0.63 Ct. Black Star Sapphire from Ceylon (Sri Lanka)

One beautiful opaque 0.63 carat round shape black star sapphire, measuring 5.32 x 5.27 x 1.98 mm, presents a classic cabochon form that emphasizes a clear, centered star effect. The stone is graded very very slightly included, evaluated at eye level, and shows a dark color intensity that enhances the visibility of the asterism. The cabochon cut and excellent polish yield a smooth domed surface, allowing light to interact with the needle like inclusions that create the distinctive star. This gem is natural, with no enhancement, and its documented origin is Ceylon, Sri Lanka. The combination of a stable crystal structure and careful cutting produces consistent optical performance, and the compact 0.63 carat weight and near perfect round proportions make it suitable for refined ring or pendant settings.

Over years of wear and careful maintenance the inherent properties of sapphire will preserve the visual integrity and tactile quality of this gem. Sapphire ranks high on the Mohs scale of hardness, providing resilience to everyday wear, and the cabochon polish resists surface abrasion while maintaining the gem clarity and star contrast. The rutile inclusions that form the star are an intrinsic feature of the stone, they do not fade or alter with normal handling, and they continue to produce the shifting, celestial thread like pattern that captivates the eye. For complementary design choices, a White Opal offers a contrasting, luminous field of play of color that can harmonize with the dark, stellar surface of this black star sapphire, giving designers scope for paired or mixed gem compositions. The Natural Sapphire Company stands behind the stated specifications and origin, and recommends routine inspection and gentle cleaning to keep the surface luster high and the asterism distinct, ensuring that this Ceylon star sapphire remains a durable and captivating component of a jewelry collection for many years.
