1.05 Ct. Purple Star Sapphire from Ceylon (Sri Lanka)

This listing presents a single natural purple star sapphire, weighing 1.05 carats, originating from Ceylon Sri Lanka, offered by The Natural Sapphire Company. The gem is fashioned in an oval shape and measures 5.85 by 5.39 by 3.29 millimeters, a proportion that balances face up presence with wearable depth. The stone is cut as a cabochon, a traditional and preferred style for asteriated sapphires, and it is offered with no enhancement. The clarity has been assessed as very slightly included at eye level, a grade that reflects minor internal features which do not detract from the gem overall. The polish has been evaluated as excellent, contributing to a clean surface and a well defined star under appropriate lighting.

Color and asterism are the defining attributes of this sapphire, and they are displayed with clarity and intensity. The body color is an intense purple, evenly distributed across the table and towards the girdle, with translucency that allows depth without compromising the visibility of the star. The star is sharp and well centered, presenting a six ray pattern that appears most distinctly when the stone is viewed under a single point light source. This phenomenon results from oriented needle like inclusions, commonly called silk, which interact with light to produce the characteristic asterism. The quality of the cabochon cut and the excellent polish both work to enhance the contrast and mobility of the star as the gem is moved, producing a lively optical display.

The cabochon proportions and overall cut quality have been executed to maximize the visual impact of the asterism while maintaining practical dimensions for a variety of jewelry settings. At 5.85 by 5.39 millimeters and a depth of 3.29 millimeters, the gem presents a pleasing face up size for use in rings, pendants, or bespoke pieces where a focused and intense star is desired. The oval outline provides versatility for both modern and traditional settings, while the slightly domed profile supports the projection of the star across the table. Cutters have aligned the core of the cabochon to centralize the star, and the excellent polish ensures that light is not diffused by surface irregularities, preserving the gem photographic properties and the eye visible appeal.

This star sapphire is natural and untreated, with no heat enhancement or diffusion documented, a distinction of relevance to collectors and connoisseurs who prefer stones in their natural state. The origin is Ceylon Sri Lanka, a region with a long established history of producing sapphires known for vibrant color and favorable asterism. The presence of asterism and the very slightly included clarity are consistent with classic Sri Lankan star sapphires, where silk inclusions are often finely oriented. The Natural Sapphire Company provides transparent information about origin and treatment, and the details given here reflect the gem assessment performed at eye level and under standard gemological viewing conditions.

Practical considerations for ownership and setting are straightforward and important for maintaining the gem condition. The cabochon profile benefits from protective settings that shield the dome from direct knocks and abrasion, and settings with a modest bezel or secure prongs are advisable for rings intended for regular wear. Cleaning should be done with mild soap and warm water, applied with a soft brush, and harsh ultrasonic or steam cleaning should be avoided unless recommended by a professional jeweler after an inspection. The stone responds well to light oriented to highlight the star, and its translucency and intense color make it well suited for pieces where the optical display can be appreciated, such as a solitaire pendant or a carefully positioned ring. The Natural Sapphire Company includes detailed information with each gem to support informed selection and to facilitate professional setting and care.
