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

One beautiful translucent 1.77 carat oval purple star sapphire is presented by The Natural Sapphire Company, ready for collectors and designers who appreciate transparent provenance and natural gemology. This gem measures 8.57 x 5.39 x 3.73 mm, which translates to a practical and versatile size for both rings and pendants. The stone has been fashioned as a traditional cabochon cut, allowing the classic asterism of a star sapphire to be displayed with clarity. The color intensity is described as intense, producing a vivid purple hue that remains consistent across the dome of the cabochon. Origin is Ceylon Sri Lanka, a region renowned for producing some of the most desirable sapphires in the market, and importantly this stone has received no enhancement, ensuring buyers are acquiring an untreated natural gem.

The clarity of this star sapphire is graded as very slightly included, evaluated at eye level, which carries meaningful implications for valuation and aesthetics. Very slightly included at eye level means that under normal viewing conditions the stone appears clean to most observers, while minor internal features are present when examined closely. In star sapphires those internal features often include fine rutile needle inclusions that generate the asterism, so a balance between transparency and inclusion is desirable. The cabochon cut is optimal for producing a sharp star, because the orientation of rutile needles relative to the dome determines how distinctly the star will appear under a single overhead light source. This specimen displays a distinct star across the crown when viewed under direct light, benefiting from excellent polish which enhances luster and surface smoothness, improving both light return and the perceived crispness of the star.

From a gemological and collector perspective, provenance and natural state significantly affect desirability. Ceylon Sri Lanka has a long standing reputation for producing sapphires with lively color and good crystal structure, and collectors value provenance because it informs expectations about hue saturation and the character of inclusions. A purple star sapphire is less common than the classic blue variety, making this intense purple example particularly appealing to an educated buyer seeking rarity combined with classical star effect. The absence of heat or other enhancement treatments is a premium attribute, because untreated sapphires carry clear market advantages and appeal to purists who prioritize natural state. At 1.77 carats the weight offers a tangible presence without requiring an oversized setting, and the oval shape with these proportions is ideal for bezel settings and bespoke designs that center the star, while preserving protection and symmetry. The excellent polish and cabochon geometry ensure the star is centered and well proportioned, which are critical factors that experienced buyers and appraisers will note.

Practical considerations for incorporation into jewelry and for long term ownership are straightforward. The gem should be set to emphasize the asterism, using overhead hand or single light sources when evaluating the appearance of the star, and designs that provide a modest dome with protective edges such as a bezel setting will minimize risk of abrasion while presenting the star attractively. Routine care consists of gentle cleaning with warm water proprietary mild soap and a soft brush, avoiding harsh chemical cleaners and ultrasonic baths that can stress settings rather than the corundum itself, although unheated stones are best treated with conservative cleaning practices. For buyers seeking certainty The Natural Sapphire Company can provide documentation of origin and treatment history, and we recommend independent gemological reports for high value purchases to support insurance and resale. This purple star sapphire, with its measured dimensions 8.57 x 5.39 x 3.73 mm, cabochon cut, very slightly included clarity at eye level, intense color, excellent polish, lack of enhancement, and Ceylon origin, represents a compelling combination of rarity and classical gem attributes that will satisfy collectors and designers who demand natural integrity and aesthetic performance.
