2.17 Ct. Yellow Rough Sapphire Crystal from Ceylon (Sri Lanka)

This translucent 2.17 carat yellow sapphire presents a naturally organic various shape, with precise dimensions of 9.50 x 5.20 x 4.00 mm, a rough crystal cut, and an excellent polish. The stone displays light color intensity and a clarity grading of slightly included when evaluated at eye level, attributes that communicate a natural origin and character rather than artificial modification. There has been no enhancement to the material, and its provenance is Ceylon, Sri Lanka, as documented by The Natural Sapphire Company. The combination of a gentle yellow tone and a polished but rough crystal form produces a subtle, soft presence that reads as both understated and distinct in hand or mounted in jewelry.

Under direct daylight the sapphire exhibits a soft, luminous wash, with diffuse transmissions of light that emphasize its translucent body color rather than sharp internal reflections. In strong midday sun the stone takes on a slightly brighter yellow, as light passes through the crystalline structure, producing a warm internal glow. Under cool LED or fluorescent lighting the hue shifts subtly toward a paler lemon, and the stone’s translucency favors a milky shimmer over scintillation. Warm incandescent or candlelight deepens the yellow undertone, enhancing the impression of warmth and producing a gentle, creamy radiance. In focused light from a spotlight or small lamp the excellent polish allows modest surface reflections, while the internal slightly included nature scatters light to create a soft, satiny sheen rather than a highly faceted sparkle. These optical behaviors suit settings that highlight the stone’s serene glow and natural character, such as bezel or low profile mounts, which emphasize translucency and protect the softer edges of the rough crystal cut. Maintenance is straightforward, as the absence of treatments means the stone’s appearance will remain true over time when cleaned with mild soap and warm water. For collectors and designers seeking a naturally sourced, characterful yellow sapphire, this Ceylon gem from The Natural Sapphire Company offers measured beauty, clear specifications, and predictable, elegant performance across lighting conditions.
