1.34 Ct. Pinkish Purple Star Sapphire from Ceylon (Sri Lanka)

This star sapphire presents as a translucent, pinkish purple, oval cabochon weighing 1.34 carat, with precise dimensions of 5.41 x 4.85 x 4.71 mm. The cutter has executed a classic cabochon profile, preserving a high, well centered dome that is essential to strong asterism, and the proportions reflect deliberate material economy to keep the star sharp while maximizing yield from the rough. The cabochon cutting style used here concentrates the parallel orientation of fine rutile needles along the sapphire crystal c axis, producing a six ray star that becomes most distinct under a single overhead point light. The modest table diameter relative to dome height enhances the concentration of reflected light into the star, so the asterism reads crisply even at this compact size. For gemologists and experienced jewelers alike, the measurements indicate a stone that is easy to seat into standard oval settings while still presenting a pronounced, three dimensional star when viewed face up.

Optical and clarity characteristics are equally well considered in this example. The clarity grade is very slightly included at the eye level, and those inclusions are predominantly fine, oriented silk that contributes to the star effect rather than detracting from appearance. Translucency allows the internal light scattering needed for asterism without the muddiness that heavy inclusions can cause. Color is described as medium intensity pinkish purple, a tonal range that balances saturation with transparency so that the star is visible against a soft pastel field rather than being lost in excessive depth. The polish is excellent, reflecting meticulous final lapping and polishing, which is particularly important for asterial stones because surface finish directly affects the sharpness and symmetry of the star. There has been no enhancement to this gem, it is natural and untreated, and it originates from Ceylon, Sri Lanka, a classic source known for producing sapphires with delicate pastel tones and fine silk responsible for pleasing asterism.

From a custom jewelry perspective this star sapphire is especially well suited to a variety of design solutions because of its size, shape, and optical behavior. The oval outline at 5.41 x 4.85 mm reads as an elegant center for delicate rings, fine pendants, and bespoke earring compositions, and the relatively tall dome of 4.71 mm provides a strong face up presence that will command attention despite its modest millimeter footprint. For settings, consider a bezel when protection and a clean silhouette are priorities, because the cabochon profile seats securely and a bezel will guard the dome during everyday wear. Alternatively, an open back or a darkened closed back can be used to enhance contrast and amplify the perceived color and star intensity, while prong settings that cradle the girdle are suitable when maximizing visible surface area is desired. Metal choice will influence perceived color, rose gold and yellow gold will warm the pinkish purple tones and accentuate the gem’s feminine character, while white gold or platinum will emphasize the star and produce a cooler, more contemporary aesthetic. For placement of the star, the cutter has centered the asterism on the dome, which simplifies orientation during setting and ensures the star is aligned perpendicular to the finger or pendant face for optimal viewing. Practical considerations include the stone’s durability as corundum, which rates nine on the Mohs scale, making it appropriate for everyday jewelry, while care recommendations include avoiding severe thermal shock and aggressive mechanical cleaning when needle inclusions are present, and preferring warm soapy water and a soft brush for routine maintenance. The Natural Sapphire Company can advise on setting orientation, metal pairing, and mounting techniques tailored to this cabochon so that the final piece preserves and enhances both the aesthetic and the optical performance of this natural Ceylon star sapphire.
