1.10 Ct. Grey Star Sapphire from Burma (Myanmar)

One beautiful translucent 1.10 carat oval shape grey star sapphire is presented with precise proportions, weighing 1.10 carats and measuring 5.74 by 5.10 by 3.38 millimeters, exhibiting an oval outline that is well balanced for cabochon presentation. The body color registers as a neutral grey with medium color intensity, producing a soft, cool tone that interacts with light to yield a subdued silvery sheen, translucency is consistent across the profile permitting internal light transmission without significant windowing, clarity characteristics are typical for asteriated sapphires with oriented rutile silk giving the interior a satiny texture rather than discrete inclusions, polish quality is excellent, the surface presents a smooth, reflective finish that minimizes surface diffusion of light and enhances the visibility of the star, enhancement status no enhancement, origin Burma Myanmar, provenance from this region correlates with classical star sapphire material known for fine silk networks and dignified body colors.

The cutting and asterism mechanics of this specimen are the result of deliberate lapidary decisions, the cabochon cut has been executed with a domed crown and a controlled profile height to optimize a six rayed star, the dome curvature is moderate rather than high, this proportion helps maintain a crisp asterism when viewed under a single point light source, the star itself is generated by three intersecting sets of rutile needles oriented at approximately 60 degrees to each other, this three directional alignment produces a six ray star that is well centered and displays clear ray definition, light scattering along the needle orientations creates the classic star banding that crosses the crown, the star is responsive to directional lighting and translates across the dome as the stone or light source is moved, the lapidary focus during preforming and final polishing was to align the needle orientation parallel to the cabochon axis, this ensures that the asterism is symmetric and that the central intersection sits close to the geometrical center of the oval, surface finish was achieved using progressively finer laps and polishing compounds to eliminate micro abrasions, the excellent polish contributes to a tight, bright star and minimizes distracting surface reflections.

From a craftsmanship and connoisseurship perspective this Burmese grey star sapphire is distinguished by its natural, untreated status, the absence of heat or diffusion treatments preserves the original silk structure and body color, this is a key value driver for collectors and for bespoke jewelry designers who prioritize natural provenance, the combination of a 5.74 by 5.10 by 3.38 millimeter footprint with a 1.10 carat weight yields a gem that is versatile for a variety of settings, the moderate thickness and oval format make the stone suitable for bezel settings that protect the girdle and secure the cabochon, alternatively a low profile prong or partial bezel mount can be used where the focus is to present the star face up without excessive metal coverage, when setting orientation must be considered so that the asterism aligns with the intended visual axis of the finished piece, lighting recommendations for optimal display include a single point light source above the gem for sharp star presentation, diffuse overhead lighting will reveal the soft chatoyant background texture, for documentation The Natural Sapphire Company can provide detailed imaging and origin disclosure along with mounting advice tailored to the design, given the excellent polish, natural origin, and well centered six ray star, this specimen appeals to buyers who appreciate technical lapidary quality as well as authentic Burmese provenance, for further technical data, viewing options, or certification inquiries contact The Natural Sapphire Company, our specialists can advise on setting dimensions, protective mounting techniques, and provide high resolution imaging to evaluate star behavior under variable lighting.
