0.85 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

One transparent 0.85 carat radiant shape yellow sapphire, dimensions 5.93 by 4.61 by 3.39 mm, faceted with a radiant cut, clarity grade very very slightly included evaluated at eye level, light color intensity, and excellent polish. The stone is unenhanced, originating from Ceylon Sri Lanka, and it has been prepared to precise proportions to maximize symmetry and facet alignment. The radiant cut combines trimmed corners with a mixed facet arrangement to balance surface brilliance and internal light return, while the high polish preserves crisp facet junctions and a clean table window. The transparency and the very very slightly included clarity grade mean that light traverses the crystal with minimal obstruction, producing consistent internal reflection and a clear, warm yellow appearance that reads as light and refined rather than deeply saturated.

In comparative terms, this Ceylon yellow sapphire presents reflective qualities characteristic of corundum, with refractive properties that favor strong surface luster and focused brilliance, while exhibiting less fire than high dispersion gems. Corundum typically has a refractive index around 1.76 to 1.78 and a dispersion near 0.018, which yields bright, sharp reflections and good contrast in well cut stones. Compared with diamond, which has a much higher refractive index and dispersion, this sapphire will show less spectral fire but greater color stability and a more restrained, elegant scintillation. Compared with high dispersion alternatives such as zircon, the sapphire offers superior durability and better retention of polish in everyday wear. Relative to common yellow gemstones such as citrine and topaz, this sapphire displays stronger brilliance and a higher index of refraction, resulting in a livelier play of light and a clearer visual presence. Yellow sapphires also tend to show minimal pleochroism compared with certain blue sapphires, so the reflective behavior is relatively even across viewing angles. For settings that emphasize light return, the radiant cut and the stone s excellent clarity produce efficient light reflection and steady sparkle, making this Ceylon unenhanced yellow sapphire from The Natural Sapphire Company a technically refined choice for jewelry that requires both durability and consistent optical performance.
