0.85 Ct. Bluish Green Sapphire from Madagascar

This sapphire is a transparent 0.85 carat round gem, a weight that places it in a premium category for both everyday wear and refined jewellery designs. Carat weight is the primary indicator of a stone s intrinsic mass, and at 0.85 carats this sapphire balances presence with practicality, offering a perceptible and elegant face up size while maintaining comfortable proportions for rings, pendants, or bespoke settings. The 0.85 carat weight also reflects the level of material conservation and precision cutting required to produce a clean, well proportioned round stone, characteristics that contribute directly to its market value and desirability. For collectors and designers seeking a high quality sapphire that presents like a classic centre stone without the logistical and budgetary considerations of larger carat weights, this gem represents a considered and premium option.

The gem s dimensions are 5.74 x 5.80 x 3.48 mm, measurements that translate to a balanced face up diameter and a pavilion depth that supports effective light return. The round shape with a mixed brilliant cut combines facet arrangements designed to maximize scintillation in the crown, while preserving depth and stability in the pavilion, a combination that contributes to visual depth and lively sparkle. Clarity is noted as very very slightly included when evaluated at eye level, a grade that indicates only minute inclusions that are difficult to detect without magnification, and that do not materially affect transparency or brilliance. An excellent polish further enhances surface brilliance and reduces light diffusion, allowing the stone s internal contributions to be expressed clearly. Together, the precise dimensions, the mixed brilliant cut, the high clarity assessment, and the excellent polish are indicative of deliberate lapidary work and attention to optical performance, qualities consistent with premium natural sapphires.

Color is a defining attribute of this specimen, described as bluish green with medium color intensity. The hue presents a refined blend of blue and green that reads as bluish green under neutral lighting, with medium saturation that affords both depth and versatility. Medium intensity offers a controlled saturation that performs well in various metal settings and under different lighting conditions, maintaining presence without appearing overly dark. Madagascar is recorded as the origin, a source increasingly recognized for producing sapphires with distinctive and attractive color profiles. The stone has been heat treated, a standard and stable enhancement applied to improve color uniformity and clarity, a treatment that is widely accepted within the trade when fully disclosed. The combination of hue, medium intensity, and the confirmed enhancement status yields a predictable and enduring color performance, suitable for pieces intended for regular wear and long term appreciation.
