1.48 Ct. Grey Star Sapphire from Ceylon (Sri Lanka)

This listing presents one beautiful translucent 1.48 carat oval grey star sapphire, with dimensions of 5.30 by 7.29 by 3.96 millimeters, cut in a traditional cabochon style, clarity graded as very very slightly included at eye level, medium color intensity, and an excellent polish, originating from Ceylon Sri Lanka, with no enhancement. The Natural Sapphire Company is pleased to offer this specimen to collectors and connoisseurs who value natural asterism and provenance. The oval outline is thoughtfully retained during cutting to maximize the surface area of the dome while preserving weight and maximizing the visual impact of the star. At 1.48 carats this sapphire carries a presence that is substantial for a classic cabochon, and the translucent body allows the characteristic six ray star to manifest distinctly under directed light. The absence of any heat treatment or diffusion preserves the natural formation of silk inclusions and color distribution, a feature that many educated buyers prioritize when assessing long term value, durability, and rarity.

The cabochon cut is central to the optical performance of a star sapphire, because the domed surface acts as a lens that concentrates and aligns light with the internal structure of the stone. Asterism in sapphires is produced by aligned needle like inclusions, most commonly rutile, which scatter light in narrow bands, and a well executed cabochon will orient those bands so that they intersect as a sharp, centered star. The oval cabochon profile of this piece was shaped with careful attention to symmetry, height of dome, and the orientation of crystal axes, so that the star appears proportionally centered and responsive to movement. The dome height of 3.96 millimeters is sufficient to create a strong reflective surface without overflattening the stone, which can reduce the intensity of the star, or overdoming, which can cause the star to blur. The cutter left enough material to preserve the star under everyday wear, but removed excess rough to enhance luster and eliminate surface irregularities that would otherwise disrupt light flow.

Clarity and color are complementary factors that determine how effectively light interacts with the sapphire, and this stone’s very very slightly included clarity grade at eye level signals that the inclusions are minimal to an experienced observer, yet sufficiently present to create a crisp asterism. The translucent body with medium color intensity balances light transmission with the scattering effect of the silk, producing a star that contrasts pleasingly against the grey background. In practical terms the polish is excellent, meaning the surface lacks transport or polishing pits that could diffuse light and weaken the star’s definition, and the smooth finish contributes to an attractive surface reflection when viewed in ambient lighting. For buyers who understand gem optics, this combination of translucency, medium tone, and restrained inclusion represents an ideal compromise between brilliance, star sharpness, and natural character, and it also supports secure calibration when setting the gem into a ring or pendant.

Ceylon sapphires have a long established reputation for producing stars with sharp asterism and attractive body colors, and provenance from Sri Lanka adds a recognized pedigree that matters to the educated purchaser. Stones from Ceylon can display a fine network of rutile needles that align in three directions, which is the structural basis for the six ray star, and collectors often assign a premium to untampered, naturally asteriated sapphires from this region. The fact that this gemstone is unenhanced enhances both its market desirability and its suitability for collectors who prefer natural, stable gems. At 1.48 carats this oval cabochon is versatile for bespoke jewelry design, and the measured dimensions make it straightforward to set into classic single stone rings, protective bezel mountings, or elegant pendants that allow the star to be viewed and enjoyed. For a discerning buyer, the combination of natural Ceylon origin, cabochon cutting excellence, and an honest clarity grade indicates a lasting, authentic investment.

When considering purchase, buyers will appreciate that the stone displays a reliable and repeatable star under a single light source, which is a key practical test for asterism, and that the overall condition supports regular wear with standard care for a sapphire. Recommended care includes avoiding prolonged exposure to extreme heat and strong chemicals, and routine inspection of any setting to ensure the cabochon is secure. We at The Natural Sapphire Company encourage prospective owners to request additional photographic angles and controlled lighting images if desired, and we can advise on custom settings that preserve the star and protect the stone. For an educated buyer seeking a natural, Ceylon origin star sapphire with authentic asterism, fine polish, and a balanced, translucent grey body, this 1.48 carat oval cabochon represents a compelling choice that combines aesthetic charm with sound gemological attributes.
