treated sapphires, although professional inspection is advised if the piece has been mounted with delicate metalwork or contains inlaid components.

At The Natural Sapphire Company we select and finish sapphires with attention to these technical parameters so that the wearer gets both beauty and longevity. This 1.12 carat Ceylon emerald cut sapphires combination of intense bluish green color, very slightly included clarity at eye level, excellent polish, and permanent heat treatment makes it an ideal candidate for an everyday engagement ring, a refined bezel set pendant, or sophisticated stud earrings where a step cut will read as elegant and restrained. The cut proportions, durable corundum composition, and thoughtful recommendations for protective mounting together deliver a sapphire that performs well under daily conditions while preserving the optical characteristics that discerning buyers appreciate.
