0.97 Ct. Blue Star Sapphire from Ceylon (Sri Lanka)

This translucent 0.97 carat oval blue star sapphire measures 6.17 x 4.35 x 3.33 mm, and is expertly shaped as a cabochon to maximize asterism and light performance. The substantial dome height yields a dome height ratio of approximately 0.54 relative to the length, a proportion that concentrates light reflection toward the crown surface and sharpens the six ray star caused by oriented rutile needle inclusions. With a clarity grade of very slightly included evaluated at eye level, the internal features contribute to the classic star effect without compromising translucency, and the vivid color intensity provides saturated blue throughout the body. The excellent polish produces a clean, glossy finish that enhances the star contrast when viewed under a single direct light source. This stone is from Ceylon Sri Lanka, and carries no enhancement, a factor that ensures natural color stability and predictable long term behavior in jewelry. For mounting, the cabochon form benefits from a low profile bezel or secure three or four prong tray that protects the dome while permitting frontal light interaction, and a well centered table orientation will maintain star symmetry in daily wear.

Color interaction with skin tones is critical when translating the gem to finished jewelry, and the vivid Ceylon blue of this star sapphire responds differently to metal choice and skin undertone, information that The Natural Sapphire Company provides to help clients make precise design decisions. On fair skin with cool undertones, settings in platinum or white gold preserve the pure blue hue and accentuate the stone clarity and star contrast, producing a crisp modern look. On fair skin with warm undertones, a thin yellow gold bezel warms the surrounding field, resulting in a slightly richer presentation that complements warm complexion tones without obscuring the star. On medium and olive skin tones, the sapphire reads as intense and saturated, and either white metals for contrast or yellow gold for harmony are suitable depending on whether one seeks visual pop or integrated warmth. On deeper skin tones the vivid blue achieves maximum impact and legibility, and the addition of a subtle diamond halo or a polished bezel can increase perceived brightness while protecting the cabochon surface. Because the gem is unenhanced and finely polished, its color remains the defining design variable, and educators and designers at The Natural Sapphire Company can advise on metal, setting depth, and bezel thickness to optimize star visibility and overall color harmony.
