1.08 Ct. Green Sapphire from Australia

This marquise shaped green sapphire weighs 1.08 carats, and measures 10.24 x 5.07 x 3.36 mm, providing a well balanced and elegant elongated silhouette. The stone is transparent, with an intense color intensity and a clarity grade described as very slightly included when evaluated at eye level, indicating that inclusions are minimal and do not interfere with the gem s overall appearance. The mixed brilliant cut combines a faceted crown and pavilion geometry designed to maximize light return and scintillation across the marquise outline, and the finish is described as excellent polish, producing crisp facet junctions and clean reflective surfaces. The sapphire has been heat treated, a standard and stable enhancement applied to improve color and clarity, and the origin is Australia, a source known for producing green and parti colored sapphires with stable natural color profiles. The Natural Sapphire Company provides full disclosure of these characteristics as part of the gem s identification and provenance information.

The mixed brilliant faceting in this marquise emphasizes central light return while maintaining lively edge scintillation, the crown facets capture incident light and redirect it through the pavilion for a balanced brightness and contrast pattern. The elongated marquise shape increases apparent size relative to weight, and the 1.08 carat weight combined with the given dimensions yields comfortable proportions for both solitaire and halo treatments. The very slightly included clarity grade means inclusions are small and localized, they are not apparent without magnification when the stone is set and viewed at normal distances, and they do not significantly affect durability. Excellent polish enhances optical performance, ensuring that each facet acts as an efficient mirror to light, which contributes to the gem s brilliance and to sharp scintillation when the piece is moved. The heat treatment applied to this sapphire is stable under normal wear conditions, and it has been used to enhance the stone s natural color and overall uniformity.

Under natural daylight this green sapphire presents its truest and most balanced appearance, daylight s broad spectrum tends to reveal the gem s intense green saturation with cool undertones where present, direct sunlight amplifies brilliance and can produce vivid flashes as crown facets interact with the sun s rays, and in shaded daylight the stone reveals deeper forest green tones with strong depth. Under warm incandescent or halogen light the green may take on warmer olive and golden green nuances, with increased internal glow and a softer, richer appearance as the warm spectrum emphasizes yellow green components. Modern cool white LED lighting and some fluorescent sources can make the stone appear slightly cooler in tone, enhancing bluish green components if present, and these light sources often increase the contrast between flashes and areas of saturated color. In candlelight and other low intensity warm environments the marquise will adopt a more subdued presence, showing deeper saturation and gentle internal flashes rather than sharp scintillation, and the faceting will reveal subtle variations in green as the stone is rotated. The gem may exhibit slight pleochroism, presenting different green tones when viewed from different angles, and this characteristic adds visual complexity and interest across different lighting conditions.

For practical use this marquise green sapphire is suitable for ring centers, pendants, and bespoke designs where the elongated shape can be used to visually lengthen a finger or to create a distinctive focal point. The dimensions and mixed brilliant cut make it adaptable to a variety of settings, however, the pointed ends of a marquise benefit from protective prong work or bezel design to reduce the risk of impact. The very slightly included clarity and the heat treatment do not compromise the gem s stability, and routine care with warm soapy water and a soft brush is effective for cleaning, avoiding harsh chemicals and extreme thermal shock. The Natural Sapphire Company provides documentation of the gem s properties and treatment history to support informed decisions regarding mounting and care.
