5.89 Ct. Bluish Purple Star Sapphire from Ceylon (Sri Lanka)

This listing describes a natural star sapphire from Ceylon, Sri Lanka, offered by The Natural Sapphire Company. The gem weighs 5.89 carats. The shape is oval, and the cabochon profile measures 12.03 by 8.81 by 5.50 mm. The stone displays a semi translucent body, with a bluish purple overall hue and a medium level of color intensity. The cutting and finishing have been executed to emphasize the asterism, and the polish is graded excellent. No enhancements have been applied to alter the color or clarity of this sapphire, and the material is presented in its natural state as sourced from a Ceylon deposit.

Color and tone are primary determinants of the visual appeal of this sapphire, and this specimen shows a balanced bluish purple that reads differently depending on lighting and background. Under neutral daylight the stone presents a softly saturated purple with a cool blue component that becomes more prominent under stronger, whiter illumination. The medium color intensity allows the central star to remain distinct without the body color becoming opaque, and the semi translucent character supports a pleasing depth to the color rather than a flat appearance. Color zoning is minimal when viewed face up, and the hue and tone are consistent across the gem, which supports predictable performance when set into a piece of jewelry.

The asterism is produced by oriented rutile inclusions, and this sapphire displays a sharp six ray star that centers well on the dome when viewed under a focused light source. The cabochon cutter has preserved an evenly domed profile and symmetrical oval outline, which are important to achieve a clean, well positioned star. The clarity is graded very slightly included when evaluated at eye level, meaning small inclusions are present but do not significantly distract from the star or the overall appearance. These natural inclusions contribute to the asterism and are characteristic of star sapphires. The excellent polish enhances the luster of the dome and helps the star translate crisply from light to dark backgrounds, making the optical phenomenon obvious to the naked eye in appropriate lighting.

For use in jewelry, this 5.89 carat Ceylon star sapphire is suitable for a focal setting such as a solitaire ring, pendant, or a statement pair in custom designs. The oval proportions and moderate depth make the stone versatile for common mounting styles while allowing the star to be aligned along the long axis or the short axis depending on design intent. Because the gem is unenhanced, it will age and respond to cleaning in a predictable way, and standard care for corundum applies, including avoiding harsh ultrasonic cleaning when set in delicate mounting contexts and routine gentle cleaning with warm soapy water and a soft brush.
